Why plumbing air vents are important. It is a vertical pipe attached to a drain line and runs through the roof of your home. In all cases the ducting needs to conduct the exchaust to the building exterior and needs to terminate in an animal proof vent cover. It channels the exhaust gases to the vent and helps maintain proper atmospheric pressure in the waste system.

Running a vent pipe out of the roof takes some careful preparation. Venting through a roof vent or exhausting them in the attic could cause moisture problems and rot. The best exhaust fan venting is through smooth rigid ducts with taped joints and screwed to a special vent hood. Vent your bath and kitchen exhaust fans through the roof through a special roof hood.

Vent pipes provide this air by running outside the structure of the house. When water drains air must replace the space that was taken up by the water.
