What symptoms should you document?
A symptom alone is not a diagnosis. Your system's model, age, and service history help narrow causes when tracking these common changes:
- Water feels hard again or spots return on dishes
- Salt use changes noticeably
- Regeneration runs at odd times
- The unit leaks, displays an error, or makes unusual noise
When does repair deserve consideration?
Repair may be reasonable when the problem is isolated, parts can be confirmed for the exact model, and the unit fits household demand. Persistent hardness, iron interference or repeated failures may call for an assessment of replacement or pretreatment.
What should you have ready for a repair visit?
Having accurate system details ready helps an installer assess equipment without guesswork:
- Locate the brand, model, and serial number on the unit
- Note the approximate installation date and current salt type
- List recent symptoms, water source, and test results
- Clear physical access around the unit and plumbing shutoffs
