PlumbEZ 1/2″ Part 1 Toilet Ballcock Replacement
The PlumbEZ 1/2″ Part 1 brass ballcock valve is a practical toilet ballcock replacement for compatible cisterns, water tanks, header tanks and loft tanks. It is designed for traditional float arm installations where a Part 1 ballcock valve is required.
This product is supplied as the valve only. The ball float is not included, making it ideal if your existing float is still usable or if you are replacing only the valve body. If you need the complete setup with the red ball float included, use the related product option below.
A traditional ballcock valve controls the water level by connecting to a float arm and ball float. 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.
