I'd like to add a utility sink by the washer/dryer. This is the drain over there. The first pipe (left) is the washer), the middle one is the kitchen sink from upstairs and the third one (right) is the vent.
The bottom of that trap is 10" above the slab and the top (where the pipe connects) is 15".
Obviously I'd like to be as non-intrusive as I can, but I will do what I must
