I wish to install new waste line for washing machine and utility sink reusing existing cast iron drain which at some point was cut flush to concrete slab.
Background:
house built in 1929
4" cast iron waste line previously used for kitchen but "abandoned" and fitted with AAV during previous kitchen move/remodel
Old 2" CI waste from kitchen was "connected" to 4" using concrete patch/fill, see pic
Need:
Method for tying into cast iron waste line cut flush with slab (no hub) to accommodate washing machine and utility sink
So, I have searched for inside fitting to connect 1.5" or 2" waste line to existing 4" CI but only come up with water closet flanges. To vent, I will use AAV. How might one go about accomplishing this?
