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.

Features and Benefits

  • Automatically opens & shuts
  • Prevents pests from entering the tank via the overflow
  • Higher overflow flow rate for high rainfall events
  • Self cleaning

Installation Instructions

Secure directly to the pipe outlet with or without silicone.

A small length of 100mm pipe will be required if connecting with 100mm Tank Overflow Outlet.
