Softener installed, but water tastes metallic or has staining despite softening.

Safety: No hazardous work is required for basic checks.

• 1. Test water: Have raw and treated water tested for iron and manganese levels.
• 2. Clean resin: Perform an iron-cleaning regeneration with an approved resin cleaner.
• 3. Evaluate system design: If iron exceeds the softener's capacity, consult a RainSoft dealer about adding an iron filter ahead of the softener.
• 4. Adjust settings: Increase regeneration frequency or salt dosage within RainSoft guidelines to improve iron handling.
