Waste Vent Roof

Many fixtures are not so conveniently located however and other solutions must be found.

Waste vent roof. A true vent is a vertical pipe attached to a drain line that travels through the roof with no water running through it. If a fixture is close to the stack and on the top floor the upper part of the stack serves nicely as a vent. Vents also admit oxygen to the waste system to allow aerobic sewage digestion and to discourage noxious anaerobic decomposition.

Vents provide a means to release sewer gases outside instead of inside the house. The venting system or plumbing vents consists of a number of pipes leading from waste pipes to the outdoors usually through the roof. The stack pipe leads the whole way out through your roof and further underground in the opposite direction to main sewer lines. The vent pipes are part of the drain waste vent or dwv system of a house or building and they do not carry water inside them.

The stack also allows fresh air in to keep water running smoothly through your piping. Drain pipes take the wastewater to the soil stack. Water and waste head down the pipe while gasses are vented up and outwards. Instead they serve to equalize air pressure within the dwv system and also release sewer gases into the outdoor air as all vent pipes terminate through the roof.
