I am looking to add 2 bathrooms upstairs, above an existing one. I plan for the toilets to be back-to-back (or nearly). I live in a land without inspectors, but would prefer to do it "right." Can someone please tell me if a 3" stack is enough, and maybe draw me a picture? P. S. Venting is easy, dropping is limited. :wall: Thanks!
