Water has a salty taste after regeneration.

Safety first: Unplug the unit before changing programming or inspecting the drain line.

Check drain line:

• Ensure the drain line is not kinked, elevated too high, or partially blocked.
• Verify that the drain line air gap or standpipe is not restricting flow.

Programming adjustments:

• Increase the rapid rinse time slightly within AO Smith’s recommended range.
• Verify that the salt dosage is not set excessively high for your hardness and capacity.

After adjustments, run a manual regeneration and flush several gallons of water from a softener-fed faucet before drinking.
