The Topaz Part Fill Valve is a high flow valve for use in rainwater harvesting tanks.  The purpose of the float valve is to automatically maintain a low level of water in the tank during periods of no or low rainfall. This allows services fed by the tank to continue whilst leaving capacity in the tank for refilling by the next rain.

  • Rainwater harvesting tanks
