Many homeowners shrug their shoulders when it comes to the subject of hard water, but it’s such a common and easily remedied problem that a little knowledge on the subject is sure to make clear to you that soft water is a benefit to both you and many aspects of your home. 

 

We all learned in science class that water is the “Universal Solvent”, which is normally a good thing, but water can’t help but dissolve anything that it touches, and that includes the minerals that are most responsible for hard water, calcium and magnesium. Water is in its purest natural form inside clouds, but when it rains, the rain travels down mountains and over land to reach the reservoir, absorbing minerals all the way, and when those minerals appear in your water in significant enough amounts, you have a hard water problem.

 

 

A simple way to check whether your water is hard is to take a clean sealable container and place a little liquid soap or shampoo inside. Next, fill the container about half full and shake. In soft water, the soap will lather up very well, filling up the empty half of the bottle with suds. in hard water, through, the minerals don’t let the soap do its job, and instead it forms soap scum. Nasty, isn’t it?

What’s nastier is what hard water does as long as it’s running through your house. Some of the negatives of hard water include:

 

  • Scale collecting inside pipes and around fixtures
  • Decreased laundry detergent cleaning power
  • Possible skin irritation when soap is not completely washed off of skin after a bath/shower
  • Spotting and streaking on dishes and utensils
  • Damage to water-intensive appliances like water heaters and dishwashers due to mineral deposits
Fortunately, all of these problems can be avoided through the use of a home water softener. A typical home water softener operates on the principles of ion exchange. The hard water passes into the softener unit and through a bed of small resin beads no bigger than sand grains with usually are coated with potassium or sodium ions. When the water passes through the resin, the calcium/magnesium ions trade places with the sodium/potassium ions, softening the water in the process. Immediately, you’ll see the following improvements to your water:
  • You’ll have gleaming bathroom fixtures
  • You’ll need less detergent to clean the same amount of clothes
  • Your skin will be cleaner, and feel smoother and softer
  • You’ll eliminate streaking and spotting on your dishware
  • Greatly reduce scale collection in piping and water-intensive appliances
When you experience the benefits that soft water will bring to your home, you’ll wonder how you ever lived without it!
