Backwater Valves

Fernco In-Line Backwater Valves

Most of us never think about what's happening beneath our property until something goes wrong. But when drains become overloaded during heavy rainfall or the public sewer backs up, wastewater can flow in the wrong direction and cause serious damage inside your home or building. It's an unpleasant situation that can be expensive to put right.

Fernco In-Line Backwater Valves are designed to help prevent that from happening. Installed within your drainage system, they automatically allow wastewater to leave your property while helping to stop it flowing back in. It's a simple idea, but one that can save a great deal of disruption, clean-up costs and unnecessary stress.

At MP Products, we supply a range of Fernco In-Line Backwater Valves suitable for everything from domestic homes to commercial buildings and larger drainage installations.

Protection That Works Automatically

One of the biggest advantages of a Fernco Backwater Valve is that it works without you needing to do anything.

During normal use, wastewater passes through the valve just as it would through a standard section of pipe. If the public sewer becomes overloaded and wastewater starts flowing back towards your property, the valve automatically closes, helping to stop contaminated water from entering your drainage system.

Because it reacts automatically, you don't need to monitor it or manually activate it when bad weather is forecast. It's always ready to do its job.

Built for Everyday Reliability

Fernco Backwater Valves are designed to provide dependable protection year after year. They're suitable for new drainage installations as well as upgrades to existing systems, making them a practical solution for homeowners, builders, drainage contractors and developers alike.

Available in 110mm, 160mm and 200mm sizes, with both single and double-flap options, they're compatible with a wide range of drainage systems and can be connected using Fernco shear-banded or Icon couplings. Once installed, they require very little maintenance, giving you long-term protection with minimal effort.

A Simple Upgrade That Can Prevent Costly Damage

Sewer backflow can cause significant damage in a very short space of time. Installing an in-line backwater valve is a relatively simple improvement that can help protect homes, apartments, commercial premises, schools and industrial buildings from the disruption and expense of backflow flooding. It's a small investment that could save thousands of pounds in repairs and clean-up costs.
