i accidentially put this in the shower and bathtub section first. sorry. this seems more appropriate. thanks.
ok i attempted to attach a plan drawing of the bathroom to make it easier to understand.
the circle at the top is the main plumbing stack a 3" pipe (it switched to 4" after going under the slab and turning 90 degrees) that under the basement slab turns away from the planned bathroom wall at about a 45 degree angle.
i have cut out the floor to expose the drain line and the area for the toilet.
what i.m not totally sure on is how to vent this set up.
2 things need to drain. the toilet and the lavatory sink.
i plan on the toilet going and tying into the main drain at a 45. i wanted to bring the sink drain through the wall and turn 90 (down) and go into the toilet drain.
how do i vent this?
can i put a T in the sink drain so that when it goes down the vent for the sink and toilet go up? can they then turn over into the plumbing stack and be considered a wetvent. or can i put an AAV on a toilet vent? do i need to run the sink drain past the toilet vent and go all the way over to the main stack?
any help would be much appreciated. thanks.
