HiI have fitted an on suite bathroom in a loft conversion but had to use a saniflo plus. Waste goes straight down useing a 32mm pipe reducing to a 22mm pipe. All works fine and no hassle.
My dillema is i now need to fit a shower room on the floor below, directly underneath the on suite, again I will have to fork out for another saniflo but i am trying to understand if I can connect into the waste I have already run to the main drain ie the 32mm pipe? or if I do will the waste from upstairs come rushing in the showertray
Any way to have a none return valve or something thanks jansco
