Air Admittance Valve Installation

Last updated: March 9, 2026

The key difference between a functioning drainage system and one plagued by siphoning and foul odours is often the Air Admittance Valve (AAV). The AAV is a vital, one way air inlet that automatically opens when negative pressure occurs in the soil stack or waste pipe. This action equalises the pressure, preventing the loss of water seals in appliance traps and protecting the property from foul air and gurgling noises.

This course on Air Admittance Valve Installation will give you the essential technical and regulatory knowledge to select, site, and install Polypipe Building Products AAV’s correctly, as seen in our Above Ground Installation Guide.
