Safety: Do not consume water that tastes excessively salty until the issue is resolved.

Steps:

Check programming: Verify that the backwash and rinse times are set according to Clack specifications for your resin volume. Increase the final rinse time if necessary.
Inspect drain flow control: Ensure the correct DLFC (drain line flow control) is installed for your tank size. An undersized DLFC can reduce rinse effectiveness.
Examine piston and seals: Remove and inspect the piston and seal pack for wear or misalignment that could allow brine to bypass into service. Replace the piston and seal kit if worn.
Check brine concentration: Extremely high salt settings or very small brine tank volumes can cause overly strong brine. Adjust salt dose to manufacturer recommendations.
Flush system: After corrections, run several regeneration cycles and flush household lines before using water for drinking.

Tip: A slight temporary saltiness immediately after regeneration can be normal; persistent strong salt taste indicates a fault.

Clack water softener causes a salty taste in the softened water after regeneration.
