The 4 inch high flow flap valve, Bushman part number 39033, goes on the end of a 4 inch rainwater tank overflow pipe and keeps pests out of the pipework.
How it works
The plastic flap opens when water flows and closes when it stops, so mosquitoes, frogs and birds cannot get into the overflow line. Use it with the 4 inch Tank Overflow Kit, part 39025. The 3 inch version is part 39034.
