Possible Causes
Cracked resin tank, Damaged tank base from impact, Pin‑hole leak due to manufacturing defect, Over‑pressurization of system
How to Fix / Troubleshooting
Safety first: Immediately place the softener in bypass and shut off the main water supply if the leak is severe. Do not attempt to repair a pressurized crack.
- Inspect tank: Dry the exterior and look for visible cracks or weeping at the base or sidewall.
- Check pressure: Verify that your system pressure is within the Nobel tank rating (typically under 6–8 bar). Install or service a pressure regulator if needed.
- Do not patch: Do not attempt to glue or patch a pressure vessel. This is unsafe.
- Replace tank: Arrange for replacement of the resin tank with a compatible Nobel‑specified tank. The resin and control valve can often be transferred by a professional.
