Possible Causes
Broken lower distributor screen, Cracked riser tube, Excessive backwash flow rate, Overfilled resin tank
How to Fix / Troubleshooting
Safety first: Place the softener in bypass to prevent further resin migration. Depressurize the system.
- Clean fixtures: Remove aerators and shower heads to flush out resin beads. This restores flow and prevents clogging.
- Inspect tank internals: A technician should remove the control valve and inspect the riser tube and bottom distributor basket inside the resin tank. Replace any cracked or broken components.
- Check backwash settings: Ensure the backwash flow control is the correct size for the tank. Excessive backwash can fluidize and expel resin.
- Replace lost resin: After repairing the distributor, top up the resin bed with the correct volume of Nobel‑specified cation resin.
