I added a curbless shower to an existing tub and Im not sure about the drains. i have two p-traps and the drain stack/ vent are shared in the wall. Do I need to add a 2nd vent somewhere or does this seem ok? I know its only 1.5” abs but the drain stack in the wall is 1.5” and the 2” ptraps wont fit inside the joists anyways.

Thanks for any advice. Just want to sleep well!
