- 1. Thaw slowly: Use warm air (space heater or hair dryer on low) to gently warm the area around the softener and pipes.

- 3. Repair leaks: Replace any cracked components before returning the unit to service.
- 4. Prevent recurrence: Insulate pipes, add heat tape where appropriate, or relocate the softener to a conditioned space.
