So I have old revent and drain lines that I've cut off that were 1-1/4" copper DWV, which seems to be somewhat rare. I have to tie this to 1-1/2" ABS to build a new section for a moved sink.
Question is, what's the best way to do this?
I found some Fernco reducing couplings at the local Big Box, but I heard from the local plumbing plan reviewer that neoprene couplings must be the shielded type (presumably to protect from punctures). Fernco supposedly makes a shielded reducing neoprene coupler, but I can't find it at my local supply house.
My other idea is to sweat on a copper 1-1/4 to 1-1/2 reducer and a stub of 1-1/2 copper and then use a straight shielded coupler. But copper DWV is hard to find too.
Removing the 1-1/4 entirely is very difficult, because that would mean cutting out the tees from the stack completely, and then I have to build the stack in plastic, and then the 3" plastic fitting hubs wouldn't fit in a 2x4 wall, and... yuk, not fun.
What do people typically do in a situation like this???
