Hello, I have Culligan Mark 812 which continuously regenerates it is half full of salt which appears not to go down, the drain hose I guess it it's called, continuously drains water. I have unplugged the unit from the power source and by passed the water softener just to get it to stop regenerating. not sure what to do or look for. I live intown so have city water. Please help. Can't afford to replace at this time. Thank You in advance.
