I think my *GC* has screwed up. The wall where my sink is is only 3/4" in depth as it's up against my brick wall.
It was my understanding that the vent must ALWAYS be above the P trap.
Please see the pic attached. It is basically the underside of the kitchen from below - in the basement. The black pipe on the right is the DWV that is underneath the flooring and goes to the flooring where the sink cab is. However, the vent for the sink is tapped BELOW the P trap. The white APS pipe you see is the vent that the GC did .
Can anyone confirm is this is fine or WRONG ?
