Part of our kitchen remodel involves the addition of a large window (12 ft) with a centered kitchen sink. How might one vent the sink in this configuration? I could put an AAV in there, but because I have an existing roof vent for the kitchen sink, I'm thinking why not try and use it?
Attached are several drawings that show a vent idea that picks up the existing roof vent.
as drawn:
1-1/2 inch trap
2 inch drain
horizontal drain length is about 23 feet to existing vertical waste stack
horizontal vent run is about 6-1/2 feet
vent penetration through roof is at existing location
Do you think I'd have a chance at getting an exception for the horizontal run that's below the flood level rim of the kitchen sink? Would the cleanout in the attic and the two long sweeps downstream to the horizontal vent run help with that exception? I've kinda got tunnel vision, stuck on only this and the AAV idea… what other options are there?
Thanks,
Stu
