Water softening is the process of removing minerals like calcium and magnesium, which cause hard water, from the water supply. It involves specialized equipment and skilled professionals who assess the source of water and determine the best water softening method. The most common methods involve using ion exchange resin or a salt-based solution to reduce the amount of minerals in the water. Proper water softening improves the water quality, increases the lifespan of appliances, and prevents plumbing issues caused by mineral buildup.
