Basement drainage

I moved into a brand new home late 2017. The unfinished basement has drainage rough ins. 3” 13 inch from the framing for a WC. 1 1/2 for the sink and a 2” up against the stud and about 15” centre from the alcove. The permitted drawings show future bath, WC and sink.

my question is will the 2” rough in for the bath have a trap under the slab. If I have to install a trap it will be major work.

apreciate all feedback.

rgds, ct

If there's a cap on it, take it off and look to see if there's standing water. If not, pour some in and see if it stays there.

Yes, took the cap off and standing water. But the cap is also on at the other end where the 3” goes to the sump so I need to take that off and see if the water in the 2” drains out.

If the drawings show WC and sink, the 2" pipe is likely a vent. Also, if it's against the wall (which I think you said), it's probably a vent.

If it was for a shower, it would most likely be 16-18" out from the wall.
