Hi, Jason here and a remodeling/tile contractor by trade.. Am doing a bath remodel which looks like the drawing I am attaching, but have a couple plumbing questions. It seems someone has updated this house by retrofitting 3"PVC drain stack to replace the original Cast (there is still a 2 foot section.)
This drain line runs down the basement walls probably 30 feet before going out. What I am wanting to do here is seperate this bathroom into two with a wall right behind the tub. I will be adding another toilet, and a shower to this setup. Can the 3" stack support all of this ok? Just wondering because I usually see 4" in most houses. Also there may be another vent in the wall where the double sink is but I am not positive. If not can I use one way valve vents under the sinks in both baths to offset the lack of venting?
Thanks
