Abstract
A water softening system including a first treatment tank having a first water capacity, a second treatment tank in parallel with the first treatment tank and having a second water capacity that is less than the first water capacity, a flow meter connected to the first and second treatment tanks, the flow meter configured to determine a demand flow rate of water entering the system and a controller in communication with the flow meter, the controller configured to direct the water into the first treatment tank when the demand flow rate is greater than a designated flow rate, and to direct the water into the second treatment tank when the demand flow rate is equal to or less than the designated flow rate.
