The Fleck 5600 Metered Water Softener regenerates based on the amount of water used, saving both salt and water. 

The Fleck 5600 SXT hard water softener uses an Electronic Keypad Display to set the values instead of Mechanical Dials. With the SXT Meter version, you can set the maximum number of days between regenerations in case the preset amount of water used is not met in this time period. This ensures that the softening resin does not sit idle in the tank too long in cases where not much water is being used.
