How to Fix / Troubleshooting
Safety first: Do not apply open flame to thaw frozen components. Shut off water and power before inspection.
- Thaw slowly: Use gentle heat (space heater, warm air) to gradually thaw the area around the softener. Do not pressurize the system until fully thawed.
- Inspect for cracks: Once thawed, check the control valve, brine tank, and piping for cracks or leaks. Replace any damaged parts.
- Insulate and protect: Add insulation around pipes and the softener, and ensure the installation area is kept above freezing. Consider relocating the unit if necessary.
- Test operation: After repairs, run a manual regeneration and monitor for leaks and proper cycling.
