Thank you for explaining the "why" behind each of these code requirements. Its easier to remember these things when there is a practical reason for their existence in the code.
Got2Learn Good vids. And as you know the code changes every 3 years throughout the country. So inspectors and tradesman are constantly in learning mode to keep up with this 3 year cycle.
My point exactly. Anytime I show a new person something I make it my goal to explain “why” it needs to be done a certain way, and not just “how” it needs to be done. I’ve always found that it gives someone a better understanding of what they are doing, and a stronger appreciation of how critical a failure can be if not done right. ✨✨✨
I just moved into a house and am beginning DIY home repairs. I'm so glad I came across this channel because I have learned so much and just in time so I didn't make too many costly mistakes. Thank you.
As a bathroom remodeling contractor for 40 years I'm aware of all of these. Most (even some journeyman plumbers) are not. My job as a general contractor is to know everyone 's work. Not just carpentry. Good video!
Excellent video. I am a plumbing and gas inspector in Alberta and you're bang on, these are the top 10. A lot of my job is answering questions for people who pull homeowner permits (which I'm happy to do), but this video explains what they need to know so well that I'm going to start sharing your link. Well done.
We have none of this in the UK. No requirement to have pipework inspected. We also don't generally have vent pipes either. Only pipework requirements I'm aware of is that any tank overflow pipes cannot be connected direct to drainage - the overflow has to be visible - so you know it's overflowing - water saving requirement. The other requirement is where there are two sewerage systems - 'foul water' and 'fresh water'. You can't connect toilets to fresh water drains -as that bypasses the sewage treatment works. Many places have just one system and it all goes through sewage treatment works.
@@nuntius1933 The no back flow is a thing here, England and the no over-flows straight into a drain (although that might not be so significant now most of us are on water meters - so we pay for wastage). Other than that, anything goes. There are regs for gas and electricity, but home owners are not bound by those either - they stop non-registered people charging others for work - for gas work at least. My dishwasher drain hose sprang a leak last night - so even quality of water parts used by manufacturers is not that regulated !
Hey Kev, Is there any way we could chat via email, or here?. I'm a new Journeyman, & i'm moving to Alberta in 6 weeks. I want to try & improve my code knowledge, & what better way than to pick the brain of an educated individual in the same field. Hope to hear back, ty
worked for a plumbing shop in 1978.. one of the bins of fittings in the back of the shop where everybody walked was a really full bin of 3/4" galvanized street ells.. an elbow with female threads on one side but male on the other.. i stopped at that bin and screwed 4 street ells together just a few threads.. forcing the last connection to just be touching as i rotated the ells in place.. i hid to the side when the boss walked in.. he came to a skidding stop.. seeing the 4 elbows screwed into each other. he picked the assembly up and examined it closely. smiled and carried it away.. it ended up on his desk as a paperweight.
About the below grade drains, I saw another video about that. They said the same thing about using a 45 street ell in the sanitary tee to improve flow and reduce the chances of clogging. But it also has an added side benefit, in the event that it does plug, the longer sweep makes it much easier to snake out, as snakes do not like sharp turns.
Great info. Problem is that the plumbing inspectors in Atlanta just made up rules to flunk the plumbing on my sister's addition in the 1980's. They disallowed the sanitary-tees in vertical pipes, claiming they had to be combo-tees, as you show for horizontal. They failed a screw-in PVC connection to older cast-iron sewage pipe, saying the PVC pipe had to be leaded into the cast-iron (wouldn't it melt?). They said the hot-water line to the kitchen sink had to be 3/4", even though it necks way down at the facet. The later was in the State code, but a great waste of energy and water waiting for hot water to get to the sink. They wanted the job redone by their "pro" buddies, even though state law allowed doing the plumbing in your own home. Much corruption in building trades.
I’d like to see more videos on code regulations. Especially videos like this “more reasons why you’d fail inspection” I think it’s a fascinating topic, and there’s a lot of things that can go overlooked by a homeowner/DIYer
Code is a very tough topic on the internet. Many cities, counties, provinces and states all have varying codes. Especially handicap accessibility codes and fire protection codes. Different construction methods also change code applications.
Agreed... I watch Plumber Tom a lot... He goes over the IPC, chapter by chapter... You get a lot of why it's done which is why I like his channel too. This is by far the best tips and tricks channel though
I live in an old home built in the early 50's, my washer plumbing is indeed 1.5" pipe. I had issues with it sometimes overflowing too. But since I bought a new "HE" washing machine a few years ago that uses far less water, it's actually been working perfectly fine now. The drain hose on the new washer is only about 7/8" or so, and the 1.5" drain pipe is more than capable of handling the flow from that small discharge hose.
same thing with our shower. The drain is only 1 1/2" and with the old shower head if the drain was a little clogged it would back up but with the low use shower head it doesn't.
All of this is very helpful. But everyone also needs to keep in mind the code varies from one municipality to the next. So check with your local code enforcer if you have any questions.
Yes, there are variations, but the foundation to pretty much all of the is the Uniform Plumbing Code or International Plumbing Code. In my experience much of the variance is in materials, like whether plastic pipe is allowed. I think much of what he mentioned is pretty universal. That said, talk to the local permitting agency for details. Or even call the inspector.
Very well done video. Simple and to the point. Doing a complete tear out of my basement and relocating the bathroom and laundry room. As well as replacing all plumbing. Thanks!
Thanks for putting up this good video with explanations. Those doing their own plumbing should bear in mind that these are "minimum" requirements, and that your local code may require some different or more 'robust' features, .e.g. washing machine drain no less than 1300mm (about 4 ft 6 inch) above floor level _not_ above the point where it ties in to the drain. Likewise, local weather conditions (i.e. winter) may specify where running water, waste lines and vent stacks must go, in order to avoid damage from cold air ingress or being close to a cold outside wall. (These also govern rules for things like sizing of natural gas hot water heater and gas furnace exhaust vents. When roughing in, bear in mind that Code is a _miminum_ standard. In many cases, going one size up, while slightly more expensive in the short term, can prevent future problems that are much more expensive to repair once everything is closed in. As with electrical, it's much better to "do a bit more" at the rough-in stage than try to retrofit later on. If you are hiring sub-trades to do some or all of this work, do not assume they will do it to code, or to the plans, or correctly at all. There are many excellent tradespeople, but every profession has its share of "take the money and run" bums. It's also worth remembering that some "big box" stores sell products - plastic accordion flex pipe sections, for instance - that do not pass code anywhere, usually for very good reasons. Just because they sell it doesn't mean it meets or exceeds local code requirements.
As I am modifying some existing pipes, the previous plumber did a lot of the following examples that would fail inspection 😐. Good to know before I lay the patio. Especially adding a good and convenient clean out access.
FYI. As long as the 90 is a “SWEEP” it can be used. A short sweep is perfectly legal and usually what people get when they say “I need a long sweep”. The fitting that you called a short sweep 90 is actually called a1/4 bend and can only be used for vents or drainage from horizontal to vertical
I was told by an inspector that a medium sweep can be used if you are transitioning from a horizontal run, to a vertical run like a waterfall. I still use a long sweep anyway. Medium sweep NO GOOD for a horizontal turn for waste water.
Reading from the "Cabot" plastic piping handbook, the 3" fitting in question is referred to as a "straight 90 and has a take-up of 1 27/32" used in dry sections of the vent systems only. The 3" DWV fitting known as a 1/4 bend (90) has a radius of three inches and a take-up 3 1/16". Difference in radius and take-up is due to hubs on each end. There is no such DWV fitting as a medium sweep. For DWV piping there is only one radius for each pipe size, unless special order. Standard radiuses are, Short radius= 1 x Dia. of pipe, Long radius= 1 1/2 x dia. of pipe.
@@AyeCarumba221 any SWEEP can be used in verticals to horizontal or horizontal to horizontal applications. BENDS can only be used in drainage from horizontal to vertical or in vents
Great job of describing ways to do, or to not do, something correctly. You've explained well things like,.... your description of why a "Y" is used and not a "T". This puts rationale behind the way drainage gets installed..... so that it will work. Good, valuable information for those who may not be properly trained journeyman plumbers, but want to do things right!
Good ones, but nail plates are not required unless the pipes are 1" 1/2 or less of the edge of the wall. Also You can't catch 2 different fixture from a drain stack unless both trap arms are at the same level using a back to back fitting(double fixture fitting). Regarding to tie-into an existing vent, its something you can do as long as you count all the fixtures units and ensure is capable to vent whatever fixture you will be adding. Clean-outs are required to have when is the end of the line, change of direction exceeding 135°, branches off the main larger than 5' , foot vents and long runs every 100'.
Another reason for using a purpose built device for water hammer is that when that 18" section of pipe fills with water, it sits stagnant. Stagnant water can breed bacteria, like legionnaires disease. Fantastic video!
@ Not be a pacifist, alarmist or to high-jack this comment, but keeping the major concern in sight relieves unnecessary worry: First, the device's primary intent is to address water hammer and water-logging of vertical-pipe shock absorbers, of which a draining of the supply line can usually be done with minimal effort. Secondly, the contraction of the bacteria is generally by inhalation of contaminated water mist. Typical chlorination by the water company is enough to impede the bacteria's proliferation but not sterilize a potable water supply completely; pH, temperature, time and other conditions can affect its efficacy. Also, copper pipes have an ability to suppress growth. Biofilm can also form within the system. I'm not a professional but do have experience and familiarity in the field and of the subject as well as a big concern of the vulnerability. I would be more concerned about hot water storage tank temperature before this (i.e. don't turn the temperature down to save on heating costs), and the conflicting issue becomes the allowable hot-water supply temperature (105F-120F, residential) versus this bacterial suppression (140F @32 mins., disinfection @158F-176F with circulation being beneficial); the answer - a mixing valve (thermostatic is the automatic of that). So at this point we have costs creeping higher and higher where history does not show a problem within this small specific area of focus (shock absorbers - the issue is more complex) although it is technically logical as the OP stated. Still, it is much more about inhalation of contaminated mist.
What's code today, can be a violation tomorrow. It's always changing. Not being to code, doesn't necessarily mean the job is bad, or that it won't work properly for many decades.
Sometimes when someone follows existing codes and then after it is in service the powers that be realize they screwed up . A perfect example is a full size drip leg on a gas pipe and someone decides to add extra appliances with total disregard to the cubic ft demand of the added load
Great illustrations to screen shot for showing customers what's happening in their system behind the walls. Nice job. Thanks for putting this together.
My 1 century old building has many thing not "up to code" because there were not any code for many thing. -No Shock absorber. (I did talk about my mom to not snap close foset because old rusted iron pipe could burst from their thin grinded wall) -Many short 90° turns, also many pipe were done flat 0° so being so old the house ever so slightly sinked in the ground and now some pipe have negative ~-1 to -2° -Many if not most 45° Y-Pipe on pillar sewer pipe are like at 3:13 So a mix of old pipes filled with junk plus that angle make most sink/bath and wat not "gurp"
All great stuff, I'm no longer an inspector, but appreciate this as a refresher for work I do myself :) AT 03:50 you'd hear gurgling as the sink drained, an excellent indicator of a venting/drain problem :) great work, thumbs UP!
At least by IPC code mostly right. Short sweep 90’s are allowed for horizontal to vertical transition and for directly come out of wall to a fixture. Double wye or wye fittings are not permitted to a fixture branch as shown unless it is vented. (Of course if the branch is vented his previous example of an incorrect why in 45 combination would also be permissible) A cross or double tee is permitted but most plumbers who have ran a drain machine will tell you 2 separate tee’s. You absolutely can tie into another vent. His standpipe example is tricky because for washing machines you need to have soapsuds relief (it’s just a special venting style). Total vent size is 1/2 of the drain pipe served with a minimum of 1 1/2 inches so one and a half inches canserve a 3 inch main. Venting on most houses can be combined and come out roof in one single pipe.
I'm currently doing some DIY work on my place. We are about to start plumbing. You mention that vents can usually be connected to exit the house as one pipe. What would be the requirements for that? All my fixtures are within an 15x18 ft area (estimate) but I kept them close to each other to save on plumbing supplies.
trance_dance 30 Does vary in code but most use IPC. So you need a vent pipe to be 1/2 the drain pipe served with a 1-1/2 inch minimum. If the house main drain is 3” then it’s 1-1/2” If it’s a 4” main then it’s 2” vent needed. And when you exit thru the roof in frost areas you need to increase pipe size to 3” vent just before you exit so your vent doesn’t frost over. All of your other individual vents can tie into this main vent. Vents will slope allowing moisture to go down the drain. Also because vents are flowing air, tee fittings will upside down on a vent only line.
Vents are sized not by the drain size although it could be a good rule of thumb but sized by the number of fixture units for the fixtures in the system. For instance a full bathroom is 5 fixture units so an 1 1/2" pipe is adequate but if you tie a kitchen sink to that vent it would add 2 fixture units to that and if there are any horizontal runs above that tie in you would have to increase your pipe size. once you get over 10 fixture units horizontal runs must be increased to 2 1/2" and so forth.
A double sanitary tee makes near impossible to run a snake through it since it goes right through to the other sink and a clean out is not practical since there usually is not enough room. Where I live we use double "Y" or off set the drains. Sanitary Tee's also have a lot of resistance with flow even vertically installed.
I’m an electrician by trade but also a finish carpenter and I can fix anything. I do plumbing too Any crackhead can glue pipe together and “ make it work “ But it’s knowledge spitting, like this guy, that turns us closer to craftsman and professionals. I follow the general rule of only using a hard 90 on vents. It was nice to learn that they can also be used on toilets too. Learning about other trades helps us all out and makes us better craftsman. Thanks for sharing your knowledge! You do great service to others
You’re wonderful!!!! We just finish the plumbing code module and I learned several rules even more than in school!!!! Your channels is way too professional 😂😂😂 way beyond for doitselfers
Man I really admire how informative and quality this video is. I've been studying plumbing codes when I can and was familiar with some of these. I learned some new as well,definitely a video that will save many people's butts . Keep it up man,you and roger wakefield are my favorite youtube channels when it comes to plumbing.
Thank you so much Ethan, I appreciate all of your comments and I am glad you learned something, mission accomplished for me, share if you can, it really helps!!
In my area, the 2" washer standpipe has been required for as long as I remember (early 90s). Also, they don't allow normal pipe to be used as water hammer arresters. They have to be the bladder type. They were required for washing machine and dishwasher lines.
Drill plates are not always required for plumbing or electric; they’re only required when the distance from the face of the stud/joist to the surface of the pipe/wire is too little. A simple sanitary T on the flat won’t work for long, especially with toilets as the flow can hit the T and split leaving solids to build up.
In the area where I live a test stack with 10 ft of water would freeze in the winter Here all the lines a capped and a air gage is used and filled with pressures air and it must hold pressure.
The city of Knoxville TN inspectors have always been tough on handicap dimensions and all the things you mentioned They were also particular about commercial kitchens especially when it comes to proper venting of floor sinks and floor drains
Now, that was informative. If you're doing things yourself, this was mighty helpful and important. ' Nothing could be more frustrating than getting a fail because you didn't use a "long sweep" ell and just because you didn't realize the dif. I thought this was a great video
Honestly, I'm looking toward designing my own homestead in 1-3 years, so coming across this video on my recommended list was awesome! Immediate subscribe! While I'm intending to thoroughly read through the codes and make sure I am up to them in the design phase before even starting buying land and building, it is good to know the reasons why for things that would cause a failed inspection. I did a lot of work helping my godfather (who passed this winter from cancer) with remodeling an apartment building he was a caretaker of when I was younger, and I did plumbing, electrical, and basic carpentry work then, as well as taking an architecture class later. I know what I don't presently know now I can learn, especially with so much information online including the different codes, but it is wonderful to come across videos like that which actually explain the reasoning and show examples. Thank you!
@@Got2Learn thank you. My godfather had fought his cancer into remission three times before it finally took him. He and my father (who is still alive and he and my mother want to join me on the homestead since we're already in an apartment together) both taught me a lot about practical skills, and gave me the room to try things here and there. I was still in junior high when I fixed a toaster they let me take apart and use a voltmeter on, and replace a piece on a PS1 original with a piece from a thrift store cd player. My godparents and parents may at times have irritated me, as all parents occasionally irritate their children, but they were good teachers of useful skills.
@@VitaKet unfortunately, no. The plan was to purchase land and build a small home for my parents, and a separate one for me. However, because they're both disabled and making just high enough to have a spenddown in our state, very few other states are possible for moving to, without them losing medicare. Even moving outside our county would mean a massive jump up in co-pays due to programs here that help... and the price of land is too high within the county for anything that allows residential, let alone the fact that it has stricter building codes limitations than other places we were looking into before, which aren't feasible for them to move to at all. We're even in the cheapest apartment units in town, and yet the price of rent, utilities, food, co-pays, etc, mean that they wouldn't survive without me helping as able. Maybe if I ever make enough to get them set up somewhere that they're on half as much rent to me, or none at all, then I could do whatever separately wherever I wanted... but I'm not about to abandon them when no one else would help.
Good description on the plumbing code. The #6 violation, is still a violation. The double TY fitting must be a double Y fitting, this will prevent the snake from passing from one side to the other, if the drain is plugged down stream of where the 2 lines meet.
Very nice instructional videos. I like watching your videos to help me improve my knowledge and skill level. Very impressed with the smooth and clear speaking of a complex technical dialog. A master is distinguished by making difficult tasks appear easy. Great Job 👍
Other than replacing taps I would never do any plumbing myself but I love learning this so I understand what others have done. I had a new bathroom installed a few years ago with - necessarily - exposed outdoor pipes (I'm in Australia so no issues with freezing). I now know why all the things (e.g. the cleanout) have been installed as I am sure the rules are similar here to in Canada or the US
in my country (easten europe) you do it better by yourself because you don't really have a choice. the reason is that there are no good plumbers and they don't know any of those rules and regulations. the good ones emigrated to western countries and the ones that remained are extremely expensive and not available because they are working for important jobs only (not housing)
Great job and as someone that does their own plumbing in remodeling jobs, I learned the code the hard way, well before youtube was invented and well before AOL...:) But, I only needed once to learn...Thanks so much for putting this up, it's nice to take time out of your life to help others, if everyone did that, the world problems would get sorted out much faster...Namaste!
When I was a residential new construction plumber no inspector was the same. We had to remember what area we were in whether it was a city or county inspector. They were all different. Some things were the same. It resorts back to the code book. It says left to the discretion of the code inspector.
Interesting, in my 30 plus years as a codes consultant for over 150 jurisdictions, I never saw any legally adopted code allow inspector discretion. The codes are written in mandatory language; if an inspector claimed he had discretion he was flying blind.
Regular 90*s can be used on drainage when going from horizontal to vertical, long sweeps on horizontal to horizontal or vertical to horizontal transition
There are a lot of factors here that I just couldn't mention or the video would have been 3 times as long but yeah, there's some places they are allowed and some not, thanks Pat!
I never understood this. Reg 90s on a horizontal position, less bend, but HAVE to use long turn 90s from horizontal to vertical. Can someone please explain this to me?
@@path3848 Negative. Read your national code book. Got my NC P1 master licenses in 2001 and this was a big reason people failed. Not naming fittings properly.
Great video! I have a few questions: 1. If a drain line is going from horizontal to vertical, should a short or long sweep 90° elbow be used? 2. Can a sanitary be used on its back for venting? The vent would serve the kitchen sink (with dishwasher and disposal) and the tub/shower. 3. Can a double sanitary tee (2in inlets 3in top and bottom) be used in a scenario where one side is the inlet for the kitchen sink (with dishwasher and disposal) and the tub/shower and the other inlet is the bathroom sink and a washer (pumping action discharge)?
5:08 why could you not connect a new fixture to an existing vent pipe? If the existing vent pipe was sufficient size and distance, it looks like it would have been OK in new construction, why not OK in addition? Thanks Wonderful video. Thumbs up.
@@Got2Learn I had the same question. I'm planning on adding basement fixtures to an existing 2 inch vent currently serving 6 DFU's on the first floor. My plan is to add another 6 DFU's which will be only my ejector pump for a total of 12 DFU's. UPC says a 2 inch vent can serve up to 24 DFU's. I also cannot find in the UPC code book where this is prohibited. Thanks.
Thank you for the awesome videos. I recently had to remove quite a bit of a 3 in waste stack to allow foundation guys to repair a structual wall. The tip about the horizontal sanitary tee saved me from a mistake since that is how they originally did it on my 3 in waste line where it merges with the 4 inch soil pipe. And yes I used to have to clear that blockage about once a year. Fortunately there was one clean out.
Dude, this video was awesome and so informative. I just started plumbing this week and I felt so lost and this is the first video that gave me an understanding of how certain things work. Instant like and subscribe. Please continue to put out more vids
Some of this is brilliant but others are unheard of in the UK. Like drill plates, over here it is the dry liners fault if they put a screw though a pipe. Also 2 inch trap and upstand for a washing machine is so over kill especially as it most always T's into a 2 inch float straight away.
I moved from the USA to Norway, where they also do not use protective nail plates. When my house was being built, I made and installed my own and the plumbers and inspector all commented on what a great idea that is. It also has saved me a couple of times both when I installed the sheetrock and afterwards when hanging shelves. I much prefer preventing an accident over someone being liable for one.
Mr Sam Drywallers here are idiots 😂 Just kidding. Really though, they’re often in such a hurry in new builds that I could totally see someone not marking the sheet for the locations of piping, or not marking it properly, then screwing through a line 😬 As for the 2” standpipe for laundry, I wonder if it’s an appliance thing. Maybe the washers here put out more volume when draining? 🤷🏼♂️
Just imagine if the dry wallers drill a screw into a main copper supply and the screw only lets only a bit of leakage out , you won’t know till you see your drywall getting moldy, the nail plates are just an extra precaution.
@@orboflightning Just looking at how you boys do it over the pond, seems like you run a lot of pipes through timber! Must be loads of holes to cut! Can see how those drill plates come in handy. We almost always have a void to run pipes, then the dry liners put up sheet steel stud work and then plaster board/ dry wall on top of that. Much less likely to put a screw through a pipe like that.
@@armandopena7921 true. But that's not a precaution that should fall on the plumbers. The drywallers should be doing that, if they are too incompetant to be sure of where they are putting their screws.
So well presented and explained. I love your use of diagrams. Also, I learned about that shock absorber thing from your other video :D Thanks for making these excellent videos!
For #6, some codes require a clean out above a double sanitary tee, otherwise when snaking, the snake can jump to the other side of the tee and never be able to go down the stack toward the clog.
As a PM keeping on top of codes regardless of the servicer, ie: plumbing, electrical, framing, roofing…is a constant issue, and daily inspections are a must…best just to have high quality contractors to avoid foolishness that inspectors inevitably will derail a project if it’s unacceptable…
Vents lower than flood rim of fixture:-- Although an odd duck for sure, the configuration for an island vent has a workaround for being an exception. i also love wet vents which usually get a knowing nod of approval from inspectors. I don't know your locale but in Los Angeles I stopped putting T&P on water heaters and instead just put a pressure relief outside by the shut off. No more pans or drain issues with old heaters inside closets. Always passed. Not appreciated enough is the satisfaction of watching a main line stoppage let go, after you've been playing catch and release with a forest of roots, letting it tangle up just to the edge of the cable flipping in the cage, then yanking back, like fighting a marlin; then it goes BOOM like thunder and you may even have to hook the cable up to your truck and pull out a 10 ft tail of magnificent roots. You feel like mounting them as a trophy! Retired plumbing contractor now, but thinking back, I enjoyed being Roto-Rooter man in L.A. Hollywood more. Every job was an emergency; calls in the middle of the night were like sweeping out of your bat cave, and whether you arrived at a swank Beverly Hills restaurant, a mansion on the hill, or some low rent apartment complex, you came in like a cowboy and everyone followed your commands, rich or poor. flooding sinks from floors above, main lines backing up into basements at exclusive country clubs. But all of them open sesame to you, fair haired hero of the moment!
I am a commercial plumbing inspector for the City of Los Angeles - I LOVE watching your videos. I see these violations ALL the time even though I only inspect commercial which here, also includes new apartments, condos and townhouses where 3 or more units are attached. We can always tell when we the a contractor who "builds high end homes" tries to do a commercial job. It is correction after correction.... We do out best to educate. The "B" does not always mean general!
fascinating. One other point more about the old 18 inch hammer arresters they used to use those dead leg pipes, they end up filling up as the water absorbs the air and fills the pipe with stagnant water that can actually breed bacteria and begin to contaminate your tap water, Also why in any old house I have lived in I never drink strait from the tap, I always only use filters. a 40 year old house, who knows wha'ts in those pipes.
A 40 year old house in the UK is a new build. My home is 120 years old, its not even classed as an old house. I still have lead water pipes, with a bit of copper. Certainly no plastic pipe. My friend lives in a 400 year old house with its own well.
Everything there you explained was correct my hats off to you that being said you could have a video that's 3 hours long explaining a whole lot more thank you for explaining what you did

Awesome, thank you so much!
Got2Learn Good vids. And as you know the code changes every 3 years throughout the country. So inspectors and tradesman are constantly in learning mode to keep up with this 3 year cycle.

As someone that does plumbing i can say it all comes down to the inspector and what you get him for lunch
You buy inspectors lunch? They have about 5 minutes to give me a sticker and get off my job before they end up in a trench somewhere lol
I used to worry about what to get an inspector for lunch.

I am very thankful of your comment Kevin, I really appreciate your kind words :)
We have none of this in the UK. No requirement to have pipework inspected. We also don't generally have vent pipes either. Only pipework requirements I'm aware of is that any tank overflow pipes cannot be connected direct to drainage - the overflow has to be visible - so you know it's overflowing - water saving requirement. The other requirement is where there are two sewerage systems - 'foul water' and 'fresh water'. You can't connect toilets to fresh water drains -as that bypasses the sewage treatment works. Many places have just one system and it all goes through sewage treatment works.
@@nuntius1933 The no back flow is a thing here, England and the no over-flows straight into a drain (although that might not be so significant now most of us are on water meters - so we pay for wastage). Other than that, anything goes. There are regs for gas and electricity, but home owners are not bound by those either - they stop non-registered people charging others for work - for gas work at least.
My dishwasher drain hose sprang a leak last night - so even quality of water parts used by manufacturers is not that regulated !
Hey Kev, Is there any way we could chat via email, or here?. I'm a new Journeyman, & i'm moving to Alberta in 6 weeks. I want to try & improve my code knowledge, & what better way than to pick the brain of an educated individual in the same field. Hope to hear back, ty
I am a plumber and you explained it perfect will share this video with all new employees great stuff. Best plumbing video I have seen on UA-cam 👍
Awesome Alex, thank you so much for sharing!
Where can I find these codes?
Great job! Unlike 100
% of all UA-cam videos, it was short, informative, and to the point!
worked for a plumbing shop in 1978.. one of the bins of fittings in the back of the shop where everybody walked was a really full bin of 3/4" galvanized street ells.. an elbow with female threads on one side but male on the other.. i stopped at that bin and screwed 4 street ells together just a few threads.. forcing the last connection to just be touching as i rotated the ells in place.. i hid to the side when the boss walked in.. he came to a skidding stop.. seeing the 4 elbows screwed into each other. he picked the assembly up and examined it closely. smiled and carried it away.. it ended up on his desk as a paperweight.
About the below grade drains, I saw another video about that. They said the same thing about using a 45 street ell in the sanitary tee to improve flow and reduce the chances of clogging. But it also has an added side benefit, in the event that it does plug, the longer sweep makes it much easier to snake out, as snakes do not like sharp turns.
Great info. Problem is that the plumbing inspectors in Atlanta just made up rules to flunk the plumbing on my sister's addition in the 1980's. They disallowed the sanitary-tees in vertical pipes, claiming they had to be combo-tees, as you show for horizontal. They failed a screw-in PVC connection to older cast-iron sewage pipe, saying the PVC pipe had to be leaded into the cast-iron (wouldn't it melt?). They said the hot-water line to the kitchen sink had to be 3/4", even though it necks way down at the facet. The later was in the State code, but a great waste of energy and water waiting for hot water to get to the sink. They wanted the job redone by their "pro" buddies, even though state law allowed doing the plumbing in your own home. Much corruption in building trades.
I’d like to see more videos on code regulations. Especially videos like this “more reasons why you’d fail inspection” I think it’s a fascinating topic, and there’s a lot of things that can go overlooked by a homeowner/DIYer
Code is a very tough topic on the internet. Many cities, counties, provinces and states all have varying codes. Especially handicap accessibility codes and fire protection codes. Different construction methods also change code applications.
Agreed... I watch Plumber Tom a lot... He goes over the IPC, chapter by chapter... You get a lot of why it's done which is why I like his channel too.
This is by far the best tips and tricks channel though
Thank you thank you! Your videos are just so fantastic, the way they not only say what works and what doesn’t, but you also explain WHY!
I appreciate that you actually explained WHY these are violations.
#10 is fun to deal with on big homes with open floor plans. There is always a second-floor bath over the 1st-floor living room that is 40 x 40.
I really thank you for the clear demonstration as an animation, it really helps rather than just explaining verbally. Well dobe 👍👌🙏
😇😇😇
In Maine, If you put a cleanout on a vertical drain through your slab, you must put an access panel in the wall
I live in an old home built in the early 50's, my washer plumbing is indeed 1.5" pipe. I had issues with it sometimes overflowing too. But since I bought a new "HE" washing machine a few years ago that uses far less water, it's actually been working perfectly fine now. The drain hose on the new washer is only about 7/8" or so, and the 1.5" drain pipe is more than capable of handling the flow from that small discharge hose.
Awesomeeee!
same thing with our shower. The drain is only 1 1/2" and with the old shower head if the drain was a little clogged it would back up but with the low use shower head it doesn't.
All of this is very helpful. But everyone also needs to keep in mind the code varies from one municipality to the next. So check with your local code enforcer if you have any questions.
Yes, there are variations, but the foundation to pretty much all of the is the Uniform Plumbing Code or International Plumbing Code. In my experience much of the variance is in materials, like whether plastic pipe is allowed. I think much of what he mentioned is pretty universal. That said, talk to the local permitting agency for details. Or even call the inspector.
Very well done video. Simple and to the point. Doing a complete tear out of my basement and relocating the bathroom and laundry room. As well as replacing all plumbing. Thanks!
Yeee hawww, thanks buddy!!
Thanks for putting up this good video with explanations. Those doing their own plumbing should bear in mind that these are "minimum" requirements, and that your local code may require some different or more 'robust' features, .e.g. washing machine drain no less than 1300mm (about 4 ft 6 inch) above floor level _not_ above the point where it ties in to the drain. Likewise, local weather conditions (i.e. winter) may specify where running water, waste lines and vent stacks must go, in order to avoid damage from cold air ingress or being close to a cold outside wall. (These also govern rules for things like sizing of natural gas hot water heater and gas furnace exhaust vents.
When roughing in, bear in mind that Code is a _miminum_ standard. In many cases, going one size up, while slightly more expensive in the short term, can prevent future problems that are much more expensive to repair once everything is closed in. As with electrical, it's much better to "do a bit more" at the rough-in stage than try to retrofit later on. If you are hiring sub-trades to do some or all of this work, do not assume they will do it to code, or to the plans, or correctly at all. There are many excellent tradespeople, but every profession has its share of "take the money and run" bums.
It's also worth remembering that some "big box" stores sell products - plastic accordion flex pipe sections, for instance - that do not pass code anywhere, usually for very good reasons. Just because they sell it doesn't mean it meets or exceeds local code requirements.
Well said Flying Beaver!!
I don't know about others but I am keeping this as a reference to be checked any time I do any plumbing . Great video man !
Hehe, that's so cool! Thanks Robert, and share if you can :)))
As I am modifying some existing pipes, the previous plumber did a lot of the following examples that would fail inspection 😐. Good to know before I lay the patio. Especially adding a good and convenient clean out access.
FYI. As long as the 90 is a “SWEEP” it can be used. A short sweep is perfectly legal and usually what people get when they say “I need a long sweep”. The fitting that you called a short sweep 90 is actually called a1/4 bend and can only be used for vents or drainage from horizontal to vertical
I was told by an inspector that a medium sweep can be used if you are transitioning from a horizontal run, to a vertical run like a waterfall. I still use a long sweep anyway. Medium sweep NO GOOD for a horizontal turn for waste water.
U shouldn’t be using a short sweep u should be using a San T with a vent. The name applies to both you can call them bends or refer to them in degrees
Reading from the "Cabot" plastic piping handbook, the 3" fitting in question is referred to as a "straight 90 and has a take-up of 1 27/32" used in dry sections of the vent systems only. The 3" DWV fitting known as a 1/4 bend (90) has a radius of three inches and a take-up 3 1/16". Difference in radius and take-up is due to hubs on each end. There is no such DWV fitting as a medium sweep. For DWV piping there is only one radius for each pipe size, unless special order. Standard radiuses are, Short radius= 1 x Dia. of pipe, Long radius= 1 1/2 x dia. of pipe.
@@AyeCarumba221 any SWEEP can be used in verticals to horizontal or horizontal to horizontal applications. BENDS can only be used in drainage from horizontal to vertical or in vents
Great job of describing ways to do, or to not do, something correctly. You've explained well things like,.... your description of why a "Y" is used and not a "T". This puts rationale behind the way drainage gets installed..... so that it will work. Good, valuable information for those who may not be properly trained journeyman plumbers, but want to do things right!
Thank you very much, have a great day Guy!
I live in a rural area & don't even need to have plumbing inspected, but this is good to know just so you know you did a good job & did it right...
Good ones, but nail plates are not required unless the pipes are 1" 1/2 or less of the edge of the wall. Also You can't catch 2 different fixture from a drain stack unless both trap arms are at the same level using a back to back fitting(double fixture fitting). Regarding to tie-into an existing vent, its something you can do as long as you count all the fixtures units and ensure is capable to vent whatever fixture you will be adding. Clean-outs are required to have when is the end of the line, change of direction exceeding 135°, branches off the main larger than 5' , foot vents and long runs every 100'.
Another reason for using a purpose built device for water hammer is that when that 18" section of pipe fills with water, it sits stagnant. Stagnant water can breed bacteria, like legionnaires disease.
Fantastic video!
Yes, forgot to mention that, thank you very much! Please share if you can :)))
Small comment, if you don't mind, but "harbor" bacteria is more accurate.
How true is that since all my houses and friends houses all have pipes that go past the faucet?
@ Not be a pacifist, alarmist or to high-jack this comment, but keeping the major concern in sight relieves unnecessary worry: First, the device's primary intent is to address water hammer and water-logging of vertical-pipe shock absorbers, of which a draining of the supply line can usually be done with minimal effort. Secondly, the contraction of the bacteria is generally by inhalation of contaminated water mist. Typical chlorination by the water company is enough to impede the bacteria's proliferation but not sterilize a potable water supply completely; pH, temperature, time and other conditions can affect its efficacy. Also, copper pipes have an ability to suppress growth. Biofilm can also form within the system.
I'm not a professional but do have experience and familiarity in the field and of the subject as well as a big concern of the vulnerability. I would be more concerned about hot water storage tank temperature before this (i.e. don't turn the temperature down to save on heating costs), and the conflicting issue becomes the allowable hot-water supply temperature (105F-120F, residential) versus this bacterial suppression (140F @32 mins., disinfection @158F-176F with circulation being beneficial); the answer - a mixing valve (thermostatic is the automatic of that). So at this point we have costs creeping higher and higher where history does not show a problem within this small specific area of focus (shock absorbers - the issue is more complex) although it is technically logical as the OP stated. Still, it is much more about inhalation of contaminated mist.
Im a huilding engineer apprentice, and I always wondered how those water hammer cylinders worked... Thanks!
What's code today, can be a violation tomorrow. It's always changing. Not being to code, doesn't necessarily mean the job is bad, or that it won't work properly for many decades.
Totally agree with you.
Sometimes when someone follows existing codes and then after it is in service the powers that be realize they screwed up . A perfect example is a full size drip leg on a gas pipe and someone decides to add extra appliances with total disregard to the cubic ft demand of the added load
screw code
it always comes down to the inspector's EGO
Lll
Great illustrations to screen shot for showing customers what's happening in their system behind the walls. Nice job. Thanks for putting this together.
Thank you so much Giovanni, I really appreciate your comment, don't forget to share :)
I'm going to school for plumbing. I found this video fascinating. thanks for the content.
Metwood joist reinforcers are really handy when homeowners or builders dont want to build a box and want 3" pipe run through floor joists.
Never even knew these existed, thanks! (link to these: www.metwood.com/joist-reinforcers)
My 1 century old building has many thing not "up to code" because there were not any code for many thing.
-No Shock absorber. (I did talk about my mom to not snap close foset because old rusted iron pipe could burst from their thin grinded wall)
-Many short 90° turns, also many pipe were done flat 0° so being so old the house ever so slightly sinked in the ground and now some pipe have negative ~-1 to -2°
-Many if not most 45° Y-Pipe on pillar sewer pipe are like at 3:13 So a mix of old pipes filled with junk plus that angle make most sink/bath and wat not "gurp"
All great stuff, I'm no longer an inspector, but appreciate this as a refresher for work I do myself :) AT 03:50 you'd hear gurgling as the sink drained, an excellent indicator of a venting/drain problem :) great work, thumbs UP!
You are most welcome, please share if you can, it helps the channel tremendously ✌✌

@@FrederickDunn it's important to me and I always make it priority #1, thanks for noticing Fred!
I’m a plumber in massachusetts and we have to take a refresher class 8hours a year. Fairly new rule.
@@daveatkins3568 sounds like a good idea, it seems to me that the rules keep changing; just hope it's not another money grabber?
Great video. Good job explaining. Though, I'm unclear when adding a new fixture why it is not acceptable to tie into an existing vent???
Thanks, the reason for that is sizing.
At least by IPC code mostly right.
Short sweep 90’s are allowed for horizontal to vertical transition and for directly come out of wall to a fixture.
Double wye or wye fittings are not permitted to a fixture branch as shown unless it is vented. (Of course if the branch is vented his previous example of an incorrect why in 45 combination would also be permissible) A cross or double tee is permitted but most plumbers who have ran a drain machine will tell you 2 separate tee’s.
You absolutely can tie into another vent. His standpipe example is tricky because for washing machines you need to have soapsuds relief (it’s just a special venting style). Total vent size is 1/2 of the drain pipe served with a minimum of 1 1/2 inches so one and a half inches canserve a 3 inch main. Venting on most houses can be combined and come out roof in one single pipe.
I'm currently doing some DIY work on my place. We are about to start plumbing. You mention that vents can usually be connected to exit the house as one pipe. What would be the requirements for that? All my fixtures are within an 15x18 ft area (estimate) but I kept them close to each other to save on plumbing supplies.
trance_dance 30
Does vary in code but most use IPC. So you need a vent pipe to be 1/2 the drain pipe served with a 1-1/2 inch minimum. If the house main drain is 3” then it’s 1-1/2” If it’s a 4” main then it’s 2” vent needed. And when you exit thru the roof in frost areas you need to increase pipe size to 3” vent just before you exit so your vent doesn’t frost over.
All of your other individual vents can tie into this main vent.
Vents will slope allowing moisture to go down the drain. Also because vents are flowing air, tee fittings will upside down on a vent only line.
@@markchickenbutt8740 thank you so much for the reply. I'm finally to that part and the advice is MUCH appreciated
Hey@@markchickenbutt8740!
Hard to visualize this process, would be amazing to get some visuals on this.
Vents are sized not by the drain size although it could be a good rule of thumb but sized by the number of fixture units for the fixtures in the system. For instance a full bathroom is 5 fixture units so an 1 1/2" pipe is adequate but if you tie a kitchen sink to that vent it would add 2 fixture units to that and if there are any horizontal runs above that tie in you would have to increase your pipe size. once you get over 10 fixture units horizontal runs must be increased to 2 1/2" and so forth.
I've watched your video many times. Very helpful. I think this gives a home owner the ability to recognize poor craftsmanship.
Fast, concise, clear, visual power, Really great!
Thank you sooooo much!!!
A double sanitary tee makes near impossible to run a snake through it since it goes right through to the other sink and a clean out is not practical since there usually is not enough room. Where I live we use double "Y" or off set the drains. Sanitary Tee's also have a lot of resistance with flow even vertically installed.
Very helpful right now I'm remodeling a shower in my 70-year-old house.
No inspector is involved but it's necessary to make a lot of changes.

I’m an electrician by trade but also a finish carpenter and I can fix anything.
I do plumbing too
Any crackhead can glue pipe together and “ make it work “
But it’s knowledge spitting, like this guy, that turns us closer to craftsman and professionals.
I follow the general rule of only using a hard 90 on vents.
It was nice to learn that they can also be used on toilets too.
Learning about other trades helps us all out and makes us better craftsman.
Thanks for sharing your knowledge!
You do great service to others
Most welcome, please share if you can, cheers!!

@@Got2Learn For sure boss! Also great job on the animation ,did a good doing it yourself.
Thanks a lot man!
In my area, the 2" washer standpipe has been required for as long as I remember (early 90s). Also, they don't allow normal pipe to be used as water hammer arresters. They have to be the bladder type. They were required for washing machine and dishwasher lines.
Drill plates are not always required for plumbing or electric; they’re only required when the distance from the face of the stud/joist to the surface of the pipe/wire is too little.
A simple sanitary T on the flat won’t work for long, especially with toilets as the flow can hit the T and split leaving solids to build up.
The cleanout also works as a test plug for inspection. Most inspectors like their drains filled with water to the top of a 10ft stack.
Absolutely, I should of mentioned this, thank you!
In the area where I live a test stack with 10 ft of water would freeze in the winter Here all the lines a capped and a air gage is used and filled with pressures air and it must hold pressure.
@@timhale501
That is true, but its difficult to test air on a plug. You woud have to cap off or does air work as well?
Learned the difference between short sweeps and long sweeps and when to apply. Thanks!
You bet!!!!
The city of Knoxville TN inspectors have always been tough on handicap dimensions and all the things you mentioned
They were also particular about commercial kitchens especially when it comes to proper venting of floor sinks and floor drains

Honestly, I'm looking toward designing my own homestead in 1-3 years, so coming across this video on my recommended list was awesome! Immediate subscribe! While I'm intending to thoroughly read through the codes and make sure I am up to them in the design phase before even starting buying land and building, it is good to know the reasons why for things that would cause a failed inspection. I did a lot of work helping my godfather (who passed this winter from cancer) with remodeling an apartment building he was a caretaker of when I was younger, and I did plumbing, electrical, and basic carpentry work then, as well as taking an architecture class later. I know what I don't presently know now I can learn, especially with so much information online including the different codes, but it is wonderful to come across videos like that which actually explain the reasoning and show examples. Thank you!
You are most welcome, and sorry to hear your godfather has passed, plumb on my friend 🤘
@@Got2Learn thank you. My godfather had fought his cancer into remission three times before it finally took him. He and my father (who is still alive and he and my mother want to join me on the homestead since we're already in an apartment together) both taught me a lot about practical skills, and gave me the room to try things here and there. I was still in junior high when I fixed a toaster they let me take apart and use a voltmeter on, and replace a piece on a PS1 original with a piece from a thrift store cd player. My godparents and parents may at times have irritated me, as all parents occasionally irritate their children, but they were good teachers of useful skills.
Knowledge is everything.
2 years later you get to design your homestead yet?
@@VitaKet unfortunately, no. The plan was to purchase land and build a small home for my parents, and a separate one for me. However, because they're both disabled and making just high enough to have a spenddown in our state, very few other states are possible for moving to, without them losing medicare. Even moving outside our county would mean a massive jump up in co-pays due to programs here that help... and the price of land is too high within the county for anything that allows residential, let alone the fact that it has stricter building codes limitations than other places we were looking into before, which aren't feasible for them to move to at all. We're even in the cheapest apartment units in town, and yet the price of rent, utilities, food, co-pays, etc, mean that they wouldn't survive without me helping as able. Maybe if I ever make enough to get them set up somewhere that they're on half as much rent to me, or none at all, then I could do whatever separately wherever I wanted... but I'm not about to abandon them when no one else would help.

Glad you think so!!
Get the $15 book on plumbing from the Home Depot and follow the suggestions - I passed every time.
Good description on the plumbing code. The #6 violation, is still a violation. The double TY fitting must be a double Y fitting, this will prevent the snake from passing from one side to the other, if the drain is plugged down stream of where the 2 lines meet.
Frank, i've had that happen before & it led to finding that the stack was packed from that point down. Very unhappy client!
Correct it has to be a double fixture fitting

Other than replacing taps I would never do any plumbing myself but I love learning this so I understand what others have done. I had a new bathroom installed a few years ago with - necessarily - exposed outdoor pipes (I'm in Australia so no issues with freezing). I now know why all the things (e.g. the cleanout) have been installed as I am sure the rules are similar here to in Canada or the US
in my country (easten europe) you do it better by yourself because you don't really have a choice. the reason is that there are no good plumbers and they don't know any of those rules and regulations. the good ones emigrated to western countries and the ones that remained are extremely expensive and not available because they are working for important jobs only (not housing)
Great job and as someone that does their own plumbing in remodeling jobs, I learned the code the hard way, well before youtube was invented and well before AOL...:) But, I only needed once to learn...Thanks so much for putting this up, it's nice to take time out of your life to help others, if everyone did that, the world problems would get sorted out much faster...Namaste!

When calling my inspector for my rough in I take him to Wingstop beforehand. Works every time.

When I was a residential new construction plumber no inspector was the same. We had to remember what area we were in whether it was a city or county inspector. They were all different. Some things were the same. It resorts back to the code book. It says left to the discretion of the code inspector.
Interesting, in my 30 plus years as a codes consultant for over 150 jurisdictions, I never saw any legally adopted code allow inspector discretion. The codes are written in mandatory language; if an inspector claimed he had discretion he was flying blind.
Good to see this again, I'm a plumber but I do more heating and cooling

Regular 90*s can be used on drainage when going from horizontal to vertical, long sweeps on horizontal to horizontal or vertical to horizontal transition
There are a lot of factors here that I just couldn't mention or the video would have been 3 times as long but yeah, there's some places they are allowed and some not, thanks Pat!
I never understood this. Reg 90s on a horizontal position, less bend, but HAVE to use long turn 90s from horizontal to vertical. Can someone please explain this to me?
In drainage they are not called 90's. They are called quarter bends.1/4 bends. 90's are used in water systems, gas pipe, etc.

@@path3848 Negative. Read your national code book. Got my NC P1 master licenses in 2001 and this was a big reason people failed. Not naming fittings properly.

Great video! I have a few questions:
1. If a drain line is going from horizontal to vertical, should a short or long sweep 90° elbow be used?
2. Can a sanitary be used on its back for venting? The vent would serve the kitchen sink (with dishwasher and disposal) and the tub/shower.
3. Can a double sanitary tee (2in inlets 3in top and bottom) be used in a scenario where one side is the inlet for the kitchen sink (with dishwasher and disposal) and the tub/shower and the other inlet is the bathroom sink and a washer (pumping action discharge)?

Thank you for the awesome videos. I recently had to remove quite a bit of a 3 in waste stack to allow foundation guys to repair a structual wall.

And yes I used to have to clear that blockage about once a year. Fortunately there was one clean out.

Some of this is brilliant but others are unheard of in the UK. Like drill plates, over here it is the dry liners fault if they put a screw though a pipe.
Also 2 inch trap and upstand for a washing machine is so over kill especially as it most always T's into a 2 inch float straight away.
I moved from the USA to Norway, where they also do not use protective nail plates. When my house was being built, I made and installed my own and the plumbers and inspector all commented on what a great idea that is. It also has saved me a couple of times both when I installed the sheetrock and afterwards when hanging shelves.
I much prefer preventing an accident over someone being liable for one.
Mr Sam Drywallers here are idiots 😂 Just kidding. Really though, they’re often in such a hurry in new builds that I could totally see someone not marking the sheet for the locations of piping, or not marking it properly, then screwing through a line 😬
As for the 2” standpipe for laundry, I wonder if it’s an appliance thing. Maybe the washers here put out more volume when draining? 🤷🏼♂️
Just imagine if the dry wallers drill a screw into a main copper supply and the screw only lets only a bit of leakage out , you won’t know till you see your drywall getting moldy, the nail plates are just an extra precaution.
@@orboflightning Just looking at how you boys do it over the pond, seems like you run a lot of pipes through timber! Must be loads of holes to cut! Can see how those drill plates come in handy.
We almost always have a void to run pipes, then the dry liners put up sheet steel stud work and then plaster board/ dry wall on top of that. Much less likely to put a screw through a pipe like that.
@@armandopena7921 true. But that's not a precaution that should fall on the plumbers. The drywallers should be doing that, if they are too incompetant to be sure of where they are putting their screws.
So well presented and explained. I love your use of diagrams. Also, I learned about that shock absorber thing from your other video :D Thanks for making these excellent videos!
🤗🤗🤗
Shock absorbers are not required on a class a pex system, but it is on copper, cpvc etc.
Thank you ! One of the best explanation. Short and precise.
Great video my friend, very very informative, every second of your video is very useful, keep safe and thank you very much for sharing,
Thank you so much Bahiano!
You are welcome, thank you

For #6, some codes require a clean out above a double sanitary tee, otherwise when snaking, the snake can jump to the other side of the tee and never be able to go down the stack toward the clog.
That was a double combo
I’ve plumbed for 8 years and have never seen a snake in a pipe on any job. I do run drain cables with drain machines to clean lines
It's a double fixture tee, a double combo creates an s-trap and is illegal.
As a PM keeping on top of codes regardless of the servicer, ie: plumbing, electrical, framing, roofing…is a constant issue, and daily inspections are a must…best just to have high quality contractors to avoid foolishness that inspectors inevitably will derail a project if it’s unacceptable…
Vents lower than flood rim of fixture:-- Although an odd duck for sure, the configuration for an island vent has a workaround for being an exception. i also love wet vents which usually get a knowing nod of approval from inspectors. I don't know your locale but in Los Angeles I stopped putting T&P on water heaters and instead just put a pressure relief outside by the shut off. No more pans or drain issues with old heaters inside closets. Always passed.
Not appreciated enough is the satisfaction of watching a main line stoppage let go, after you've been playing catch and release with a forest of roots, letting it tangle up just to the edge of the cable flipping in the cage, then yanking back, like fighting a marlin; then it goes BOOM like thunder and you may even have to hook the cable up to your truck and pull out a 10 ft tail of magnificent roots. You feel like mounting them as a trophy!
Retired plumbing contractor now, but thinking back, I enjoyed being Roto-Rooter man in L.A. Hollywood more. Every job was an emergency; calls in the middle of the night were like sweeping out of your bat cave, and whether you arrived at a swank Beverly Hills restaurant, a mansion on the hill, or some low rent apartment complex, you came in like a cowboy and everyone followed your commands, rich or poor. flooding sinks from floors above, main lines backing up into basements at exclusive country clubs. But all of them open sesame to you, fair haired hero of the moment!
I am a commercial plumbing inspector for the City of Los Angeles - I LOVE watching your videos. I see these violations ALL the time even though I only inspect commercial which here, also includes new apartments, condos and townhouses where 3 or more units are attached. We can always tell when we the a contractor who "builds high end homes" tries to do a commercial job. It is correction after correction.... We do out best to educate. The "B" does not always mean general!
Excellent video,thank you for sharing..
Crazy how much this stuff changes
You are always so good at explaining everything. I learned a lot
Thanks so much Kev ;)
I love your videos especially how you explain the problem but then go on to explain the implications. Most valuable as usual!
🤗🤗🤗
fascinating. One other point more about the old 18 inch hammer arresters they used to use those dead leg pipes, they end up filling up as the water absorbs the air and fills the pipe with stagnant water that can actually breed bacteria and begin to contaminate your tap water, Also why in any old house I have lived in I never drink strait from the tap, I always only use filters. a 40 year old house, who knows wha'ts in those pipes.
True!!!
A 40 year old house in the UK is a new build.
My home is 120 years old, its not even classed as an old house.
I still have lead water pipes, with a bit of copper. Certainly no plastic pipe.
My friend lives in a 400 year old house with its own well.
In number 10...if you choose to run the pipe below the joists, you should have changed the 90 to a long sweep.
the chart for the drilling through the joist is most helpful. Thanks
Glad it was helpful!!!
I did all the plumbing in my home and past inspection.
Well worth the wait, good animation, and informative.
Thank you so much, don't forget to share Andre!
Everything there you explained was correct my hats off to you that being said you could have a video that's 3 hours long explaining a whole lot more thank you for explaining what you did
