P-trap Install

[SteveY]

So I was helping a friend replace an abomination of a p trap install (see photos), and I went and purchased everything only to find out the copper drain pipe coming out of the wall doesn’t appear to be a standard size? Now I’m having a hard time finding an adapter to go from 1-1/2 DWV to this copper which is exactly 1-1/4 OD? Am I able to get something for this?

Must be 1 1/4 in the wall,you will have to lower that trap so you going basically straight into the wall what was sticking out of the wall that was clamped to????
How are you connecting to what's in the wall

You can't reduce in the direction of flow. You have 1 1/4" tubular coming out of the wall. You need an 1 1/4" tubular trap and tailpiece extension.

Best would be to soldier a trap adapter on https://www.homedepot.com/p/Everbil...int-Trap-Adapter-Fitting-C9017114HD/204620211

Easy option is a 1 1/4" fernco https://www.ferguson.com/product/fernco-1-1/4-in.-4.3-pvc-tubular-flexible-coupling-ftc150/1445.html

Or if you can find an 1 1/4" slip joint union you can use that.
