Details
Admittance Valves (AAVs) serve as a reliable solution for introducing air into the plumbing drainage system without requiring a conventional vent pipe. Their primary function is to prevent the release of sewer gases into the building environment.
Each AAV operates as a one-way valve, opening automatically to admit air when negative pressure occurs within the piping system. When pressure equalizes or becomes positive, the valve closes by gravity, effectively sealing the vent terminal to maintain system integrity. This closure occurs under both zero differential pressure (no-flow conditions) and positive internal pressure scenarios.
Every unit is rigorously engineered and tested to ensure consistent performance and long-term reliability.
