Possible Causes

Insufficient rinse time, High salt dosage, Internal valve leakage between brine and service ports, Incorrect cycle programming

How to Fix / Troubleshooting

Safety first: Do not drink water that tastes strongly of salt until the issue is resolved.

Flush system:

  • Run cold water at several faucets for 5–10 minutes to flush residual brine from the plumbing.

Check settings:

  • Verify the salt dosage and regeneration cycle times in the controller. Excessive salt dose or shortened rinse can leave brine in the resin bed.

Valve integrity:

  • If salty taste persists long after regeneration, internal valve seals or pistons may be leaking brine into service water.

Resolution: Adjust programming to manufacturer-recommended settings. If the problem continues, have a technician inspect and rebuild the control head with new seals.
