Ground water is usually higher in mineral content than surface water in the very same area. This is due to the longer exposure to rock formations and since water is a universal solvent, it dissolves anything it comes in contact with. Water hardness is nothing more than dissolved limestone. Some of the signs of hard water are dry itchy skin, dry scalp, soap curd in the shower or tub, poor results with cleaning products, low or no suds, scaling in pipes, problems with any water using appliances or maybe a residue left behind on fixtures.
The installation of a Water Softener will solve all of these problems and more. The plumbing and fixtures represent approx. 15% of your home's value. In protecting this part of your investment, a water softener more than pays for itself.
