Hi. New DIYer here. I wanted to know if there is a maximum distance for a fixture (kitchen sink) to the roof vent stack penetration? The diagram might explain it better. You can see the kitchen sink is on 1st floor and is about 26' horizontally from the 3" vertical soil stack that will run out the roof. BTW, this will be all new plumbing for an addition/remodel I am doing to my house. The only existing plumbing is the 3" septic line running to the septic tank.
Also, any other comments on the layout? Last, I live in New Jersey so not sure if you need to know that.
Thanks a LOT!
