Sorry for the multiple posts...I work best keeping things separate.
the laundry room shares a wet wall with the bath, but is 3 feet higher than the floor of the bath.
I can finagle the laundry's 2 inch discharge line behind the tub surround on the drain side.
Can I simply connect this to the tubs drain line (after the tub's trap) with a Y connector, and importantly, can I then rely on the vent stack as the laundry vent.
As the crow flies, the 3 inch main vent will be about 6 feet away from the laundry down tub.
