The vent stack is the pipe leading to the main roof vent. The pipe leading to the main roof vent is called the vent stack. The plumbing vent pipe is a vertical pipe that attaches to the drain line and runs through the roof of a home. Vent pipes provide this air by running outside the structure of the house.

A full sized vent is a primary vent where the drain line transitions at some point and becomes the vent pipe that exits the roof. Re vent pipes otherwise known as auxiliary vents attach to the drain line near your fixture as they run upwards and over the main vent.
