Questions and answers
The water level in the salt tank is about 4 inches above the salt level when the tank contains about 3 inches of salt. What’s wrong with my water softener?
The issue with the Autotrol 255-460i water softener could be related to the brine control or the air check valve. The brine control regulates the amount of salt used during regeneration, and if it is not functioning correctly, excess water may accumulate in the salt tank. Additionally, if the air check valve is not working properly, it may not stop water from flowing back into the tank after the brine draw cycle, leading to a higher water level. Checking and adjusting the brine control settings and ensuring the air check valve is functioning properly may resolve the issue.

@Mr. Anderson Many thanks for responding to my question. My next question is how do I adjust the brine control settings and how do I ensure that the air check valve is functioning properly?
