TL;DR
A plumbing vent stack is the vertical pipe that carries sewer gases up through the roof and admits air into the drainage system so traps keep their water seals when fixtures discharge. Without adequate venting, falling wastewater pulls a vacuum that siphons traps dry, producing gurgling drains and sewer odor indoors.
What it means
A plumbing vent stack is the vertical pipe that carries sewer gases up through the roof and admits air into the drainage system so traps keep their water seals when fixtures discharge. Without adequate venting, falling wastewater pulls a vacuum that siphons traps dry, producing gurgling drains and sewer odor indoors. The IRC sets minimum vent diameters and requires the termination to rise a set height above the roof, away from windows and air intakes.
