: : I am remodeling a bathroom and want to change the position of the fixtures. Presently I do not see that the lav,wc, or tub are vertically vented. I do not understand wet venting. The bathroom is about 4 1/2 feet wide, 7' long. The soil pipe is at the end, under the joist, horizontal. As you walk in I want the fixtures on the left--lav, wc, left hand tub. Can you tell me how to rough the drain and vent for UPC.

This is a REAL PROFESSIONAL plumbing job.

Notice no Billy Butt Crack AAV installed.
