The person who sets up the softener takes an educated guess at the capacity of the softener (how many gallons of water it can treat between regenerations) then another guess at how many days it will take for the inhabitants of the home to use that number of gallons.

For example, if it seems that the softener can treat 1000 gallons of water between regenerations and that the family will use about 300 gallons of water per day, the softener might be set to regenerate every third day. That allows a little room for error.
