The Bonaire cistern ball float valve (6050916SP) is our best-selling Bonaire evaporative cooler float valve. It works like a toilet cistern valve: as the water level in the cooler tank rises, the float lifts and shuts off the water supply, keeping the tank at the right level.
Cooler leaking or overflowing? Our evaporative cooler leaking water guide helps you find the cause from the symptom.

About Bonaire & Celair evaporative cooler float valves
Signs of a worn float valve include water overflowing from the cooler, a tank that won't fill, a constant trickle from the overflow, and scale build-up that stops the float moving freely. The valve suits many Bonaire, Celair and Climate Tech evaporative coolers; check the fitment on the product page against your model.
On coolers with a water inlet solenoid, the two parts work together: the Bonaire solenoid valve switches the supply on and the float valve controls the level. Also see Bonaire cooler pumps and the dial flow valve. Contact us with your model number for help.
