: Problem is, you mentioned UPC on trap arm length and then AAV's. These are not allowed under UPC but if you would have used the IPC which allows longer runs AND aav's, no problem with what he want's to do.

Good catch. If his code allows AAVs it may also allows a longer trap arm. A longer trap arm to a real vent would be preferable to using an AAV if he can swing it under local code.

Being in Illinois I tend to forget about the more lenient codes! The code here is basically UPC so AAVs are prohibited, but I've noticed that the local home centers sell them anyway...go figure.
