I have a base cab and will put a kitchen sink in D/W next to it. There is no way to run a vent to the roof without putting it outside running up the wall. This is my new idea. There is room in the wall to put the following set up. This is an old house balloon frame but fire stops and hard to send a pipe at this exact spot up to the attic. So how about this? I would put the drain pipe in the wall behind the sink send it down to the waste stack and put an AAV in the wall with a nice decorative wood grill to allow air in to the AAV and have access to replace when needed (I say when not if)
look like it will work with a 2" pipe or maybne should be 2.5" drain pipe.
So I am essentially creating a P trap from an S trap using the AAV as was suggested in an older post...
I am not a pro, but what you want to do looks much like what I did for my kitchen sink vent, except that my AAV is inside the cabinet, not inside the wall. The inspector had no problem with it. But then, AAVs are legal here; they are not in many places.
thanks for the input... what I was told on this forum was the AAV has to be above the floor rim otherwise it could leak if there is a backup and it would leak into your cabinet you might not see if leaking and that could cause a big water damage mess.
So this way the AAV is above the floor rim and should be ok even if the sink backs up
