General Information
The FloPlast Air Admittance Valves are 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. The AF110 Push-Fit Air Admittance Valve may also be used as a secondary rodding point to remove such blockages.
All Valves should be stored in an upright position.
Approved Document H of the Building Regulations only permits Air Admittance Valves that conform to BS EN 12380.
