Fernco 200mm Single Flap Backwater Valve
When heavy rain puts extra pressure on the drainage network, the last thing you want is wastewater flowing back towards your property. Unfortunately, when public sewers become overloaded, that's exactly what can happen. The Fernco 200mm Single Flap Backwater Valve has been designed to help prevent this by automatically stopping backflow before it has the chance to cause damage.
Designed for 200mm drainage systems, this valve works quietly in the background every day. Under normal conditions, wastewater passes through the valve without restriction, allowing your drainage system to operate exactly as it should. If water begins to flow back from the sewer, the stainless steel flap automatically closes, helping to stop contaminated water from entering your drainage system.
It's a simple piece of equipment, but one that can make a significant difference when drainage systems come under pressure.
Protection That Works Automatically
One of the best things about the Fernco 200mm Single Flap Backwater Valve is that it doesn't rely on anyone being there to operate it.
There's nothing to switch on, no settings to adjust and no emergency procedures to follow. The valve simply responds to changing flow conditions automatically, giving you added protection whenever heavy rainfall or sewer surcharging occurs.
That means whether you're on site, at work or away from the property, the valve is always ready to do its job.
Designed for Long-Term Performance
Drainage products need to be dependable, and that's exactly what Fernco has designed this valve to be.
Its smooth internal body allows wastewater to flow efficiently during everyday use while helping to reduce the build-up of debris that could lead to blockages. The durable stainless steel flap is built to withstand demanding conditions and also acts as a barrier against rodents, helping to reduce the chance of unwanted pests entering through the drainage network.
Once installed, the valve requires very little maintenance, making it a practical choice for commercial developments, industrial premises, apartment blocks and larger residential drainage systems.
A Small Addition That Can Prevent Major Problems
Backflow flooding can cause extensive disruption, expensive repairs and lengthy clean-up work. Installing a backwater valve is a relatively simple upgrade that can help reduce those risks, giving you greater confidence that your drainage system is protected when heavy rainfall places extra demand on the public sewer network.
