Non Return/Backwater Valves

Non Return & Backwater Valves

Our Non return and backwater valves are a simple but highly effective way to protect properties from one of the most unpleasant and costly drainage issues, backflow. When drainage systems become overloaded, particularly during heavy rainfall, water can be forced back through pipes and into buildings. This can lead to flooding, contamination, and significant damage to floors, walls, and equipment. Installing the right valve helps prevent this by ensuring wastewater can only travel in one direction.

These valves are commonly used in both residential and commercial settings, especially in areas where properties are located below street level or connected to shared drainage systems. By automatically closing when reverse flow occurs, they act as a reliable barrier against sewage and stormwater re-entering the property. This added protection helps maintain hygiene standards and reduces the risk of disruption caused by unexpected flooding.

Protection Against Backflow and Sewer Flooding

During periods of intense rainfall or drainage system overload, water levels in public sewers can rise quickly. Without protection, this pressure can force contaminated water back into connected pipework. Non return and backwater valves are designed to respond instantly, closing to block reverse flow and helping to keep interiors dry and protected.

Durable, Practical and Low Maintenance

Designed for long-term use in demanding environments, these valves are made from robust materials that can withstand constant exposure to wastewater. They operate automatically and require very little maintenance beyond occasional inspection. This makes them a practical, cost-effective solution for property owners looking to safeguard their drainage systems and avoid costly repairs in the future.
