I have a utility sink with a 1.5" trap going into the wall. Right below it (and about 6" above the floor) is a 1.5" cleanout. All the drain lines are cast iron.
Before I start tearing out drywall, I wanted to know if there is going to be a 2" line right under that 1.5" cleanout, or if it opens up from 1.5" to 2" under the slab foundation? I don't want to jackhammer out the floor or tear apart the plate to tie my standpipe into 2", and I don't want to tear open the wall if there's no 2" above the plate to tie into either.
Any insight would be appreciated!
