Searching for a way to vent a desired basement utility sink, I had hoped to wye into the vent line of the first floor bathroom sink.
Now I question if my first floor bathroom sink is vented properly. It simply has a p-trap into a 4-inch waste stack that handles a second floor
toilet and basin. It works because the 4-inch stack probably never gets filled enoughto create a vacuum
and pull from the basin trap, but I question it. Is this, or was this ever, according to code?
