Will this drain? (AAV in island)

[fateshand]

Hi,

I just remodeled my kitchen and we tore down a wall and replaced it with an island. So we took the main vent line out and I'm trying to replace it with an AAV. The problem is the space under the sink is really tight. So I'm having to really use a lot of pip and 90-degree turns to get the line to connect to the AAV and then to the main drain.

Am I crazy, or will this actually drain without any problems:

I very much appreciate your thoughts and feedback.

You can get a straight outlet for the disposer, which will allow you to raise the trap more and increase the pitch. The fitting cut in for the AAV riser should be a wye, and should be turned so that the flow of air into the AAV is going towards the wall. (It appears you have a sanitary tee on it's back and facing the wrong direction.)

Rather than two 90s coming out of the disposer you should have used a straight piece to go across to the tee on the other side.

I would have had the AAV near the wall.
We use a straight piece between the baffle tee and the disposer.

That is a real Kludge with two 90's out of the wall and then two more back to the sink.

I'm looking at a 7" screen; I did not notice that horizontal run in the back when I posted this morning. Seeing it now, my advice would be to start over.
