Possible Causes

Loose brine hose connections, Cracked brine elbow on Cillit valve, Damaged brine well grommet, Aged tubing

How to Fix / Troubleshooting

Safety: Isolate the softener and avoid slipping on spilled brine.

  • Tighten fittings: Check all brine hose nuts and push‑fit connectors at the valve and brine well. Tighten hand‑tight plus a small additional turn.
  • Inspect tubing: Look for cracks, discoloration, or stiffness in the brine tubing. Replace with new Cillit‑approved brine tubing if degraded.
  • Check grommets: Inspect the rubber grommet where the brine tube enters the brine well. Replace if hardened or cracked.
  • Test under operation: Run a regeneration and watch for leaks during brine draw and refill.
