The Floplast air admittance valve is designed to allow the free entry of air into the sanitary pipework system without the escape of foul gasses into the building. Avoids the need to penetrate outer roof shell.
It is recommended that air admittance valves are not used externally as environmental debris will affect the air tightness performance of the valve.
Key Features
