McAlpine VP100N Solvent Weld Air Admittance Valve Grey

The McAlpine VP100N Solvent Weld Air Admittance Valve (AAV) is a crucial component for modern above-ground drainage systems. It is designed to replace traditional open vent pipes, providing a sealed solution that allows air to enter the system when needed, preventing the suction of water from trap seals and the associated unpleasant odours. Its primary application is where soil and waste pipes terminate inside a building, making it an ideal choice for internal bathroom and kitchen installations, extensions, and loft conversions where routing a pipe to an external wall is impractical or costly.

Crafted from high-quality materials, this valve features a robust grey polypropylene body designed for long-term reliability. The EasyFit mount type simplifies installation, allowing for a secure and straightforward connection. The valve operates silently, opening automatically when negative pressure is detected within the drainage system to admit air and equalise pressure, then sealing tightly to prevent the escape of foul air back into the living space.
