In my 100+ year old home there is an obvious cast-iron sewer stack extending through the house--exposed in the basement. There is also a 3" ABS pipe coming out of the slab floor in another area of the basement. This ABS pipe has no vent (even though the kitchen sink currently drains into it).
I am looking to add a bathroom on the main floor, and it would be much easier to properly vent and hook the bathroom into this pipe than extending a 3" drain line across the basement. However, I have been told that this pipe may hook into the storm system and not the regular waste system.
Is there a way to identify where this pipe goes? It is possible that it is routed into the sewer system under the slab, but I don't want to drain a toilet into it unless I know for sure.
