Not so sure about that, I think there are masters out there that do not have the ability to teach, this guy is not one of them, but I am sure they exist, and that's okay they aren't paid to teach.
Made it clear to a complete novice why the necessity of a vent, the simple straw was a perfect answer as to the mechanics of the air-water function. Than you
An excellent video! Tight, concise, well explained, and you respected the viewer's time by not spending 10 minutes to explain what you could explain in 4 minutes. Bravo!
I’m a master electrician and I thought he explained it well. I’ve never been much interested in plumbing but I’m remodeling the guest bathroom and laundry and after calling several plumbers it’s become abundantly clear that the only one gonna show up to do it is me.
Awesome timing... doing a remodel and I've been struggling with wet versus dry venting. So glad I found your video. Your final plumbing mockup of a master bath starting at 03:15 showing shower, tub, toilet, and two lavs is exactly what I'm doing. As the old saying goes "a picture is worth a thousand words". As already stated by another UA-camr "True mastery of a trade comes with the ability to teach" You are a master!
@@risingtideplumbingConfused Brit here. Is "lav" a sink? We call toilets lavs and I couldn't understand why the water exit point would be waist height 🤯
So far this has been the BEST video on plumbing I have ever seen AND needed! Thank you. Can you please do one on setting up the plumbing before the foundation is laid? I bet you would crush the explanations as you have done here! Thanks again!!!
@@risingtideplumbing cant wait for that one, could you make sure to explain in the video how you determine where you put your stacks and what sizes to use?
Thank you so much for your concise clear explanations. I am doing my own plumbing and offered to pay a retired plumber $50 an hour just to come over and consult with a little guidance he didn’t even return my phone call, but that’s California, a bunch of Prima Donna’s LOL 😂. I will be watching more of your video’s
Best videos! 4 minutes! And learn so much and tying in the whole system, not just one bit of info and we have no idea of why or understanding all the system parts. 🙌
Wasted my time on 7 other videos before yours was suggested. And still I didn't understand how to vent my house I'm remodeling. Boy...I could've saved an hour of my time. Simple, to the point and most straightforward! Thank you a ton, appreciate you taking the time!
Another great video from you! Thank you for describing this so thoroughly at a quick pace that lets me share your vids and use them to plan my plumbing fixes. Just wanted you to know that I appreciate what you're doing here and that your videos let me put ideas into action

Great explanations sir! Thank you! Sadly, we have friends who just bought a house 2 weeks ago and they've quickly found there were sewage drainage problems and possibly other plumbing issues and permitting problems on past jobs. I really feel for them as they don't know much about those issues. An inspector can't find everything plumbing related, but when you see a concrete patch in the garage, my antenna would go up immediately with questions about what was done here/when and was it permitted. They're having a lot of work done now on a home they've been in for 2 weeks... ☹
Finally a fellow plumber that can explain venting/wet venting and trap protection from syphoning. I cringe with some explanations out there, so much bad advice homeowners follow.
Usually all Greek to me, but I must say with your video I have actually gained a bit of knowledge. Who wants to be confused!! No Not I!! Not Just when I thought I had at least a chance of understanding the workings of a plumbing system,...NOPE! Well plumbers of America I say..........You go get it
Great information - clear and concise, with mockups to boot. Thank you. My something nice (within an hour...) - I recommend rotating your camera to Landscape mode. A phone is easily rotated from Portrait to landscape, while my ultrawide monitor is not capable of rotating from landscape to portrait. ;-]
Awesome! Thank you. I’m about to try this myself, instead of hiring the plumber. I might end up spending more, but I’m giving it a try. I could mess up a few times before I reach the estimated cost. I might just do it and be able to help others save a few bucks too.
Thanks! Great video. I am an interior architectural designer helping design my parents' bathroom IN A HIGH RISE CONDOMINIUM/apartment building in Florida. We are on the 3rd floor. There are 4-5 units per floor and 12 floors total. I have worked mostly in the UK and Asia and some US regulations are different based on UPC or IPC. I am NOT an expert in venting or vent stacks but I know we need them. I have read the vent stack cannot be less than 6 feet for the closet flange of the WC/toilet. We had a plumber in for a look and quotation and he suggested our toilet had a vent stack right behind it making a wall-hung toilet and hidden cistern impossible. However, on the architectural plans (not AS BUILT), there is a VS and SS just about at 6 feet from the existing WC toilet. If I am correct and there is only one vent stack and one soil stack at 6' or less, is it possible that the plumber was incorrect? I got the feeling he likes to keep life consistent without change or new plumbing ideas for convenience. But I don't want to misjudge him! We are also speculating on installing a single breaker tankless water heater and he groaned at that. Well, he groaned more at the idea of a whole home 3-breaker tankless water heater. What is your experience with ELECTRIC tankless water heaters in the USA? Nay or Yay? THANKS SO MUCH IF TIME IS POSSIBLE TO REPLY.!!
I’m not sure how this video popped up on my recommendation but great job bro 🤘🏼🤘🏼I’m a UA UNION PLUMBER it’s art to me tbh cast iron solder brazing etc I love it all plus awesome money over $100,000 a year love it
Thanks so much. Let me know if you have any other video ideas that would help. I’m editing the first of a series of videos from the slab through the final of a 5 1/2 bath custom home.
Thank you for making this, it was very easy to understand, -Just curious is there a maximum distance the vent line needs to be?- Never mind you answered it in another video. Thank you !
Pretty solid explanations, although California Code and the International Code has a couple of extra requirements for wet venting, namely. The vent line must be taken off the drain above the cross section and you must increase the drain pipe size by 1. Example: The pipe going to the lav off of the shower would need a 22* or 45* fitting and the pipe from that wye to the 3’’ would need to be 2 1/2’’ or 3’’. The other Lav would only need a 22* or 45* since the tub drain minimum is 11/2’’ an I believe you ran 2’’. I am sure the way you have these fixtures plumbed they would work perfectly, this is just the codes we have to adhere to in my world. Also I have Plumbed in Europe and also own a couple of houses there and our standards are more rigorous to put it kindly. (Licensed Plumbing Contractor for 30 years, retired)
Question: in an existing situation, where the existing copper roof vent is 1-1/2 at the lavatory sink, is it enough to replace the copper with 2 inch PVC up to the vent T, and replace any other 1-1/2 with 2? No fixtures are being added, just moving the laundry from the basement to the first floor. Tub/shower, laundry, lavatory and toilet.
Very clear, thank you! I'm planning to have my roof replaced next year, and am wondering whether it's safe to redirect my plumbing vents to exit under the eaves instead of by roof penetrations. What's your pro opinion on this?
Howdy, I'm the DIY type of guy. Adding bathroom. Toilet on 4" line. Then a 2" wye into 4" line. Total 2" horizontal length of 10ft. Start of 2" will be laundry washer, then shower, finally lavatory sink into 2" into 4" main. Questions: 1) washer need solo 2" line? 2) 1 AAV or 2
My friend of years ago built a structure off county property with a couple bathrooms. Of course he did everything himself and knew it all, you know that guy. All the drains in the bathrooms gurgled even the toilet. It was a wonder he didn't have a full backup. 😁
You rock, Jeff, on teaching to the DIY laymen! I'm planning on adding a standalone shower to an upstairs bathroom that currently has a toilet, lavatory and jacuzzi tub, and based on your comments on wet-venting, would I be okay with this fourth fixture unit install assuming there's a 2-inch vent in place?
In Canada, the wc has to be the most downstream connection in the wet vent. It can be symmetrically connected however it still must be the last fixture draining onto the branch
Kinda a dumb way to plumb. If everything downstream of a water closet is vented, then the toilet will cause no issues. If you're talking a major over a minor, in my area, that would be in the vertical. For example, tying in a washing machine on top of a lavatory below would definitely cause issues.
The water closet is the most downstream on the wet vented branch due to the volume and velocity of the water moving through the pipe after a flush the concern is that it could siphon a trap if the WC upstream of say a tub or shower
Thanks for your video. We are in a new build and will get the sewer smell from the sinks here and there. Almost seems like it’s from the over drain holes in the sinks. Please help.
Thank you for the great video. It helped me a lot. I am doing my kitchen and find information like this about plumbing is great. If you, please can help me to understand how can I plumb my dishwasher?. The problem i have is the dishwasher is not next to the sink, because the layout and the tie space, I have the dishwasher 90 degree from the sink after the corner lazy Susan and another cabinet. Can I plumb it like stand along and vent it straight up to meet the sink vent over the ceiling?
Great simple video... Question: in your wet venting scenario, where does the toilet get vented? You said a 2" vent can carry 4 DFU, and the lav + shower takes 3 DFU. But I thought the toilet itself requires 3 DFU. 3+3=6 which is more than 4. please explain what I'm missing. Thanks!!
Thanks for the video! This helped me a lot! I don't know if you'll see this, and speaking of dry vents - I bought a 55 year old bungalow and I've discovered there is what I suspect to be an old copper 2" dry vent. I was noticing some drips/green stains near the bathroom basement ceiling fan vent cover and on the floor beneath the fan. I saw that there was just a horizontal run of this 2" mystery copper pipe, left uncapped and open right next to the fan body, it was dripping down though the grate. I assumed I was getting condensation from it. Well, what do I know? Not enough! I got a fitting and capped it. Seemed okay for a time. One day much later, heard a loud bang, and big mess from the basement ceiling. So I rip out that section of ceiling, and I see this same 2" pipe had a bend to send it vertical and through a main floor bedroom wall. The soldered bend gave way and dumped what was collecting in this pipe. Today I see in the attic that this pipe goes up into some long cylindrical copper fitting (maybe 4 or 6 inch around) and out through the roof. Would you have any suggestions for decommissioning this properly? I think the only thing to do is remove the whole darned thing, it's likely to attract condensation any way I think about it, and if I cut and cap it anywhere I'll have the potential to trap water that might surprise me again with damage. Anyway, if you happen to see this and have any thoughts I'd appreciate it!
Hey there. It sounds like you have the right idea as far as getting rid of it if possible. If you just cap it, it will just fill with rain water over time. You would just need to make sure that there is nothing else tied into it before you completely abandon it. The other option would be to find a way to tie it into the existing sanitary sewer so it all is connected. Hope this helps.
The 3 inch PVC pipe that feeds into the 2 inch WYE connectors for the lavatory and shower/tub and also is used for the toilet, does this feed into the main drain line via a tee?
you mention around mark 4 that when the toilet flushes it protects the showers p trap. by that you mean it isnt siphoning out the p trap? is that the reason the water closet is always the furthest downstream fixture? thanks and great video
Very good video.. I didn't realize you could oversize a pipe and use it as a wet-vent for other fixtures. I'll share one comment regarding the straw-analogy which is so commonly used. The straw analogy isn't terrible, but its not perfectly accurate, and here is why: There isn't typically a hand or plug over a plumbing fixture drain (unless you plug the drain.. and then there should be no question as to why its not draining), so such a "suction" isn't normaly present in plumbing system, even an unvented section. However, water within a pipe full-of-water does resist changing shape as flow and would therefore suck a P-trap dry since it resists separation (or shape change) in the absense of air to allow separation (or shape change.. ie., taking up more pipe-length and less of the pipe's full cross-section). The primary purpose of the vent is to break this vacuum downstream of the ptrap, to allow air to enter downstream of the ptrap so that the water can settle to the bottom of the pipe, thereby braking the solid-pipe-full-of-water vacuum that would potentially suck the ptrap dry.
We had a large shower install where a roman tub was, we payed to have the concrete floor busted out and moved the drain to the middle of the shower, we have always had issue after the fact, ankle deep in water, when the shower drain is working you can hear the sucking, do you think it is the venting might be clogged or poor drain install?
@@Moondoggy1941 sounds like a clogged drain.. vent problems should only slightly slow drainage if that.. vent issue can cause ptrap to be sucked dry, but that doesn't sound like your problem
Very few of my colleagues in the U.S understand why we vent. Anti science is very strong in this trade and most plumbers will cling to the simplest analogy they can wrap their heads around to explain something in plumbing. Thumb over the straw, (try that with 1.25" pipe) stab a water bottle and it will drain better, (except we don't reduce pipe downstream which is what a bottle represents). Even when confronted with a direct practical test, I've literally demonstrated to my coworkers with capped off vents during new construction that unvented fixtures drain just fine, they still refuse to accept it. Sometimes all you can do is repeat the mantra, venting protects trap seals, and move on.
@@dmills13F thanks.. its therapeutic to hear someone explain something accurately, because its so rare to hear an accurate description when it comes to venting.
Not a plumber but did my own house. I dey dey vented everything as I didn't know about wet . Fortunately it's a ranch, pretty simple but I'll remember if I do more plumbing
Great videos! Just went out and bought a bunch of pipe and fittings to do this. Would you keep the vents at 2" all the way up or go down to 1.5" on the vents?
Nice video. My home is a 1968, with one main vent stack. I have a 1/2 bath with a washer/dryer sharing one room in the basement. Id like to relocate the washer and dryer just outside of that room, and install a shower in their place. Obviously there's some concrete busting and routing to do, but would adding the additional, new washer drain to that area pose any issues? Figure the water lines and electric are currently accessible, so hoping moving the washer/dryer a few feet wont be a total nightmare to add that much needed 2nd shower.
On your wet vent application i have a question. From your first lavatory you had a tee with a riser. Am i correct to assume that that is a traditional vent that turns into a wet vent from the fixture and beyond?
Jeff, thank God ( literally for your videos). I'm good at running water supply lines but not very knowledgeable on the drain lines. I have a small ( tiny) closet size bathroom ( little bit bigger) I'm doing that is about 30 feet away from the main stack venting line/ pipe ( running from basement to outside the roof), do I have to put in a separate dry venting system for this bathroom or can I water vent it, allowing the gases mixed in with ths liquid to travel the 30 ft to the main vent line ? Is 30 plus feet to far? Any code restrictions on this ? Help 😫 !
Roll the 3x2 y at start of wet vent for water closet so the flush doesn’t cut off Use 3x2 y combo with a 2inch st 1/8 bend to get 2/3 above 3inch drain
Just had our roof redone and remembered I had never seen vent pipes coming through the roof. They were not there on the old roof or the new one. I went into the attic over the top of the closest bathroom, and there was only one pipe coming up into the attic. It was terminated in the attic with a special looking cap on it.
Thanks for this video, I have a question, Can I exit my plumbing vent pipe through the attic side opening? I do not want to drill the roof, so I am trying to make the pipe exit through little window opening in the attic, and make the vent pipe terminate 6 inches as per code. Can this be a correct setup?
I have an unfinished attic that I’m finishing. Need to do a bathroom with toilet, shower, sink, and a bathtub. How do I tie-in to the downstairs plumbing to make it work? The down stairs is a slab foundation. Have 4”x6” studs. Two down stairs/ground floor bathrooms and 1 half bath. The upstairs bathroom would be in the middle of the house and the downstairs are on the opposite side outer walls of the house. Is there a email or website I can get direct advice? My floor trusses are 12” the only problem is my span is perpendicular to wear I think I must run the plumbing.
Thanks for a good video. What equipment do you use to trace a cast iron pipe sewer under concrete; what do you use for tracing copper pipes (water lines) under a concrete slab. Thanks
Great video! I am looking to move my kitchen sink on floor 1. Can I simply tee a sloped 2” PVC approximately 6ft long into the current vertical drain coming from directly above and going under the slab?
A couple of times I got drafted to rod out some lines with no prevail talked to friend of mine who is a plumber he told to go up on the roof with a garden hose and shoot in down the vent stack it worked .
Our house had stubbed in for a basement shower vanity and a toilet which I installed and it works fine. If the diameter of the pipe allows it to wet went then I don’t need a vent as part of the system?

Kinda a dumb way to plumb. If everything downstream of a water closet is vented, then the toilet will cause no issues. If you're talking a major over a minor, in my area, that would be in the vertical. For example, tying in a washing machine on top of a lavatory below would definitely cause issues.
The water closet is the most downstream on the wet vented branch due to the volume and velocity of the water moving through the pipe after a flush the concern is that it could siphon a trap if the WC upstream of say a tub or shower
Don’t speak for all of Canada. This is how most of Ontario plumbing is done, excluding some townships that are still old school plumbing code
Thanks for your video. We are in a new build and will get the sewer smell from the sinks here and there. Almost seems like it’s from the over drain holes in the sinks. Please help.
Thank you for the great video. It helped me a lot. I am doing my kitchen and find information like this about plumbing is great. If you, please can help me to understand how can I plumb my dishwasher?. The problem i have is the dishwasher is not next to the sink, because the layout and the tie space, I have the dishwasher 90 degree from the sink after the corner lazy Susan and another cabinet. Can I plumb it like stand along and vent it straight up to meet the sink vent over the ceiling?
Very good explanation!!!
Great simple video... Question: in your wet venting scenario, where does the toilet get vented? You said a 2" vent can carry 4 DFU, and the lav + shower takes 3 DFU. But I thought the toilet itself requires 3 DFU. 3+3=6 which is more than 4. please explain what I'm missing. Thanks!!
Thanks for the video! This helped me a lot!
I don't know if you'll see this, and speaking of dry vents - I bought a 55 year old bungalow and I've discovered there is what I suspect to be an old copper 2" dry vent. I was noticing some drips/green stains near the bathroom basement ceiling fan vent cover and on the floor beneath the fan. I saw that there was just a horizontal run of this 2" mystery copper pipe, left uncapped and open right next to the fan body, it was dripping down though the grate. I assumed I was getting condensation from it. Well, what do I know? Not enough! I got a fitting and capped it. Seemed okay for a time. One day much later, heard a loud bang, and big mess from the basement ceiling. So I rip out that section of ceiling, and I see this same 2" pipe had a bend to send it vertical and through a main floor bedroom wall. The soldered bend gave way and dumped what was collecting in this pipe. Today I see in the attic that this pipe goes up into some long cylindrical copper fitting (maybe 4 or 6 inch around) and out through the roof.
Would you have any suggestions for decommissioning this properly? I think the only thing to do is remove the whole darned thing, it's likely to attract condensation any way I think about it, and if I cut and cap it anywhere I'll have the potential to trap water that might surprise me again with damage.
Anyway, if you happen to see this and have any thoughts I'd appreciate it!
Hey there. It sounds like you have the right idea as far as getting rid of it if possible. If you just cap it, it will just fill with rain water over time. You would just need to make sure that there is nothing else tied into it before you completely abandon it. The other option would be to find a way to tie it into the existing sanitary sewer so it all is connected. Hope this helps.
@@risingtideplumbing thanks for the reply! I appreciate it.
Great explanation
The 3 inch PVC pipe that feeds into the 2 inch WYE connectors for the lavatory and shower/tub and also is used for the toilet, does this feed into the main drain line via a tee?
Thank you.
good info. thanks
you mention around mark 4 that when the toilet flushes it protects the showers p trap. by that you mean it isnt siphoning out the p trap? is that the reason the water closet is always the furthest downstream fixture? thanks and great video
Awesome info, thanks!!
Best video on it yet!
Even your quick mock up of plumbing looks WAY better than the electrical in that building !
Very good video.. I didn't realize you could oversize a pipe and use it as a wet-vent for other fixtures. I'll share one comment regarding the straw-analogy which is so commonly used. The straw analogy isn't terrible, but its not perfectly accurate, and here is why: There isn't typically a hand or plug over a plumbing fixture drain (unless you plug the drain.. and then there should be no question as to why its not draining), so such a "suction" isn't normaly present in plumbing system, even an unvented section. However, water within a pipe full-of-water does resist changing shape as flow and would therefore suck a P-trap dry since it resists separation (or shape change) in the absense of air to allow separation (or shape change.. ie., taking up more pipe-length and less of the pipe's full cross-section). The primary purpose of the vent is to break this vacuum downstream of the ptrap, to allow air to enter downstream of the ptrap so that the water can settle to the bottom of the pipe, thereby braking the solid-pipe-full-of-water vacuum that would potentially suck the ptrap dry.
We had a large shower install where a roman tub was, we payed to have the concrete floor busted out and moved the drain to the middle of the shower, we have always had issue after the fact, ankle deep in water, when the shower drain is working you can hear the sucking, do you think it is the venting might be clogged or poor drain install?
@@Moondoggy1941 sounds like a clogged drain.. vent problems should only slightly slow drainage if that.. vent issue can cause ptrap to be sucked dry, but that doesn't sound like your problem
@@larryzdanis5377 Thanks, I will hire someone with a camera.
Very few of my colleagues in the U.S understand why we vent. Anti science is very strong in this trade and most plumbers will cling to the simplest analogy they can wrap their heads around to explain something in plumbing. Thumb over the straw, (try that with 1.25" pipe) stab a water bottle and it will drain better, (except we don't reduce pipe downstream which is what a bottle represents). Even when confronted with a direct practical test, I've literally demonstrated to my coworkers with capped off vents during new construction that unvented fixtures drain just fine, they still refuse to accept it. Sometimes all you can do is repeat the mantra, venting protects trap seals, and move on.
@@dmills13F thanks.. its therapeutic to hear someone explain something accurately, because its so rare to hear an accurate description when it comes to venting.
Great video! Thanks!
Not a plumber but did my own house. I dey dey vented everything as I didn't know about wet . Fortunately it's a ranch, pretty simple but I'll remember if I do more plumbing
That was a big help.......................thanks
this is so helpful. thank you
Great videos! Just went out and bought a bunch of pipe and fittings to do this. Would you keep the vents at 2" all the way up or go down to 1.5" on the vents?
Thanks!
Well explained! Good Video
You’re a great teacher!
Nice video. My home is a 1968, with one main vent stack. I have a 1/2 bath with a washer/dryer sharing one room in the basement. Id like to relocate the washer and dryer just outside of that room, and install a shower in their place. Obviously there's some concrete busting and routing to do, but would adding the additional, new washer drain to that area pose any issues? Figure the water lines and electric are currently accessible, so hoping moving the washer/dryer a few feet wont be a total nightmare to add that much needed 2nd shower.
On your wet vent application i have a question. From your first lavatory you had a tee with a riser. Am i correct to assume that that is a traditional vent that turns into a wet vent from the fixture and beyond?
Jeff, thank God ( literally for your videos). I'm good at running water supply lines but not very knowledgeable on the drain lines.
I have a small ( tiny) closet size bathroom ( little bit bigger) I'm doing that is about 30 feet away from the main stack venting line/ pipe ( running from basement to outside the roof), do I have to put in a separate dry venting system for this bathroom or can I water vent it, allowing the gases mixed in with ths liquid to travel the 30 ft to the main vent line ? Is 30 plus feet to far? Any code restrictions on this ?
Help 😫 !
Roll the 3x2 y at start of wet vent for water closet so the flush doesn’t cut off
Use 3x2 y combo with a 2inch st 1/8 bend to get 2/3 above 3inch drain
Very well explained. Some close-ups or diagrams might have been helpful but it was very easy to understand.
Just had our roof redone and remembered I had never seen vent pipes coming through the roof. They were not there on the old roof or the new one. I went into the attic over the top of the closest bathroom, and there was only one pipe coming up into the attic. It was terminated in the attic with a special looking cap on it.
Good vid in the fact you created more questions than answers
Very helpful!
Thanks for this video, I have a question, Can I exit my plumbing vent pipe through the attic side opening? I do not want to drill the roof, so I am trying to make the pipe exit through little window opening in the attic, and make the vent pipe terminate 6 inches as per code. Can this be a correct setup?
I have an unfinished attic that I’m finishing. Need to do a bathroom with toilet, shower, sink, and a bathtub. How do I tie-in to the downstairs plumbing to make it work? The down stairs is a slab foundation. Have 4”x6” studs. Two down stairs/ground floor bathrooms and 1 half bath. The upstairs bathroom would be in the middle of the house and the downstairs are on the opposite side outer walls of the house. Is there a email or website I can get direct advice? My floor trusses are 12” the only problem is my span is perpendicular to wear I think I must run the plumbing.
Thanks for a good video.
What equipment do you use to trace a cast iron pipe sewer under concrete; what do you use for tracing copper pipes (water lines) under a concrete slab. Thanks
Great video!
I am looking to move my kitchen sink on floor 1. Can I simply tee a sloped 2” PVC approximately 6ft long into the current vertical drain coming from directly above and going under the slab?
A couple of times I got drafted to rod out some lines with no prevail talked to friend of mine who is a plumber he told to go up on the roof with a garden hose and shoot in down the vent stack it worked .
Our house had stubbed in for a basement shower vanity and a toilet which I installed and it works fine. If the diameter of the pipe allows it to wet went then I don’t need a vent as part of the system?
Perfect time-efficient tutorial! Wow, very nice and brief explanation, man! I just Subscribed!
Thanks so much. More to come.
Great Job, Very educated
Thank you!
