The Brine Refill Cycle

The first stage of the regeneration process is the brine refill cycle during which water flows into the brine tank creating a salt brine solution. With most modern water softeners, this begins 60-90 minutes before backwashing begins. With older models, the brine cycle may be the last step in the regeneration process. If your brine tank always contains water, you have a so-called “wet” brine tank system.

Backwashing

Next comes a short, preliminary rinse cycle. Water is directed upwards through the resin tank and out the drain, flushing out any accumulated iron or dirt particles to improve resin efficiency.

Brine Draw

Step three is the brine draw cycle during which saltwater solution flows from the brine tank into the resin tank through the brine valve. This brine rinse triggers the ion exchange process, replacing the hard water minerals in the resin bed with sodium ions.

Fast Rinse Cycle

The fast rinse cycle sends mineral compounds and any remaining brine solution down the drain, restoring the resin bed.

Slow Rinse Cycle

Finally, a short slow rinse restores the normal direction of water flow and settles the resin beads back into their usual position. The service cycle is now complete, and voila, you can now enjoy soft water.
