I am looking to purchase a home and have run across a couple of plumbing issues. I don't believe the kitchen sink is vented properly or vented at all. Assuming the sink is vented, the distance from the p-trap to the where the vent ties in is 10 to 12 feet at least. Is this okay is there a chance that trap could be siphoned out?
An AAV would solve the issue pretty easily, but from what I have read they are a last resort. And I am not sure if they are even allowed. The home location is in Northport, NY.
I understand that the island should be plumbed like the image below and that makes sense. In order to not have the plumbing hanging to low in the basement and for the drain to be high enough to make it to the main stack without have move where it enters the stack how close (vertical distance) can the vent and drain be where the red arrows are?
