I have Sears Kenmore water softener that is a few years old (forgot # but it is a basic unit). My problem is that it will not consume all of the brine it generates. The level in the tank keeps increasing and I have to manually remove the excess brine. I have replace the venturi/gasket/screen system as a whole. It is possible that a leak into the tank exists through the rotating valve, but I have not checked this. The program on the computer is correct. The system works in manual and appears to have a good 'siphon' rate. The flow meter appears to be not working although I have not fully checked.
Any suggestions on where to look?? Should I disassemble the rotating valve and check the gaskets??
