4"/110mm Buffalo Non Return Valve

The 4"/110mm Buffalo Non Return Valve is a reliable and practical solution designed to protect properties from the risks of backflow and flooding. When drainage systems become overloaded, particularly during heavy rainfall or in flood-prone areas, wastewater can be forced back through pipes and into buildings. This valve helps prevent that by allowing water to flow in one direction only, stopping effluent from re-entering homes, businesses, and commercial premises.

Widely used in properties located on flood plains, this valve provides peace of mind by acting as a barrier against sewage backflow. It also offers an added level of protection against pests. The flap features an integrated stainless steel plate, preventing rodents from chewing through and gaining access. In addition to rodents, it helps stop frogs, snakes, and other vermin from entering drainage systems and properties.

Another key benefit is its ability to reduce the risk of unpleasant and potentially harmful odours. By blocking backflow, the valve also prevents noxious fumes from travelling back into buildings, making it particularly suitable for environments where hygiene is critical, such as the food and catering sector.

The valve includes a lockable flap, allowing users to temporarily seal off pipe access when carrying out essential maintenance. It is fully reusable, meaning it can be installed during maintenance work and removed for future use as needed.

Its unique funnel-shaped body is designed to improve water flow through the unit, helping to reduce the likelihood of blockages. The valve is compatible with both clay and plastic pipe systems and can even operate effectively on a 45-degree bend thanks to its innovative flap design.

Tested and certified by WRc, the Buffalo Non Return Valve is built to deliver dependable performance and comes complete with a 5-year manufacturers guarantee for added reassurance.
