Introduction to Non-Return Valves (NRV)

Fernco’s range of retrofit Non-Return Valves (NRV’s) can be installed directly into existing manholes by simply pushing the NRV into the desired pipe inlet.

An effective prevention for backflow, the product stops foul water from blocked sewerage systems, averting potential flooding inside properties through toilets, plug holes, and waste pipes.

The Retrofit NRV’s effortless pushfit design means it can be fitted in minutes and does not require any specialist expertise or equipment.

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