Hard water is water that has a high mineral content, such as calcium and magnesium. While it’s not considered dangerous to safety or health, it can create costly maintenance problems in the home.
The most effective way to solve hard water problems is by installing a water softener. Most operate by filtering the water through large salt tablets replacing the harsh minerals with sodium. Small units can be installed in cabinets below the kitchen or bathroom sinks.
To solve the hard water problem throughout the house, a larger more expensive unit must be installed to filter the water BEFORE it enters the home. These units are about the size of a water heater and can cost a few thousand dollars, but in the long run, it can eventually pay for itself with the savings in maintenance problems created by continual exposure to hard water.
