Ok so anyone who was following my last thread, I decided to just bite the bullet and do the submersible pump. Now I'm trying to figure out how to do the drains for these 2 bathrooms. I really want a clear understanding of how I am going to do this before I start. Basically what I have is I split the basement down the middle and decided to do an apartment on one side. Originally I was going to just do the underground drains for the apartment bathroom but it's so much work that I decided that while I'm doing it, I might as well do a second bath on my side of the basement. So I mirrored the bathroom and everything is back to back for simplicity.
What I have:
1) Kitchen sink
1) Laundry
2) back to back bath sinks
2) back to back toilets
2) back to back showers
Attached is a plan of the living space and an isometric drawing of the drains I plan to do. I know the drawing is most likely wrong, but I figured I'd be able to give a better view so someone can correct me or point me in the right direction. After I drew this up I learned that you can't use a double San tee for the toilets and instead use a double Y with 45s. But since it's a basement, I don't think I can do this and have a vent in the center otherwise I'd have to dig down too deep to come out of the 4" main vertically. It would be nice to come off the main horizontally, but I don't think they make a 5way tee with a vent in the center. Again, I know this is wrong, but let's start here, thank you. Also, the kitchen sink drain will be above ground and wrap behind the wall until it gets to the sump and probably tie into the 4" as it enters the sump. The sump is the biggest red circle in the plan.
Please see attached.
