Description
The 110mm Underground Drainage Non Return Valve is designed to prevent backflow within 110mm underground drainage systems. The 110mm Underground Drainage Non Return Valve allows wastewater to flow in one direction while stopping reverse flow from entering the drainage run.
110mm Underground Drainage Non Return Valve Installation & Use
The 110mm Underground Drainage Non Return Valve is manufactured from durable PVC-U for long-term underground performance. It is resistant to corrosion, ground chemicals, and typical soil and moisture conditions found in UK drainage installations. This makes it suitable for domestic, commercial, and groundwork applications.
The valve features an internal flap mechanism that automatically opens with forward flow and closes when reverse flow occurs. This helps protect properties and drainage systems from flooding, foul water backup, and unwanted return flow during heavy rainfall or system surcharges.
The push-fit socket connections include integrated rubber ring seals for secure and watertight installation with standard 110mm underground drainage pipes. This allows quick fitting while accommodating minor ground movement after installation.
This fitting is commonly used in low-level drainage systems, extensions, basements, and areas prone to backflow risk. The smooth internal bore supports consistent flow while maintaining reliable system performance.
Compatibility: The 110mm Underground Drainage Non Return Valve is compatible with all standard 110mm underground drainage pipes, bends, couplers, junctions, and access fittings used in UK underground drainage systems.
