The short answer
The float shuts off the brine refill if the valve sticks open, stopping an overflow; replace it if it sticks or leaks.
How it works
It rides up with the water level and closes a valve in the brine line if the level rises too far.
Signs of trouble
- Brine tank overflowing.
- Float stuck or cracked.
- Brine line leaking at the float valve.
