Details

The Polypipe PVS40 Air Admittance Valve offers a high-performance solution for ventilating 1 1/2″ domestic waste systems. Specifically, this 40mm solvent weld valve balances the pressure within your pipework by allowing air to enter when needed, which protects the water seals in your traps. We manufacture the unit from durable ABS plastic to ensure the colour remains a clean white while facilitating a high-strength bond with solvent cement. This valve suits 40mm (1 1/2″) and 43mm internal diameter pipes. In short, it is a vital component for ensuring a silent and sanitary drainage system in kitchens and bathrooms.

When multiple appliances share a waste run, the flow of water can create a vacuum that pulls water out of sink or bath traps, leaving your home vulnerable to sewer gases. Furthermore, installing traditional vent stacks through the roof involves significant labour costs and potential structural risks. Specifically, a gurgling bath or a smelly kitchen sink usually signals a ventilation failure that standard cleaning cannot fix. However, the Polypipe PVS40 Anti-Syphon Valve solves these pressure issues internally. It opens automatically to equalise air pressure, keeping your traps full and your home odour-free. Because the solvent weld join creates a permanent chemical bond, the valve stays securely in place for the life of the system. Therefore, you can resolve drainage noise and hygiene concerns with a straightforward, professional installation.
