am trying to remodel a bath on an upper level, about 3' above lower level in older house. Problem is I see no signs of venting, or traps. the drains are in poured concrete slab. there is no signs of stacks on roof or through the walls. lower part has 2 baths both which seem to be correct, both with vent stacks.
I have all walls exposed from the inside and there are no vents going up. The drains all seem to go straight down about 36" before they elbow. so now i am trying to figure out what in the world they did here. I don't know how operational this was as to drain flow as it was not in working order when I bought the house.
so I guess my question is, is am I going to have to jackhammer down to add traps and ventlines or is there some kind of setup I don't know about?
I really don't smell sewer gases but I don't see a normal setup. any ideas? thanks
