Please save the speeches about how "an AAV is the lazy way out"... there is simply no way I can run a proper vent in this space.
That said... I've spoken with several "master plumbers" at the big box stores, and they all said something different. I won't have a chance to talk to my local officials for a few days and wanted to get started on a dry-fit mockup in the mean time.
Here is a diagram of what I'd like to do, what are your thoughts?
I had one guy tell me the AAV won't work the way I have it set up, I had another tell me to use an AAV for each trap.
From what I can tell it looks a *lot* like the Terry Love approved setup in this thread.
The double wye above is not legal. A double fixture fitting yes, a doubly wye, no.

- All lines at 2" PVC
- Slop sink to p-trap to 45 degree street elbow to double wye
- Washing machine to standpipe to p-trap to 45 degree elbow to previously mentioned double wye
- Top of wye goes up to an AAV
- Bottom of wye runs to cast iron via PVC bushing
