Rain Harvesting by Blue Mountain Co. Flap Valve Vent Screen
Hi-Flow Flap Valves allow a rapid flow of water through a double sealed, self-cleaning valve 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.
