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. The stack pipe leads the whole way out through your roof and further underground in the opposite direction to main sewer lines.

Through the stack sewer gases are carried up to the roof through vent lines. Vertical ventilation pipes called vent stacks provide air circulation to any part of the plumbing system. Vents provide a means to release sewer gases outside instead of inside the house. All open vent pipes that extend through a roof shall be terminated at least number typically 6 inches mm above the roof except that where a roof is to be used for any purpose other than weather protection the vent extensions shall be run at least 7 feet 2134 mm above the roof.

Drain pipes take the wastewater to the soil stack.

It helps maintain proper atmospheric pressure in a building s waste system and channels the exhaust gasses to the vent. Vents also admit oxygen to the waste system to allow aerobic sewage digestion and to discourage noxious anaerobic decomposition. The vent stack is the pipe leading to the main roof vent. Sub vents may be branched together to exit 1 vent stack allowing for only 1 hole in the roof for ventilation.
