plumbing vent
Drain air passage
A plumbing vent is a pipe that allows air into a drainage system, preventing the vacuum that would otherwise slow drains or siphon water from traps.
Vents typically extend through the roof, releasing sewer gases safely above the building.
Without proper venting, drains gurgle and traps lose their water seals: The slow kitchen drain turned out to be a blocked plumbing vent.
