Water from the Aquabion softener has a salty taste after regeneration.

Safety first: Do not drink water that tastes strongly of salt; use an alternate source until resolved.

• Check regeneration settings: Verify that the rinse cycle duration in the Aquabion controller meets or exceeds the manufacturer's recommendation.
• Inspect drain line: Ensure the drain hose is not restricted or kinked, allowing full rinse flow.
• Examine brine valve: A leaking brine valve can allow brine into service water. Inspect and replace the brine valve kit if it does not close completely.
• Run an extra rinse: Manually initiate a regeneration and allow an extended rinse to flush residual salt from the resin bed.

Warning: Persistent salty taste may indicate a serious valve fault; consider professional inspection.
