I recently bought a bi-level home and the first floor is unfinished. However, the plumbing is ruffed in for a full bathroom.
I;m not sure how to vent the fixtures, or if I need to vent the fixtures.
There is a 2" PVC pipe running to the bathroom on the 2nd floor which vents out of the roof. I don't believe the vent is connected to the ruff plumbing on the first floor.
Is there a simple way to vent the ruff plumbing on the first floor? And how do I determine what (toilet, sink, tub) needs to be vented?
I believe the ruff plumbing is drained under the slab in the garage.
The vent pipe that exits the roof appears to come up through the slab and drains the washing machine... it then continues up to the 2nd floor bath and exits the roof.
My main concern is moving forward with completing the 1st floor bath and it not being vented... is there anyway to test if its vented or not?
