Forum Title: Under slab DWV Does this look right?
Looked odd to me but I figured the guy knew what he was doing, Starting to have doubts about that. This is a very large master bath. There is no direct vent for the toilet or the tub. The only pipes that go up are the 3" standalone vent (on shower wall) and 2" for vanities (connects to the 3" in attic) First pic sketch of pipes under slab, not to scale. Second pic, overview...pipes left to right: shower, 3" vent, lavatory, tub, toilet Third pic, closer view, left to right: shower, 3" vent, tub

Concrete is already poured, house is half finished at this point. Inspector passed it. Other bathrooms are similar. Getting very worried

to be blunt. **** plumbing no vents, incorrect backfill, pipes not bedded, i see voids under pie that means bellys and stoppage latter someone is plumbing that does not know what they are doing if inspection passed...you have a inspector that is overworked and is just signing permits, not doing his job

Your suspicions are correct. The tub, shower and toilet need their own vents. If the job is being inspected then the inspector should catch the problems before concrete is poured and also that the proper backfill is used such as gravel, sand, etc.
