Honestly, no clue. That is all under the slab on grade which was built in the 1980s and well before I purchased the property. There is one other vent on the kitchen sink wall and it is possible they are vented there. The waste discharge is to the left of the photo (to street, gravity) and the kitchen sink is on the wall to the right. There is a vent and cleanout almost below that white pex you see extruding from the wall.How’s your tub and toilet vented ? Through that same 3” ?
If so it would’ve never passed inspection here originally.
