I'm planning to add a bathroom to my basement, but struggling for a good layout. As you can see from the attached layout, I have two 3" stacks coming down from the first floor. I'm ASSUMING its a straight line from the 1st to the 2nd (running right to left in the pic). After that, I have no idea where the pipe goes. Also don't know if the pipe grows to 4" somewhere? I do have access to underneath the stair landing, obviously with limited headroom.
Any suggestions for a good layout?
(Venting is another challenge - only vent to tie in to is the 1 1/2" one at the laundry sink. But I have to cross under the stair landing, at a height of ~ 42")
Code is 2015 IPC , according to town website (not sure why not 2018 yet, but anyway ...)
