Plumbing – Tailpipe of sink not aligning with P trap


The tailpipe of the sink is about 1" behind the P-trap. It's also too long. If I try to jury-rig it and force the connection, it throws everything off including the vanity top.

I can probably cut the tail pipe, but hope it's not necessary to cut the P-trap/drain because it's all pretty permanent. I probably could cut above the P-trap if I really had to.

I've watched numerous YouTube videos and tried to make this work, but I cannot. The male thread piece on top of the P-trap seems off, too, because every nut/connector is loose. I bought a Snappy Trap assembly, thinking the smooth-sided flex pipe was what I needed but I can't make that work either.

It looks like you have 1.5" pipe there, and, for some odd reason, someone decided to convert it to 1.25" right off the sink drainpipe (and with glued PVC to boot). This makes for some frustrating work, especially, if that drain ever gets clogged (good luck getting into that P-trap).

I would make the same cut Michael Karas made on the pipe coming out of the wall, but I would downsize to 1.25 at that point and install a standard 1.25" hand-screw trap. You can glue this convertor on and then buy a PVC P-trap kit (you will likely need an extension pipe cut to size to make the trap reach the existing drain).

1.25" convertor

The new tail piece screws into the adapter and can be moved back and forth as needed to ensure you line up with the new drain. And all your connections are hand fittings now, so drain maintenance is far easier.
