How far can a vent stack pipe be from the last fixture

Hi Kevvkevv

It depends on the fixture, it also depends on if it is a single fixture vent, a whole bathroom group vent, or a wet vent venting multiple fixtures. If this is actually a VENT STACK only and it has no fixtures connected to it then distance isn't really a factor in most cases.

Anyway, need more details here. What fixture or fixtures are you talking about and believe it or not we also need to know what state you are in as most states have different vent distance requirements?

Back to you...
