Alright gents,
Wife has me remodeling kitchen. Old sink was in the island, now moving to interior wall. Most plumbing lines on this wall already. My question is which line should I tie the sink drain into and then do I need to run a separate vent?
I’m a Fire sprinkler guy but have almost zero plumbing knowledge. I’m assuming the 3” line (middle) is the main drain/sanitary line. Originally I thought the 1.5” line (far right) was a drain line as well due to the clean out present but then started thinking it was sized to be a vent line?
2” (far left) really not sure but assume may be drain line for washing machine upstairs or another part of vent stack.
Current plan is to cut in a tee to 3” line and just drain sink into that. Do I need to tie it into a vent line? Just add an AAV?
Any help appreciated!
