FLOPLAST EXTERNAL AIR ADMITTANCE VALVE (BLACK)
Details
- The Floplast Air Admittance Valves are designed to allow the free entry of air into the sanitary pipework system without the es cape of foul gasses into the building.
- When installed into sanitary pipework systems that conform 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.
- All valves should be stored in an upright position.
- Saves the need to penetrate the out roof shell, giving more aesthetic rooflines.
