It helps maintain proper atmospheric pressure in a building s waste system and channels the exhaust gasses to the vent.
The venting system or plumbing vents consists of a number of pipes leading from waste pipes to the outdoors usually through the roof.
Because of this naturally occurring cycle the septic and sewer gases have a foul odor.
The plumbing vent pipe is a vertical pipe that attaches to the drain line and runs through the roof of a home.

Why plumbing air vents are important.
In most houses the main vent stack which opens onto your roof is a continuation of the soil stack which is the vertical waste pipe that leads to the sewer.
Vents also admit oxygen to the waste system to allow aerobic sewage digestion and to discourage noxious anaerobic decomposition.
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.
Vents provide a means to release sewer gases outside instead of inside the house.
