Hello all.
I have been searching this forum and the internet and can't find a solid answer and hope you can help.
I want to put a 1.5" horizontal drain for a double vanity sink from one bathroom, then connect the sink in the bathroom on the other side of the wall to this same horizontal line going into the "stack" that has back to back toilets going down, and a vent to roof going up.
My city uses IPC and I found that 3 sinks can go into on 1.5" drain, but I'm wondering about venting, sucking water out of P traps etc
Any tips would be greatly appreciated!
