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.When installed into sanitary pipework systems conforming to BS EN 12056:2000, the FloPlast Air Admittance Valve not only prevents the loss of water from trap seals due to induced siphonage, but also has the added advantage of providing an early warning indicator to a potential drainage blockage. Approved Document H of the Building Regulations only permits Air Admittance Valves that conform to BS EN 12380. Ventilation and access must be provided to all air admittance valve installations.
