RainSoft Over-Regeneration

Softener regenerates too frequently, wasting salt and water (no code)

Possible Causes

Hardness set too high, Flow meter over-registering, Small capacity setting, Plumbing cross-connection causing meter to spin

How to Fix / Troubleshooting

Safety: No hazardous work required for basic checks.

  • 1. Verify hardness: Test raw water hardness and adjust the programmed hardness accordingly.
  • 2. Check capacity and reserve: Ensure the programmed capacity matches the resin volume and that reserve is not set excessively high.
  • 3. Inspect for cross-connections: Ensure there is no plumbing loop that allows water to flow backward through the meter (e.g., incorrect bypass piping).
  • 4. Test meter accuracy: Compare meter reading to a known volume of water. Replace the flow meter if it over-registers significantly.
