Do You Have Hard Water In Your Home?
What is hard water?
Water from underground sources collects dissolved minerals from rock--particularly calcium, magnesium carbonate, and manganese.
Generally, water that contains more than 3.5 grains per gallon (GPG) of dissolved hardness minerals is considered somewhat hard and water with more than 10.5 GPG is very hard.
When hard water is heated, dissolved minerals re-crystallize and form scale that eventually clogs plumbingand can reduce water flow.
Scale and lime deposits build up in water heaters and other water-heating appliances such as dishwashers and coffee makers, increasing the need for repairs.
Hard water problems are more obvious in cleaning and bathing. Calcium and magnesium react with many soaps and detergents, diminishing their lathering or cleaning capability and forming a scum that is difficult to rinse away. Problems include spotted dishes and scale on cookware, bathtub ring and tile scum, and gray, stiff clothing. When bathing, you generally need more soap or shampoo and must rinse more thoroughly.
If you suspect hard water, you can call your municipal water authority or a private water testing firm. You may need to install a water softener in your home.
