Installed directly into a residence's main plumbing network, a standard water softener operates via ion exchange—a fundamental method where hard minerals are substituted with alternative elements, typically sodium. Water hardness levels are quantified using grains per gallon (GPG) or milligrams per liter (mg/l), which correspond directly to parts per million (ppm). Specifically, water measuring up to 1 GPG (equivalent to 17.1 mg/l) is classified as soft, whereas water falling within the 60 to 120 GPG range is categorized as moderately hard.
