AAV Shower Question
I'm installing a shower into a master bath I'm working on in my attic. The shower is too far from my waste stack and other fixtures to tap into any venting on that end. To vent the shower traditionally is going to be a major problem. My question is whether what I have planned with an AAV would work. I'm looking to run an AAV in a stud wall for a closet (with vent for airflow). I'm in PA and AAVs are allowed by code. I've included a (crappy, approximate, and N.T.S.) diagram with what things look like. My trap for the shower is so far away because there's a raised ceiling just below the shower area for about 4 feet of the run. Thanks!
