Details

The Polypipe PVS50 Air Admittance Valve provides a robust ventilation solution for larger 2″ domestic and commercial waste systems. Specifically, this 50mm solvent weld valve automatically draws air into the pipework during discharge to maintain the water trap seals. We manufacture the unit from durable ABS plastic to ensure the colour stays a clean white while providing a reliable chemical bond with standard solvent cement. This valve fits 50mm (2″) pipes and 55mm internal diameters. In short, it is the ideal choice for high-flow waste runs that require efficient, internal pressure balancing.

Larger 2″ waste pipes often carry high volumes of water that can easily create a siphon effect, pulling water out of every trap in the line. Furthermore, running a dedicated vent stack through the roof for a single high-flow appliance is both expensive and aesthetically unappealing. Specifically, a gurgling floor drain or a smelly shower area often indicates that the system is “gasping” for air. However, the Polypipe PVS50 Anti-Syphon Valve solves these heavy-duty ventilation problems within the room itself. It allows the system to breathe only when necessary, keeping sewer gases safely contained. Because the solvent weld join creates a permanent, air-tight seal, the valve remains a maintenance-free part of your plumbing. Therefore, you can ensure a silent, sanitary drainage system without the hassle of structural roof modifications.
