#Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water , so we use the water softener . The resulting soft water is more compatible with soap and extends the lifetime of plumbing..

Water softening is usually achieved using lime softening or ion-exchange resins
water softening is necessary for boilers that produce steam to avoid lime deposition inside pipes or occurring corrosion to the pipes metal
Usually water #softener works by exchanging calcium, magnesium ions with sodium ions
Hard water fills the tank . As it passes through the #resin the hard water ions are attracted to the resin . by the time the water gets to the bottom of the tank it is soft .
