Flap Valves (Frog Flaps)

Self-cleaning and self-closing for minimal maintenance and greater peace of mind, our flap valves (aka frog flaps) keep mosquitoes, frogs and other vermin out of your downspout and tank overflow pipes. The flap opens to let water pass through and immediately self-closes to keep your pests out of your pipework.
