How Your Water Softener Works
Hard water contains calcium and magnesium. Your Kinetico water sys-
tem contains resin beads, which hold sodium ions. When hard water
passes through the resin beads (Fig. 3) inside a Kinetico water system,
the beads attract and hold the calcium and magnesium ions in ex-
change for sodium. After this ion exchange process, the water leaving your
Kinetico water system is soft.
Once the resin bed is loaded with calcium and magnesium ions, it must
be cleansed (or regenerated) so that it can continue to soften water. The
salt in your salt storage tank mixes with water to wash the resin beads.
The brine solution loosens the hardness minerals which have built up
on the resin beads; then the system backwashes and flushes the hardness
minerals and salt solution away.
