I am adding a bathroom to my basement, which has partial (complete? ) plumbing already roughed into the floor (in 1976).
Sewage lift station (vented) is 3 ft from 4" styrofoam plug (toilet), 4 ft from 1 1/2 inch cast male pipe end extending through floor (lav, have already added vertical vent pie to the lav drain at this point), and 12 ft from cast iron floor drain. Unknown if all 3 fixtures originate from 1 line, or are 3 separate lines emptying into lift station. Floor drain and toilet are in direct line with lift station, lav is not.
I am installing an acrylic shower unit, the center of the shower drain falls exactly on the lip of the housing of the floor drain, and due to space limitations, the shower unit cannot be moved to line up exactly with the floor drain.
1. Is there some sort of fitting that would allow the shower waste water to be diverted horizontally into the existing floor drain? Is this even allowable per code? The floor level will be 1 inch above the rim of the cast drain housing (could cut a notch into housing?).
2. There is no evidence of any vent line anywhere on the floor drain line prior to the lift station. Do I have to rip up the floor anyway to install a vent line close to the shower?
3. Assuming the floor must be ripped up, what is the best way to cut cast iron pipe without requiring a large hole in the floor for access? A 2.5 ft, 4 in wide slot would allow access to the pipe without requiring removal of a lot of floor.
4. I am currently planning on using a rubber boot to connect the remaining cast pipe horizontally to a pvc T, from which a vent pipe would rise vertically and the shower trap would extend horizontally. Any better options available?
5. What sort of toilet flange fitting do I need for the stubout in the floor? How is this fitting connected to the pipe? Just slips in? If so, do I need to bolt the fitting to the concrete before installing the toilet?
Thanks for your insights.
