Hello all,
I have torn out the CI waste pipes and replaced with PVC. I basically copied the layout from the cast iron, but it occurred to me codes may have changed or I may have used the wrong fittings, so I figured it would be a good idea to get some feedback before calling it done. The layout is odd because the waste pipe going to the septic is on one side of the room and the vent stack is on the other side of the room. So under the toilet we have:
a 3” combo wye going across to the vent stack
under that is a 3” / 2” double san-T for the 2 branches
at the bottom is the closet bend out to the septic tank
I will attach a couple of pics, I hope it all makes sense.
I am particularly concerned about the double San-T I used under the toilet. I read something that made me think I should have used a double fixture T instead, and also, is it okay for it to be directly under the toilet?
Thanks
Martha
