Brine tank overflows or fills with too much water after regeneration.

Safety: Immediately stop water flow to the brine tank by placing the unit in bypass and, if necessary, disconnecting the brine line. Clean up any spilled brine to prevent corrosion.

Steps:

• Inspect brine valve: Remove the Clack brine valve assembly from the valve body. Check for debris or scale preventing full closure. Clean or replace the assembly if it does not move freely and seal properly.
• Check safety float: Open the brine well and inspect the safety float. Ensure it moves up and down freely and that the check valve at the bottom is not stuck open. Replace the safety float assembly if it leaks or sticks.
• Examine brine line: Look for kinks or obstructions that could cause pressure buildup and backflow into the tank. Replace damaged tubing.
• Verify programming: Confirm that the brine refill time and flow are set correctly for your system. Excessive refill time can overfill the tank.
• Test operation: After repairs, run a manual regeneration and observe the brine fill and shutoff to ensure the water stops at the correct level.

Note: Salt mushing at the bottom of the tank can also interfere with float operation; clean the tank if necessary.
