P trap help - how would you repair?
Posted on 3/19/24 at 5:09 pm

So I have an issue with this p trap in our island sink. It was leaking, don’t know for how long. But I went to plumbing supply store and got the replacement parts A & C (they came together). A & B in the photo below are glued together so I didn’t use A from the new piece just C. A was the part that has a gouge in it that was causing the leak so thought I’d be good to go. Now the threaded piece of A marked as X did not cinch all the way up when I screwed it on. I even took the disposal off so I could allow it to pivot as needed to get a good connection with the threads. Put the disposal back on and ran the water. It leaks at X. Not much but any amount is not acceptable. What would you do here. If I need to replace A/B, I’ll haveto get a plumber out because I don’t feel comfortable cutting it out, etc. I’m trying not to go that route as I just replaced a fridge and dishwasher, have to get a tree cut down before it falls on my house, get my termite contract renewed and a few other things. So trying to save money where I can. Is this a DIY repair? Can I just wrap the whole damn thing in some kind of permanent waterproof wrapping?

Did you tighten by hand or with a big pair of pliers?

Holy crap you have a lot of connections. WOW.
My advice. Get a plumber there and cut that monstrosity out and have done right.

Is it possible the threads may be seating at X before a seal can be made at the joint? Was there a washer/gasket with A that fits into the coupling?

Whoa! That’s a different set up. Are you sure you didn’t cross thread X when you put on A? Make sure the threads are the same on A and the X nut. Once I fought something until I realized there were two different thread sizes.
1.) I’d try putting a bunch of Teflon and pipe dope on the threads of A and and try tightening X again.
If that doesn’t work…
2.) Go ahead and prime and glue A and X. Thread it up as much as it will go and let the glue set for a couple hours and see. I realize you’ll never be able to take the P-Trap off again, but it’ll fix it. If that bothers you go to 3.
3.) Cut out the 2” tee and replace with a 2” by 1 1/2” tee, short piece of 1 1/2” pipe, 1 1/2” trap adapter, and normal SJ 1 1/2” p trap and tailpiece to the sink.

Im a big fan of fixing it right if Part A has a gouge, and you can DIY. Part A needs to match Part C thats why they sell them together.
To DIY, you can cut the pipe Part B and use a socket saver / fitting saver to drill out the portion of Part B sticking/glued into the wye/tee fitting. I recently had a plumber do this exact repair. New Part B could be glued in, then new Part A. The socket saver makes a mess so my plumber had a helper hold shop vac while he drilled.

Did you loosen the nut at the bottom of the sink tailpiece? Part C may slide up allowing the connection at x to be tightened. If you didn’t try that, take it apart at x and at the sink tailpiece. Cut off a little of the tailpiece and put it back together and tighten it good at x.

I don’t feel comfortable cutting it out,
well that is where you are at because there is something wrong with the threads on the old one not sealing on the new
but you dont need a 2" p-trap, you need a 1 1/2" p-trap.
home depot and lowes make full p-trap kits with everything you need to connect from the sink down tube to the p-trap and drain line connection
but you will need to remove part A, that 90 from the piece of pipe. but you cut it right up against the edge of the 90 and that leaves you about 3/4" to glue a connection on it with the crush rings so its all easy to take apart again
its all super easy to do and you dont even need any skill, just the patience to cut the pipe and glue on one fitting and the rest is all slip together and hand tighten the rings and its all done
here are the p-trap kits LINK
the reducer to glue onto part B LINK
and the coupling that you glue onto that reducer LINK
and if you need to extend the down tube from the sink to be longer, just use this LINK

The top left is a slip OP, it moves up and down with a washer. Yes you could cut it all out from where B hits A and go 1.5” that whole way with an adjustable p trap kit. That’s the way 95%+ of homes are done.
Work your way from B back to the sink making sure everything is solid. Then make the final adjustment at the part above C.
PS- you already have 1.5” drop from the sink so going wider after that is pointless as that’s your bottleneck anyway.

Is there or should there be a gasket at A-X-C?
Put a something to catch the drip baw. That shite will last decades.

That nut “X” has got to have something under it to seal. It is usually some type of tapered interference fit like a ferrule. Whatever it is, be sure to use a new one. If you have to, dry it out well and smear the tiniest bit of silicone on the interference fit.

Tighten it up maybe use a little lube on the threads

The OG plumber that installed this is who fricked you from the jump. Normally in houses the only thing that needs a 2" drain is a washing machine. If I was coming fix this at your house...I'm either
A.) Cutting out that Tee and replacing it with a 2x1-1/2" tee or
B.) Using a socket saver to remove pipe "B" out of the tee, and glueing a 2x1-1/2" bushing into the tee. You can see the bushing glued in to the top of fitting "C" currently
The fitting that is glued above C is called a trap adapter....it adapts from glue style to SJ (slip joint) to allow you to intall a slip joint trap. It has totally missed its purpose by being before the trap.
The trap adapter would be glued into the Tee where pipe "B" is currently, and all connections after that would be made leak free with hand tight + 1/4 turn.
Plumbing is easy to do but tricky to do right. This would be year 1 apprentice work at our shop. Defintiely do not just wrap it as that will not stop the leak and will encourage mold growth in the warm, still and dark of your cabinet space.
That'll be $175

Silicon right above and right below the big plastic nut. Slide it into the seal with finger tip.
Or, flex seal liquid paint in the same place. It won’t leak and it will come loose if you need to get it off later.
