How high should a air admittance valve be?


Can you vent plumbing through a wall?

Ideally, plumbing vents are installed on the roof for the gases to rise above and away from the dwelling. If that is not possible, it can go out a wall, but the exit must still be at least six inches above the roof line. This keeps the gas from seeping back in through windows or other openings in the building.

How do sink vents work?

A vent is a necessary part of the drain system for any plumbing fixture. Without venting, the negative pressure caused by the flow of draining water can potentially suck water out of the drain trap and allow sewer gases to enter the home. The vents allow air into the drain pipes to help keep the drain flowing properly.
