Brine tank fills with water and may overflow after one or more regenerations.

Safety first: Bypass the softener and unplug power before servicing. Mop up any spilled brine to prevent slipping.

• Check drain line: Ensure the drain line from the Fleck valve is not kinked, frozen, or blocked. Clear any obstructions and verify that the drain line terminates with an air gap.
• Inspect brine valve and float: Open the brine well in the brine tank and verify the safety float moves freely and shuts off water at the correct level. Clean or replace if stuck.
• Verify refill time: In the control programming, confirm the brine refill time is appropriate for the brine tank size and salt setting. Reduce if excessively high.
• Service brine valve in head: Remove and inspect the brine valve assembly in the Fleck valve. Replace worn O-rings or the entire assembly if it leaks or fails to close.
