Product Description

FloPlast External Air Admittance Valve 110/82mm AX110 Black

General Information

This FloPlast External Air Admittance Valves Push Fit 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.

Document H Clause 1.31 states that "Ventilating pipes open to outside air should finish at least 900mm above any opening into the building within 3 metres". This new development by Floplast of an External  Air Admittance Valve, will allow the installation of an external soil pipe within 3 metres of any opening and terminate at the same height as if it were installed internally, ie 200mm (minimum) above the highest wet entry point to the soil vent pipe. See diagram below.
