I've got a clack WS-1 softener. It has been working just fine for the past 8 years. My problem is that it is wanting to regen every night. It is showing "regen today" in the lower-left corner of the LCD display.
I think the problem started when we were gone for a week and a toilet was left running. This caused the usage for a few days to go to about 5,000 gallons.
To try and fix it I performed a system reset. This reset the gallons used, gallons/day, etc. But that still didin't solve the problem.
Any ideas would be helpful.
