When I bought this house it had an unfinished upstairs bathroom which I am now going to finish. The 3" drain line runs down the first floor wall into the basement and then connects to the 4" main. I can't change that vertical drop to the basement as it's behind the finished walls of the first floor.
I put together this mockup to show what my plan is on hooking up a toilet, shower and sink in this upstairs bathroom. This will all be below the upstairs floor, inside a 2x8 floor joist so I don't have much space. Everything does fit though and has the 1/4" slope per foot.
Is this sanitary tee the right one to use? Does everything else look ok? The only thing I thought I might change is to add a cleanout at the bottom of the vent (which is in an accessible kneewall).
Thanks very much!
