Hi and thanks again. Can I drain my 1.5" (could be 2" if needed) into the back of my 3" toilet drain? I don't see why not but maybe it's not best practice. Between some conduit and the joists I don't believe I have enough headroom to run the 3" pipe all the way back to the vertical sink pipe and get enough slope.
Mainly I want to add a cleanout somewhere since my 100-year-old CI doesn't have one. Can it be on the back of the 1.5" pipe (drawing # 1) or does it need to be part of the 3" size (drawing #2)? I think I read in the UPC code that it says it needs to be the same diameter as the main pipe so 3"? If so should I use a Tee of a Wye?
If this is a bad idea I was originally going to plumb it like in drawing number 3, but the sink drain now happens to be very much so in line with the toilet. Which way would you do?
Thanks a bunch.
