4"/110mm Buffalo Non Return Valve (Pack of Five)

4"/110mm Buffalo Non Return Valve Pack of 5

This pack of 5 Buffalo 4"/110mm Non Return Valves provides a reliable and cost-effective solution for protecting multiple drainage points from backflow and flooding. Designed to prevent wastewater from reversing through pipe systems, these valves help safeguard homes, businesses, and commercial propertiesparticularly in areas prone to heavy rainfall or located on flood plains.

When drainage systems become overloaded, effluent can be forced back into buildings, causing damage and disruption. Each valve in this pack allows water to flow in one direction only, effectively stopping backflow and reducing the risk of flooding across multiple installations.

In addition to backflow protection, these valves also offer strong pest control benefits. The flap is reinforced with an integrated stainless steel plate, preventing rodents from biting through. They also help stop frogs, snakes, and other vermin from entering drainage systems, making them ideal for both residential and commercial environments.

The valves also help prevent unpleasant odours by blocking noxious gases from travelling back into properties. This makes them especially suitable for hygiene-sensitive areas such as food preparation and catering environments.

Each unit features a lockable flap, allowing pipes to be sealed off during maintenance work. The valves are fully reusable, meaning they can be installed temporarily and used again when needed.

With a unique funnel-shaped body to improve water flow and reduce blockages, these valves are compatible with both clay and plastic pipes and can operate on a 45-degree bend. WRc tested and certified, each valve is built for long-term performance and backed by a 5-year manufacturers guarantee.
