The Fernco 100mm Non-Return Valve provides a simple and reliable way to help prevent foul water and sewage backflow from entering your property. Designed for quick push-fit installation directly into an existing manhole pipe inlet, it requires no specialist tools or alterations to the drainage system.

Once in place, the valve allows wastewater to exit the property as normal but closes automatically if backflow pressure occurs, providing effective protection during sewer blockages or flooding events. This helps reduce the risk of water entering through toilets, waste pipes and drains inside the home.

The valve also offers protection against rodent intrusion. The stainless steel reinforced flap blocks rats and other pests from travelling back up the pipework, providing an additional layer of property security. Discreet when installed and easy to maintain, it provides a dependable flood defence solution for both residential and commercial buildings.

Suitable for 100mm pipes and compatible with all common pipe materials.
