Possible Causes
High iron content exceeding softener design, Resin fouled with iron, No iron removal pre-treatment, Infrequent regeneration
How to Fix / Troubleshooting
Safety: If water is visibly discoloured, avoid drinking until quality is confirmed.
- Test for iron: Use an iron test kit on raw and treated water to determine iron levels.
- Resin cleaning: Perform an iron-removal resin cleaner treatment following Ecowater or chemical supplier instructions.
- Increase regeneration frequency: Adjust hardness or capacity settings so the unit regenerates more often, reducing iron loading.
- Consider pre-treatment: For high iron levels, install an Ecowater iron filter or other dedicated iron removal system upstream of the softener.
