The vent stack is the pipe leading to the main roof vent. Running a vent pipe out of the roof takes some careful preparation.

Increasing the vent opening to three inches just before it goes through the roof in frost prone areas is another precaution that prevents blockages.

Through traps all fixtures are connected to waste lines which in turn take the waste to a soil stack or soil vent pipe. The main stack is the heart of the venting system. A stack vent is the extension of the waste stack to provide venting. If you can t put the main stack through the roof most local plumbing codes allow you to put it through a wall instead but there are conditions.

Plumbing vent pipes are connected to your drain system and are needed for water to drain properly. At the building drain system s lowest point the drain waste vent is attached and rises usually inside a wall to and out of the roof. When water drains air must replace the space that was taken up by the water. Vent pipes provide this air by running outside the structure of the house.
