Aqualine Air Admittance Valve

Aqualine Air Admittance Valve (AV3240) – Venting Without External Pipes

An air admittance valve (AAV) is a one-way mechanical valve that allows air to enter a waste plumbing system to prevent negative pressure and siphoning, without requiring an external vent pipe through the roof.

In caravan self-containment systems, an AAV allows your grey water waste system to function correctly and drain freely, without the need to run a vent pipe outside the vehicle.
