High Flow Flap Valves are commonly installed at the end of your SCH40 Overflow Pipe for mosquito and pest protection. High Flow Flap Valves prevent birds from traveling up your overflow pipe and building a nest. They also keep squirrels and other rodents from and finding their way into your rainwater tank, where they usually can’t get out! Flap Valves allow a flow of air over the surface of the water which improves water quality and prevents a vacuum forming when large quantities of water are quickly drawn from the tank/cistern. A High Flow Flap Valve is recommended in every application where the overflow pipe is being plumbed on a rainwater tank.
