This is Oregon, so a version of UPC.
I want to drain my double vanity sinks in the wall horizontally into the 2” toilet vent. I think this is called wet venting the toilet. The two sinks will combine to 2” pipe and drain into 2” toilet vent. I will use appropriate LT fittings for all vertical to horiz transitions. Just want to make sure this is legal.
Sink will dry vent into toilet vent mid way up wall.
