I'm plumbing a new bathroom in an old house. A really old house. And since it's made of brick and plaster I decided to vent using AAVs instead of tearing up plaster walls and ceilings to get to the stack.
I'm getting ready to tie the shower drain into the main 2" branch that the bathtub and sinks connect to. The shower drain is about 2 feet away from the wall where the AAV will go and 2' in the other direction from the DWV branch.
I'm considering 2 ways to plumb it.
This way is obviously simpler but I believe that's what is called a wet vent which I guess is frowned upon.
I believe this way is a "dry" vent but to me seems like it would have less flow since it's 4' more pipe and has 2 more turns in it.
I'm obviously a DIYer but I do want to do this the right way. Thanks all!
