Abstract
The present invention provides a method and system of anticipating salt depletion in a brine tank of a water softener system, the system including a controller having a user interface and display, the method comprising the steps of tracking salt usage; determining the amount of salt remaining in the brine tank; calculating the number of days before salt is required in the brine tank based on salt usage and the amount of salt remaining in the brine tank; and providing an indication of the number of days to empty, whereby a user is able to anticipate the need to replenish the salt supply and plan accordingly to assure continuous satisfactory operation of the water softener system.
