Keep out pests and rodents

Keep mosquitoes, frogs and other pests out of the pipework and the tank of your system.

Let water flow

Whenever water is flowing, the Flap Valve automatically opens to let it out. This ensures unimpeded flow even during high rainfall events.

Simple operation

The foolproof design ensures that the flap remains closed when no water is flowing, and it can not over rotate or get stuck open. You’re always protected.

Vented Design

The vented design allows the system to breathe and also allows for smooth and quiet operation as both air and water enter the system during rainfall events.
