I have a 1951 three level home. I am trying to add a bathroom to the basement directly below the main level bath. I have a 4in stack that I would like to have my new toilet, sink, shower and washer dump into. I would vent all of these fixtures into a 2in vent pipe and then bring that pipe above the highest drain from the main floor fixtures. Will this work?
Eventually I want to add a bathroom on the 3rd floor directly above the current bathroom. Currently the main floor fixtures all drain into the stack and then use the upper part of the stack as their vent. Would I have to do something to the main floor in order to have the 3rd floor bathroom drain into the stack above the main floor bathroom fixtures? I plan on venting the future 3rd floor bathroom fixtures directly through the roof or into the main stack just before the roof.
I have pictures I drew in PDF from
