Hard water is a common problem in homes across the country. In fact, studies have shown that approximately 85% of homes have hard water in their plumbing.
But what does this actually mean? What makes hard water a problem, and how does a water softener fix it?
Hard vs. Soft Water
Right from the start, the terms “hard” and “soft” water sound strange to people who aren’t specialists in water treatment. (How can water be “soft”? And isn’t “hard water” just ice?) But the concept isn’t that complicated. The hardness of water, which can be determined by professional water testing, is the amount of magnesium and calcium grains suspended in the water. The more grains, the harder the water. Water is considered hard when it exceeds 3 grains per gallon (GPG). Less than this is considered soft. Unfortunately, water hardness here in Maryland homes often exceeds 10 GPG, which is considered “very hard”!
