How to add Utility Sink and Washer Drain to existing 4"

[obriendigital]

Hello,

I am trying to add a sink drain and also a washer box. The black lines in the photo show existing infrastructure. I would like to install a sink and washer box. I am assuming I will need to cut into the 3 to 4" section with the cleanout and install some sort of T with a 2" out to the drain for the sink and washer. Where do I put the P trap or traps and also where is it best to vent. I also have a 2" pipe on the other side of the wall that could be accessed overhead for a vent. Could someone please help draw this out for me? Thank you!!!

That existing pipe... What drains down through it?

Kitchen Sink Maybe?

I sink on the other wall for a bathroom and I think it's a vent too

Do any fixtures from the floor above drain down through that pipe?

In others words does water ever come down that pipe you are planning to tie into?

Yes, i did find out that 2" is a drain. Darn!

I also have a photo of the new cleanout and T to put into the 4" to 3" stack. Is this ok? The 2" will run around the corner to the sink and washer.
The other photo is ultimately where I want the sink and washer.

Lastly, there are a couple photos of the stack towards the ceiling, it looks like the left part of the Y is the main vent, can I tie into that with a saddle or 3" with 2" out to 2" then over my wall to work as a vent?


**Note, the photos got turned somehow. The last 2 should be rotated as the stack goes up to the ceiling.

Sorry I meant to say 3" in my post above...

Your 5th picture is turned and missing the labels you had on it over at Terry Love's

No you can't use a saddle on what you think is a vent...

I'm pretty sure that something drains in that too!
What does?
