Hello and thanks in advance for checking out my "little" project! Here is the overall plan with dimensions:
I am moving two bathrooms from the South to the North side of the house. They will be back-to-back with a 2"x4" wet wall (non-bearing) between them. The joists (2"x10") run perpendicular to the wet wall but there is a full basement so access and altitude are not a problem.
Here is my first draft of the DWV based on my best understanding of UPC code:
A few questions:
- Is it appropriate to run 2" drain everywhere above Lav #1?
- Can the shower and tub revents be 1.5" so I don't have to butcher the wall studs
- I am planning to wet vent both toilets below all the other minor fixtures -- is there a better option?
- Could I use an AAV on Lav #2 in order to avoid another roof penetration?
Many thanks!
