Fernco 160mm Single Flap Backwater Valve
A flooded property can be incredibly stressful, especially when the water is coming back through the drainage system rather than from outside. During periods of heavy rainfall, public sewers can become overloaded, increasing the risk of wastewater flowing back towards homes, commercial buildings and industrial premises. The Fernco 160mm Single Flap Backwater Valve has been designed to help reduce that risk, providing automatic protection without affecting the normal operation of your drainage system.
Installed within a 160mm drainage line, the valve allows wastewater to flow away from your property as normal. If backflow occurs, the stainless steel flap automatically closes, helping to stop contaminated water from travelling back through the drain and into your property.
Automatic Protection When You Need It Most
One of the biggest advantages of the Fernco 160mm Single Flap Backwater Valve is that it works completely automatically. There's nothing to switch on, monitor or operate.
During normal use, wastewater flows freely through the valve with minimal restriction. If the sewer network becomes overwhelmed and water begins flowing in the opposite direction, the stainless steel flap reacts immediately, creating a barrier that helps protect your property from backflow flooding.
It's a simple but highly effective solution that works quietly in the background, ready to respond whenever it's needed.
Built for Long-Term Reliability
Designed for larger drainage systems, the Fernco 160mm Single Flap Backwater Valve is built to provide dependable performance year after year. Its smooth internal profile promotes efficient water flow while helping to minimise the build-up of debris that could otherwise lead to blockages.
The durable stainless steel flap also helps discourage rodents from travelling through the drainage system, offering an added layer of protection. Once installed, the valve requires very little maintenance, making it a practical choice for contractors, developers, commercial premises and larger residential properties.
A Smart Investment for Flood Resilience
Whether you're installing a new drainage system or upgrading an existing one, fitting a 160mm backwater valve is a straightforward way to improve protection against sewer backflow. It can help reduce the risk of costly flood damage, minimise disruption and provide extra peace of mind during periods of heavy rainfall when drainage systems are under the greatest pressure.
