Water hardness is a measure of the concentration of dissolved minerals, primarily calcium and magnesium, in water. Hard water can cause a variety of problems, including scale buildup in pipes and appliances, soap scum, and dry skin. Checking water hardness is important for determining the best water treatment methods for your home or business.
There are a few different ways to check water hardness. One simple method is to use a water hardness test kit. These kits are available at most hardware stores and home improvement centers. To use a test kit, simply collect a sample of water and add the test solution. The solution will change color depending on the hardness of the water. Another method for checking water hardness is to send a sample of water to a water testing laboratory. This is a more accurate method, but it can also be more expensive.
