Hi all. I've read a few threads on the subject and have a question not covered in those threads. Even though AAVs are allowed here, I'm doing this from scratch so I'd rather do it the better way, assuming this is better. Going by this common diagram...
My floor joists run the other direction. I'm doing this inverted U in a 5.5" space behind the cabinet (I put a 2x6 flat on the floor between the sink base and the cabinet behind it just for plumbing/electrical). So it needs to be just as shown above the floor, but below the horizontal runs to the vent and drain will head towards the front on the sink base. How do I change this, assuming the 45 connected to the T in the drain below the floor is rotated 90?
In case it is relevant, the horizontal drain/vent will run about 8.5', then make a 90 and run another 11' or so to reach the main vertical drain (stack?) and vent.
Also, could someone name those Ts to make sure I get the right ones? I think the 3 upper (vertical) Ts are sanitary Tees, and the 2 lower horizontal ones are Wye Tees. Correct?
Finally, I think the horizontal drain needs to slope 1/4" per foot, but how important is it that the vent be sloped? Since both are running to the same area, I thinking the best I may be able to do is near level.
