I just got nicked on my plumbing for my sink and am scratching my head on how to proceed.
Situation: House has an existing 1-1/4” galvanized stub out nipple that’s threaded. The existing sink had a 1-1/4” tailpiece to 1-1/4” waste pipe. I bought a new sink that uses 1-1/2” waste piping so I needed to figure out a way to make that work with the 1-1/4” stub out nipple. I couldn't find a trap adapter that had a female threaded 1-1/4" connection and a female 1-1/2" connection...this is what could work.
Below is a picture of my solution. Here is what I did:
The inspector didn't approve of this and said that he would pass me if I got a slip-joint trap adapter. But the problem is is that I couldn’t find a trap adapter that would go from 1-1/4” (wall side) UP TO 1-1/2” (sink side) to accommodate the new larger waste pipe. And I can’t run a new galvanized 1-1/2” stub out because the rest of the galvanized drain pipe is also 1-1/4"
Any ideas?
Thanks

Below is a picture of my solution. Here is what I did:
- Attached a 1-1/2” to 1-1/4” galvanized reducer to the stub out nipple.
- Disassembled a 1-1/2” double slip-joint connector by removing the coupling nuts.
- Screwed the threaded/male end of the slip-joint connector into the female end (1-1/2”) of the galvanized reducer
- Ran my 1-1/2” tailpiece into the other end of the slip-joint connector
