I just wanted to post a thanks to Terry and all the contributors to this board. I just completed a total bathroom remodel that included opening up the basement slab, disconnecting a septic tank, creating all new plumbing under the slab (new walk in shower, toilet, lav) and teeing into sewer, including all the venting. I could not have done it without the information on this board. The new bath looks great and I saved 10's of thousands doing it myself.
