I recently purchased this home and am interested in figuring out what these pipes are for, if not a rough-in.
I have a 3" pipe coming from slab at exactly 13" from wall on center.
Then three 1.5" (I believe. Can't measure easily) all between the studs behind it.
If this were for a rough-in, I'd assume another at the floor for shower, plus vent to the ceiling, but I see neither.
- This is a septic system
- I haven't tested to see where the 3" goes, however, I believe it may go to a sump in the center of the basement which is where I have softener drain being pumped up into the main. I have a separate foundation sump near the opposite end of the basement which is clearly just for gray water.
If it is for a bathroom, why three pipes on the wall? Why no vent?
