Description

Non-return valves allow sewer or surface water materials to freely flow in the direction of the systems mains but block backflow of those materials in the opposite direction in instances, such as, flooding.

Non-Return Valves (NRV’s) can be installed directly into existing manholes by simply pushing the NRV into the desired pipe inlet. The product prevents foul water flowing back from the blocked sewerage systems to flood the property from the inside via toilets, plug holes and waste pipes.

Users also benefit from protection against rodent infestation. The stainless steel reinforced flap helps to block rats and other
rodents and insects from traveling up pipes and into homes and commercial buildings.

Non Return Valve to fit DN150 pipe inlets.
Nominal Dia. (mm) - 150 mm
