Hi Flow Mozzie Stoppa Flap Valves 90mm

Rain Harvesting's Mozzie Stoppa Flap Valves are mosquito and vermin proof because the 90mm and 100mm valves include a 0.955mm stainless steel screen that is moulded into a valve that can open and shut automatically to allow water to pass unobstructed. They fit directly to pipes leading to the tank and to tank overflow outlets.

The best kind of Flap Valves have a double seal, are self cleaning, and have flaps that cannot be over-rotated and left open. Vented 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.

It is recommended that they be fitted with silicone and not glued.
