How to Fix Kitchen Sink Drain Pipe Too High For P-Trap
Вставка
- Опубліковано 11 чер 2024
- Did you remodel your kitchen, add a new deeper sink, and now your P-trap no longer lines up to the street drain pipe going into the wall? In this video we will show you how to fix this engineering disaster when your kitchen sink drain pipe is too high for the P-trap.
In this example, we show you a cast-iron plumbing stack inside the wall that must have a section of it removed, then patched in with PVC pipes in order to lower your waste drain pipe coming out of the wall, s that it will line up to the P-trap. Now you'll be able to still install your garbage disposal and dishwasher.

Good to see your worker is wearing safety glasses when cutting the cast iron pipe with his angle grinder!
Awsome work ive watched over 5000 videos on plumbing because i couldn't afford school and now im the top tech at my company.
I love it when the floor is finished under the cabinets. Looks so good
a few constructive comments if i can
1) make sure the cast iron stack is supported before removing it. they can come straight down if not tied into the structure or use of a riser clamp.
2)using a 90 on the horizontal it should be what is called a long sweep, or a code 90. the one you have looks like a standard 90.
3) a clean out is always a good idea. depending on the situation, it can be required.
nice video, for sure it will work.
.
Scott, yes I agree on all 3, except, why need a clean out when you have a 1 1/2" pipe right there?
@@jeffostroff from my experience instead of a double san. tee, they want a double fixture cross. sometimes called a figure eight. the reason is if you run a snake down either side with a double tee, the snake will not go down but go up the other drain. the double fixture is longer sweep, but still has room for the vent to work and direct the cable down. so if using a double san tee a clean out would be a good idea.
i am not sure where you are, but in in Oregon that is preferred.
I always put greenfield hangers i don't know why the guy doing the stack was hitting it with a hammer just use a sawzall with a diamond blade
@@xdghontwitch447 That’s the comment that I was going to make… Lennox makes an excellent diamond blade for reciprocating saws and I wouldn’t have used that grinder. The only time a grinder comes in handy is to maybe get something started but you don’t even really need that either. Get a can of “PB Blaster“ and spray that once in a while when you’re using that diamond cutter blade and it works very well because it helps cool the blade but it also acts like a cutting oil as well. And very lucky that stack did not come down on them specially with a heavy cast-iron one!

@@Doing_it_right_the_first_time lennox blades are decent but in my opinion they are too thin and bend easy i use diamond diablo blades that work great for cutting cast i only ever use a grinder if the space is too tight for a sawzall
excellent attention to detail, gotta love watchin people who take pride in their work
The new drain pipe should’ve been straight in instead of adding a right elbow and cutting the stud to accommodate it. They do have two inlets drain pipes at 90 degrees. My reason being that makes it difficult to snake, especially a kitchen drain that clog often.
I've never seen a waste pipe that big used in a kitchen. Good stuff.
I'd assume the kitchen sink wasn't in that area when it was built. Who knows how many times the kitchen has been remodeled.
I had this exact problem. Every so often my dad would change out a rusted ptrap( metal no pvc). Years later, dads passed, mom calls, sinks leaking! My turn to fix it ! HERES the problem!!!. Did this repair, no issues again
Yes this is a much more common problem than one would think
Next time, and this is just a suggestion, use all shielded bands for your transition fittings. Those ferncos will sag over time and cause issues. This is coming from a service plumber who deals with it all the time.
Weren't those the stainless steel Ben's that he put on there at the bottom and the top?
Theres a "flexible coupling" on top, and another one on the dirty arm catching the sink from the bathroom. The bottom connection is a shielded band, but that one is really only ment to tie in vents. Shielded Bands essentially compress the gasket onto the ends of the pipe, as apposed to just the two hose clamps of the rubber boots.
@@jeffostroff Negative, that would fail inspection. What it needs is an ARC 4 band coupling 4" cast to 4" plastic on top and bottom and all stainless steal bands torqued down to 60. Besides that job well done better then most plumbers ive seen doing repairs like this.
The Fernco couplings are great, I use them, but they are not code if they are sealed behind a wall. They must be either shielded, or you need to provide easy access to the plumbing without cutting through the wall, for easy inspection and repair, if need be. The shielding requirement, I believe, is because of rodents.
Yup, rats and mice eat through the rubber if its not shielded with metal. They get thirsty.
Hats off to all you professional plumbers! I do my own basic plumbing when needed and hate dealing with the filthy water and pungent smell. I see why you guys get paper 💰💰💰💰💰.
Before lowering the existing san-tee/ sanitary tee, strap the vent above the san-tee, to prevent the existing vent from sliding down, through the existing roof flashing down, especially within cast iron vents, weight being nearly inivitable to slide down immediately. Abs vents being light weight, not so crucial, light guage metal P-Tape to strap the cast vent, once san-tee is completed, remove your strap, do yourself a favor from trying to reset existing vent through existing roof flashing once again, also having to reseal vent with henrys tar-sealant. Completely un-nessesary is vent is strapped very first within process.
Good tip
The Jurassic park cut scene was funny as hell lmao perfect phrasing.
I like to incorporate some pop culture every now and then
@@jeffostroff well keep it up
Love your videos
That is some amazing work to solve that problem. I had to do a lot of similar stuff when I remodeled my 1909 house to bring it up to code and redo everything down to the studs. There were *so many* of these weird plumbing choices that had accumulated over the previous 100 years!
I always like a plumbing how to video.
Right on
I love the use of PPE.
Helpful video.
Jeff you have more PPE sanding drywall then the plumber grinding cast iron...he could benefit from your tool giveaways for sure. Great job on all your renovations!
Lots of contractors are like that
Put the dishwasher fitting after the trap
Glad you know how to solve that problem. Goodness.
piece of cake. Much easier if you have your walls gutted during the remodel
I am finishing my kitchen where this WOULD have been a problem but I was lucky enough to run into a plumber at the hardware store who asked me some questions and warned me about this. He said to set my new drain 17.5 inchess below my finished countertop. He was absolutely right and saved my butt.
Genius!!!he is so good , well done.
Thanks, I'm glad you liked it!
Thank you for the video.
I also have the same issues. Previous owner put in deep sink and the drain pipe is higher so they put a negative pitch on the drain pipe that runs through two cabinets.
And they also skipped in the primer, so everything i need to remove from the wall pulls lots of paint along with it 😂.
Good job.
That’s the cleanest cast iron I’ve ever seen. I assumed it’s old because of the caulked joints. Next time use try a side inlet tee so your stub out remains centered. My only criticism is that you called everything below the stub outs a wet vent. Unless there’s a drain below those two, it’s not a vent. It’s just a drain.
Yes good point on that nomenclature
The man using the angle grinder relied on his safety squints. Eye protection is cheap and necessary.
"safety squints", never heard that before, I'll be stealing that
@Janet Yeoman No need for safety glasses if you have fast reflexes. When you see a metal shard heading your way, simply duck your head to the side to avoid the oncoming projectile.
No respirator either
And no gloves!
Spend a little now or pay HEAVY later.
Exact FACTS..
Outstanding video
thanks adam
Nice remodel
thanks, glad you liked it!
Great Job. Thanks for sharing.
I had this same scenario in a new 10” deep SS sink with disposer in my 2nd floor Condo. My problem was putting the plumbing together without a leak, 3 hours later it still dripped. I had a friend Peter that was a high rise plumber (Chicago downtown was his turf) and his specialty was drains. He came over to help me and in 10 minutes we were done. He asked to get all new parts and as many different combos I could find. When Peter inspected the setup, he said he had repaired worst one’s than this. This setup was identical to the one you have. First thing he did was to reverse the trap, picked all the parts he needed and when he put everything together, he assembled all joints with Teflon tape and Teflon paste. He said this always prevented comebacks in difficult situations. It’s been over 3 years and everything works perfectly…….this is a rental unit in a Condominium complex. Thanks….Jim
That's amazing that Pete got it working by reversing the trap, normally we are not supposed to do that, but if you can do it without busting into the wall, and it works, problem solved
Nice work!
Thank you! Cheers!
Very detail video I like it. You are the best In youtube video
Thank you so much 😀
Wow! Thank you for this excellent educational video of having to work with cast iron and merging PVC to it. What a nightmare. Your plumber guy was fearless working that close to the copper lines with that angle grinder, impressive. Carry On.
Do NOT follow this hack work. The used the wrong tools, no PPE, They didn't strap the above cast-iron. Someone could've easily lost a finger. This should be removed from UA-cam.
There is a fine line between bravery and stupidity......
Thanks for sharing, I like to watch the retro fitting on cast iron. That was a good price on the plumber, worth every $$$. Could the plumber have use his chain break to cut the pipe?
I forgot to ask him if he had one, but also other eight not have been enough room to get it in there. That lever arm on the chain cutter takes a lot of space.
I’ll have to share some pics of a job I just worked on last week! Same exact situation but it was caused by somebody who didn’t know how to rough the drain in, hahaha and you are correct for one that high you can’t do anything but drop the Santee
Yes we inherited that height from the builder in 1946 who planted that cast iron plumbing stack and the street drain pipe 22" above the floor. The house never had a dishwasher or garbage disposal before, nor could it have worked. I engineered it so that now they could have a garbage disposal and dishwasher.
@@jeffostroff as soon as I saw that stack I thought ohh poor Jeff hahaha I’m sure they thing was fun to cut! If you didn’t snap it I can imagine you’ve still got the taste of cast iron in your mouth.
Great job though love how you do things correctly.
I changed my Disposal a while back and now the sink drains very slowly when there wasn't any drainage issues preciously. Typical US 3k sqft SFD with 1.5" standard Ptrap. (No other plumbing issues in the house.) Any ideas why? Some things I've found says the drain pitch could be off; another says my brand of Disposal has a poor rubber guard. If I open up the rubber guard a bit it does bubble and go a little faster but I"m not sure it still drains as fast as it did previously. Thanks for your videos.
OMG I'm glad that's not my problem.
Second *jeffostroff* video watched... EXCELLENT! So many small tips of the trade along the way--right to the end of the video--equals SUCCESS.
I almost had to do this for my sink the old sink was shallow stainless and had a tiny disposal we put in deeper black resin sink and giant disposal wound up just barely enough drop to wall. i had a y in there horizontal originally that did each sink separately out of copper, but it got eaten away over the years so now have both sinks tied into each other like you did in one video but mine was just horizontal no downward slope i actually liked the y better had more drop on each sink then
Good video! I'm the type that would have just left the drywall screwed in for easy access in the future.
We have an access port on that wall over to the right
Good job Milwaukee
More owners remolds and designers are dumping disposals as a result of major sewer problems eventually causing backups of main line. I disconnected mine some time ago. Installed quality strainers and dump organic in compost or garbage. Many Highrisers are doing same…
yea people abuse the disposals and put to much stuff down them. My mom put potato peels down there and clogged the main drain pipe 85 ft away from the sink. SHe learned her lesson. NO food down the disposal I told her...
Great video!
A contractor installed the kitchen sink drain pipe 23.5” high from the concrete floor. The cabinets are laminate counter top and I think they height 36”. Would I be Ok by installing a 7” deep kitchen sink or I am in trouble? Thanks.
I've lowered a few drains in my day but I've never paint behind the cabinets. You must be a neat nik!
Whenever I can get to that area, I hate seeing all the handyman patch jobs with tape around the pipes, I like a nice perfect brand new look when I am done.
You are hired. 😮 you are the plumber everyone needs, no shortcuts.
Great work I didn't know you could do that. I learned something today. Thank you
Yes and you can do it too now glad you liked it
nice video thank you I would like to share experience . Drain pipe was to high added extra 90 to connect and for like 1.5 years that sink always drained slow. thought it was clogged used draino snaked it out still going down slow. Finally realized I had created a double trap and that was my problem. Cut open wall lowerd drain pipe and all good from there
Yes this is a very common issue.
Diablo carbide sawsall blades bub. Game changer....
Jeff good job
Thank you James!
Nice, I always like to put a rag when I'm working on any size drain, don't want pieces of material falling in and catching material and clogging pipe in the future.
He should have just used a better Milwaukee Torch blade or something when cutting, then he would not have had to hammer and chip the
@@jeffostroff correct, maybe that's all he had available, the proper tools and/or equipment always make a big difference.
I had to raise it by 3". The original person who did it, put the cast iron drain on a couple bricks. Somehow it must have slipped off and it resulted in a reverse slope. 50 years later I had to go inside the plaster wall. As soon as I opened it up I just groaned.
I had to rip out a brand new soffit on the floor below, where I had put in brand new cabinets a couple years before.
So much work.
Yes and what an incredible feeling when you're finally done and it's working
God bless!
What a problem. Kudos to plumbers who can handle a mess like that.
Another day at the orifice for him
Ahh, the joys of remodelling.
This was a fun project, and made for a great video to help many others in this dilemma
Garbage disposal is expensive maintenance (6 months to yearly plumber calls to unplug.). Strainers are the way to go, I'm not lazy as i wash dishes by hand.
You're right. I throw my garbage in the garbage.
My remodel kitchen is almost completed at cost of $30k Now co plumber tells me drain is too high for the tailpipe with dishwasher. Also upgraded to a deep 10” sink. He wanted to do some weird stuff. like running dishwasher hose thur the drop ceiling to the utility Sink! I said no way so he put the tailpipe with dishwasher hose on drain first then he ran the p trap. I pray it works the water in sink drain goes down slow. I hope they both drain efficiently once power is restored to dishwasher.
You may have to do what we did here
Late to the party but I would have shot that drain fitting over a few more inches to get it from behind the disposal. I also would have changed the bathroom sink arm while I was in there. It's old copper. It's going to fail eventually. Might as well get rid of it and replace it with 1 1/2" PVC before closing the wall up. It would also make your drain fitting less "busy".
Great video, a boost to my DIY skills to tackle this problem in my kitchen,
Hopefully you have pbc and not cast iron
Hopefully not. This plumber is completely clueless
I've used the Milwaukee Torch Carbide Blades for cast iron for the reciprocating saw. It cuts like butter and you can have a straight cut.
I think these eight be the blades we saw Vince from VCG Construction channel testing at the Milwaukee trade show a year ago
Great video and great editing with the Jurassic Park clip. Lol
Thank you 😁
I had this scenario on a newly purchased utility sink. Raise the sink legs (or sink base cabinet), get a shallow sink, or bust into the wall like what you ended up doing.
The choice is, do you want that added luxury of a deeper sink? OK, then it's going to cost you.
Use the Milwaukee torch blade for the sawzill recipro saw. Cuts through 4” cast iron like butter. You can start the cut with an angle grinder.
Is there any type of fitting with the connections that you used and a third connection for a clean out? It seems that if you need to snake it out in the future, with such a tight working space, a clean out might be handy. Thanks
Any decent plumber can easily sneak this out through the peak through the P trap. But they did have a blockage and here a few months later and the plumber was able to get to it from the roof And he sneaked down through the plumbing stomach into the sewer where there was a backup
Thanks for the reply! I was asking as a do it yourselfer, trying to avoid a plumber if the clog was just a simple clog right behind the wall, not in the sewer yet, something reachable with a 20 ft snake.
@@mtbuddha2003 I have always had bad luck with blockages in the sewer because they are always beyond my 20' snake reach. So I always end up having to call in the plumber to bring their sectional machine which they keep feeding in 10th foot sections usually about 30' to 40' before they find the clog down the clog Is down the sewer line
@@jeffostroff When I lived in San Diego, I had the world's best apricot tree right at the back of my lot. My sewer line got plugged up, and since there was NO cleanout, the plumber was up on the roof feeding snake. He was out at about 190 feet, I think - I know he was on the last section of snake he had - before he cleared it. His advice was to cut down the tree, which almost certainly had roots in the sewer, but the fruit was much too good to do that. I told him I'd be willing to pay him to come out every year, and as it happened, I moved before it was necessary again. At least it wasn't beyond the limit of his machine.
Can you explain why you didn't need to install an AAV? My dad thinks I need one. Mine is plumbed similar to this. Directly in to the stack. The only difference is that it's about 15 pipe feet to the stack.
Great video…do you know why this was installed so high in the first place? I’ve been trying to find the answer to rough in dimensions and there are so many piece of crap fake websites out there that are saying the drain has to be 20 to 24 inches high.
what do you do when you wall everyting up and the screws on the strapping rust off and it starts leaking from all the humidity and rust? do you want itl the water finds its way
great video Jeff, I love to see some Ryobi tools:)
Thanks Smitty!
Is the hole on the right bottom side for a dishwasher attachment?
8:34 What was that stud on the left holding? Just a drywall nailer, or weight bearing?
Jams pasarías inspection en California usando esos couplings de goma sin cobertura metálica y sin soporte en la pipa de 3” pulgadas .. pero como siempre es bueno trabajar y eso te hace una buena persona eres. Bueno solos agüérala mejor por si se llenara de aguas negras o templara
Great video! I just got my farmhouse sink in and it looks like the drain coming out of the disposal and the drain going into the wall will be at the same level. Will this work or does the disposal drain have to be higher than the wall drain? Thanks!
I did this once at one of my condo flip projects where they were both the same height and luckily it worked. You simply won't know until you try it whether it's going to work or not
Could you turn sink 180 to put drain close to front to get more room for disposal???
Thank You ...I just went thought this very seinario ... fortunately I have a basement... so I ran a new pipe and joined it to the original drain pipe in the basement...and just plugged off the pipe though the wall...
Great idea
Seems like a lot of work to remove a great piece of cast. In England we would have drilled a 2inch hole in cast pipe low level then put a cast boss in with 2inch bsp
Lennox makes an excellent diamond blade for reciprocating saws and I wouldn’t have used that grinder (yes, better than the Diablo brand blade for a cast-iron by a long shot!). The only time a grinder comes in handy is to maybe get something started but you don’t even really need that either. Get a can of “PB Blaster“ and spray that once in a while when you’re using that diamond cutter blade and it works very well because it helps cool the blade but it also acts like a cutting oil as well. And very lucky that stack did not come down on them specially with a heavy cast-iron one!

I saw one of the Milwaukee Torch or Wrecker blades last year slice through cast iron like butter
Beautiful work.
Thank you very much!
@@jeffostroff You bet.
It could have been done this way because he didn't want to show unsafe practices on his channel, but I would have taken the shield off my grinder and put a 6 inch cut off blade on it. I never had a seven inch grinder but that might have helped here. Also I would have used a reciprocating saw for any that I couldn't cut through with the grinder. Except I never solved the problem of reciprocating blades hitting the back wall if the back wall was too close. So I might have been stuck for the last bit at the back with cutting out a slice and cutting the last bit of the pipe with the grinder.
FWIW, I clicked on the video to see the magic trick way to fix this without tearing everything out. I was disappointed that there was no magic trick. Still a nice video and fun to take a trip down memory of my days working on an old apartment building.
Great advice from what apears to be a plumber below my comment on attaching the main cast oron pipe BEFORE you cut it as youu can have a possible 300lb main pipe that would want to fall and rip out the piping above your cutting area. 12 more man hours added, what a PIA fix, but it had to be done.
I don't know if you don't have access to a proper plumbing supply house in your area or not but I would have used a reducing san t with a right hand side inlet to catch that lav. Would have made it a little less tight.
I thought the upper portion of the cast iron pipe would fall down. What is holding it up?
I have this issue but I was gonna run p trap and garbage disposal drain through cabinet floor to garage then a Wye to main stack. And cap off existing line in the wall
I've missed a few roughs... But that is ... Real, really high
Show these folks how it's done Jeff 😎🛠️😎🛠️😎
Always willing to help!
@@jeffostroff thanks Jeff😎🛠️😎🛠️😎
Ugh. I just had a disposal go bad and had to replace it. Prior to, when I had put in a new kitchen sink, I had to juryrig a straight pipe from the disposal to the drain pipe. Which the drain pipe had been elbowed to the side to miss the copper lines that were directly over it, so the T-joint is only an inch or two below the outlet from the disposal. And honestly, it was the most unnecessarily convoluted setup... like, just T-joint it lower than the pipes, is that so hard? But anyway, I wound up having to slant my P-trap and turn it back on itself, because I couldn't have the disposal outlet facing the drain pipe, so the pipe has to come around on a 180 anyway, and then the P-trap had to slant back so the drain pipe end raised up to fit.
Remodeling and repairing is such a joy, sometimes...
you should try diamond blade in Sawzall it cuts pretty smoothly through cast iron
I know Milwaukee had a blade that they were showing at 1 of their trade shows last year that cut through it like butter I don't know if it was the wrecker or not
@@jeffostroff yeah i tore out some old cast iron the thick metal cutting tooth blades cut it fast they say but it is hard to hold them in tight spaces the diamond abrasive blade for cast iron does not cut as fast but is smoother
Really easy 🤔
Only took a couple of hours
Can you please make a video of the Vector utvs at Home depot?
Nice work but .... the most expensive disposal ever. Wow. Someone really wanted a disposal.
This is much more common than you think many people remodeling their older houses that have a higher placed drain line going into the wall are faced with this decision decision period of course it's a lot easier to do it when the walls are open During the remodel instead of afterwards that was just a few hours of work
Another way would be to drill hole through stack at front, fit flange with Ferropre, and block old connection. Faster and less to change. No perishable connections in the wall.
Excellent job Jeff .You did it exactly like a qualified,good,plumber, would do it! Awesome job!💪
If the contractor doesn't start wearing safety glasses, he's going to lose an eye; if he hasn't already.
You saying “by the grace of God” is why I subscribed! I’m a plumbing contractor and blessed. May Lord Jesus Christ bless you
Welcome aboard my brother
Satan killed less and didn't promote rape... just sayin
What a royal pain in the ass to complete. Well done Jeff on a tough project!
Yes, sloppy, but it works
I am glad the after you cut out the CI section that the pipe above the cut out did not drop. You must have installed a riser clamp or plumbers tape and I missed it. Or damn it Jeff, you know better than that.
That vertical plumbing stack don't forget it goes all the way through the roof and pops out on the outside but on the outside but it is sealed all the way around the roof on the roof with sealant that is strong enough to hold it
Beautiful job
Thank you! 😊
Everybody looking at this video was hoping it was an easy fix this guy removes the whole countertop and cabinet shaking my head
Where I come from we use a chain cutter for cast. And if you’re gonna go through all that work, plumb in a clean out.
Take a look at Moen garbage disposals, they're much smaller diameter and have solved several tight installes for me.
Will do thanks!
Couldn’t you attach the bathroom trap arm on its own fitting on the stack, below the kitchen fitting? In other words, the kitchen trap arm enters its own fitting on the stack, at 16” AFF, and the bathroom fitting enters tts own, separate fitting on the stack at, say, 10” or 12” AFF?
Should've just plugged it, then came below it with a cast iron chain cutter and cut out a small section where you could then install a new tee using two hub bands. Would've been alot easier. Or even just went through the floor and tied in under the house and used the old line as a vent using a tee which connected the line above with the new line tieing under the house (kindve like a vent loop).
No disrespect but you could have cut through that cast with a long carbide sawzall blade in minutes with a near perfect cut
That's what I told plumber I mentioned new Milwaukee torch blase to him but he did not have one.
That plumber was and is a hack.
On second thought I would definitely rent the cast iron pipe breaker it just doesn't pay to go through all that it's really too much and the cast iron usually gives you a nicer cut if the pipe isn't too rotten
About how long do those rubber boots last??? Very interesting video!
No idea, hopefully decades
