PlumbEZ 1/2″ Part 1 Float Valve for Water Tanks and Cisterns
The PlumbEZ 1/2″ Part 1 float valve is a traditional ballcock for water tank, header tank and compatible toilet cistern applications. It is designed to help control the water level using a float arm and ball float, making it a practical replacement where a Part 1 ballcock valve is required.
This brass Part 1 float valve is supplied complete with a red ball float, so it is ready to fit as a replacement for suitable older-style installations.
As the water level rises, the float lifts the arm and closes the valve. When the water level drops, the float lowers and allows the tank or cistern to refill.
