I'm adding a flush in my basement where there was a utility sink. My issue is that the cast iron pipe exited the house comes through the cement floor vertically in the area of the toilet and the previous sink drain entered the drain pipe too high for the toilet drain. I want to stay away from a mechanical up flush. Right now I have about 10" of 4" cast iron up to a 4" to 3" cast iron reducer, then a 4" cast iron "T" (?) then up to 3" PVC.
My intent was to remove the cast iron reducer and "T" and replace with a 3" PVC sanitary "T" and adapt the 3"PVC to the 4" cast iron drain as low as possible with a Fernco (?) 4" to 3" reducer? A short floor build-up is acceptable in this space. Lastly, can I use a Saniflo 003 rear outlet bowl without the macerating unit? It would seem to discharge to the drain pipe just like the macerator?
