Forum Title: Seeking help for second floor addition drainage system
Hi Guys, I am about a month away from starting to plumb the waste lines for my new second floor addition. Attached are the waste line schematics and the second floor plan. Does anyone have any recommendations on how to go about tackling this job? Where would you located the 4" stack pipe. Also to note, this house has a full unfinished basement. Thanks, Pat

got a structural print? which way do the floor joists run? what size are the floor joists? where is the waste stack in relation to the floor plan? looks like you have plumbing on an outside wall, is the wall sitting on the rim joist? is this house in a cold climate, outside wall plumbing is a no no if you live in burrrrr cold not against code, against common since

I am located on Long Island, NY. The floor joists are 2x8's and they are running perpendicular to the exterior wall. The waste stack can be placed anywhere at the moment. I was thinking about placing it in the wall between the bathtub, sink vanity and the washer machine. Talked about the outside wall with the architect. It is sitting on a double LVL beam. He recommended that I build and furr out that exterior wall. This way I can insulate the exterior wall and then we would have room for the plumbing. It would also allow me to run the plumbing up with the LVL there. There is room to add onto that exterior wall. I look forward to hearing back from you. Thanks, Pat
