Possible Causes

Cracked brine tank, Loose brine line connection, Damaged brine float assembly, Overflow due to stuck refill valve

How to Fix / Troubleshooting

Safety first: Unplug the unit and place it in bypass. Mop up standing water to prevent slip hazards.

Steps to check:

  • 1. Inspect brine tank: Look for visible cracks or splits in the tank walls or bottom. If cracked, the tank must be replaced.
  • 2. Check brine line fittings: Tighten the nut where the brine line connects to the control valve and the brine well. Replace ferrules or O-rings if worn.
  • 3. Inspect float assembly: Remove the brine well cover and check the float and safety valve. Ensure it moves freely and shuts off water at the correct level. Replace if stuck or damaged.
  • 4. Verify refill control: If the tank overfills during regeneration, the refill valve or control valve may be allowing too much water. Inspect and clean the refill orifice and valve.

When to call a technician: For tank replacement or if the control valve is overfilling the brine tank, professional diagnosis is recommended.
