It is a vertical pipe attached to a drain line and runs through the roof of your home. Plumbing vent pipes are connected to your drain system and are needed for water to drain properly. Vent pipes run from waste or drain pipes upwards ending outside the building usually sticking up through the roof. Venting is critical to the operation of a residential or commercial plumbing system.

The typical vent system consists of a network of pipes that connect to every drain p trap and extend via a main stack that pokes through the roof just above the main bathroom. When water drains air must replace the space that was taken up by the water. This is best implemented if a fixture rests close to the stack and the top floor of your home allowing the stack to serve as a vent. This allows unpleasant and potentially dangerous odors or fumes to safely leave your plumbing system escaping harmlessly into the air outside.
