Softener occasionally allows hard water through before regeneration occurs

Safety: Monitor water hardness while adjusting capacity settings.

• Re-test hardness: Confirm raw water hardness and update the controller setting if it has changed.
• Increase reserve: Adjust reserve capacity or safety factor so the unit regenerates before resin is fully exhausted.
• Stagger heavy use: Avoid running multiple high-demand appliances simultaneously if possible.
• Resin cleaning: Perform a resin cleaner treatment if fouling is suspected.
