Scale Build Up What Is It
All water supplies well or municipal have scale or what we refer to as hard water. The levels may vary levels below 7gpg aren't really an issue levels 0f 7gpg and above should be treated with a water softeneing system. Scale in the water is dissolved stone rain water passes thru the soil dissolving softer rock such as limestone making the water neutral and imparting scale into the water. We have shipped softeners to areas of kansas with 105 gpg of hardness in the water. Scale in the water will build up in your plumbing and water using appliances causing damage and inefficiency. the only true way to remove scale is with an ion exchange water softener it is the only household water filter that will remove scale.
