How CalDuplex works...
Water softeners work by a process known as ion exchange. The incoming water passes through a high quality resin vessel. The resin traps the calcium ions,
or limescale, from the solution and exchanges them for ions of sodium.
When the resin becomes exhausted, it is put through a cycle called regeneration by drawing a solution of salt and water (or more commonly known as brine). During regeneration, the calcium ions are then released from the resin and exchanged again with those of sodium from the brine. The unwanted ions are flushed to drain. Regeneration takes between 60 and 180 minutes, depending upon the size of softener and can be repeated as often as necessary.
