Non Return Valves

Our non return valve is part of the FlowPlumb Underground drainage system, is available in both 110mm and 160mm sizes, and fullfills two roles:

  1. Prevents flood water from travelling back up the drainage system into the home where it would cause financial and health damage
  2. Prevents rodents such as rats, and frogs etc from using the drainage system to enter the building

How it works

Non Return Valve

A flap inside the valve only opens one way. Water flowing away from the house pushes the flap open to allow free flow.

Flood water flowing back towards the house will push the flap shut, blocking the flow.

Non Return Valve

The same flap stops rats, mice and frogs etc from continuing further up the pipework towards the house.

The valve can be opened for maintenance so needs to be accessible. The flap can also be locked shut if a flood is known to happen.
