While a non return valve is suitable for virtually all domestic situations – it’s worth noting that non return valves don’t always meet the rigorous standards required from a ‘check valve’ – so even though the terms are used interchangeably – it’s important to check that it definitely is a non return valve you need for your job. this non return valve is designed to be use with 160mm underground drainage pipe.

Fitting a drain non return valve in your property or home’s drainage system inspection chamber outside

Our single flap backwater non return valves are compatible with virtually any underground drainage system – and are quickly and simply pushed to fit into both plastic and clay pipe sizes in the inspection chamber. These non return valves are 300mm long – so you just need to make sure you’ve got the correct amount of space in the stack so the valve can sit where it’s needed to prevent back flow from storm water.

How does a single flap drainage non return valve work?

The most important component in this type of valve is a stainless steel flap – designed to open under the water pressure of a flow out of the building – but snapping into a closed position if back flow water pressure comes from the other side.

If water rises through the pipework and hits the valve, the stainless flap returns to the closed position, preventing ingress and potentially saving the property from significant damage.
