Floplast External Air Admittance Valve (Black)

The Floplast External Air Admittance Valve (Black) provides an effective way to maintain proper airflow within sanitary pipework systems while preventing the escape of foul odours. Designed for use in systems that meet BS EN 12056:2000 standards, this external valve helps prevent the loss of water from trap seals due to induced siphonage and offers the added benefit of acting as an early warning indicator of potential drainage blockages. By eliminating the need to penetrate the roof shell, it also ensures a more streamlined and aesthetically pleasing roofline.
