Is this type of configuration acceptable in New Jersey? In lieu of a loop vent? Basically dropping the trap 1.5 inch into an oversized (3 inch)vented drain line?
Any feedback appreciated.

They have plumbing now in New Jersey???
Probably not acceptable....
I'm not a professional plumber, but I would suspect the concern would be if there is a toilet attached to that three inch line and if "wet vents" are allowed.

You need a tee and a studor vent after the trap before it drops to the 3"
studor vents not allowed in my area...
I decided to do the loop vent into a vented drain. I hope the inspector is ok with it.Tim
Up size to 2" and it should be fine. Thats what my township inspector "suggested" cause 's not allowed to tell me how!
Its never caused any problem in the last 5 years.
