The Fleck operation is mainly based on ion exchange. This means minerals like calcium and magnesium which makes limescale in your appliances and damage them and also make water hard are treated by sodium ions which are harmless. It removes minerals like calcium and magnesium and makes the water soft.

Such type of water softener eventually reaches their capacity and so they regenerate themselves by removing unwanted ions. When a water softener is regenerating then the water produced at that time is not soft and so it becomes unusable at that time. Meter based regeneration system is used by the water softener and there are a total of 4 modes of operation:

  1. Immediate meter regeneration
  2. Delayed meter regeneration
  3. Delayed time clock regeneration
  4. Day of week regeneration

It is to note that most of the settings are time-based. If the system is very expensive, then there will be more sophisticated electronics and automatic regeneration is there in optimum time.
