I had a question for plumbing a 3 piece wet vent for a bathroom. This is a remodel of a 1950s bathroom and I was wondering if code allows a double wye to be used after the water closet bend?
The piping diagram is a bird eye view. The piping will be all horizontal just below the joists.
*Water closet bend is a 4” to 3”
*After double wye it ties into 4” main cast iron stack
