What is a Water Softener and How Does it Work? A water softener is a device that removes hardness from water, typically by exchanging calcium and magnesium ions for sodium ions. This process, known as ion exchange , occurs within a resin bed, which is composed of small, porous beads made of a material called ion-exchange resin. Why is a Water Softener Needed for Well Water? Well water often contains high levels of dissolved minerals, including calcium and magnesium, which cause hardness. Hard water can create several problems, such as: Scale Buildup : Hard water can cause scale buildup in pipes, appliances, and fixtures, reducing their efficiency and lifespan. Soap Scum : Hard water can make it difficult to create a lather with soap, resulting in soap scum buildup on surfaces.
