Septic Tank Air Vent

What is a Septic Tank Air Vent? Why do I need it? The septic system including its plumbing pipes, is sealed. Anaerobic digestion of sewage releases septic gases like methane and hydrogen sulfide which become trapped in the sealed septic tank causing a buildup of gases. The air vent is crucial for the proper functioning of the septic tank because it helps to prevent any buildup of septic gases like methane.

A buildup of Methane which is a highly flammable gas, can cause the septic system to explode. Septic gas buildup also results in odors and can restrict the flow of waste causing sewage backup in your house.
