To prevent the formation of limescale, mineral-rich tap water must be softened. Water softening involves the use of an ion exchange resin device, where the resin is negatively charged and is bonded to positively charged sodium. As water flows through the device, an ion exchange occurs and leaves behind mainly sodium ions that do not form harmful deposits unlike limescale.
Salt, however, poses a different problem as the sodium content of softened water is not naturally occurring. Consequently, excessive intake of high-sodium tap water can damage internal organs and cause irreversible medical conditions. To remedy this, you may want to enlist the services of a trusted Saskatoon plumber from a company like Perfection Plumbing & Drain Cleaning Ltd. Such a plumbing professional may suggest installing a reverse osmosis system.
