A water softener uses charged resin beads to attract and remove hard minerals from water. These minerals stick to the resin, while softened water moves into your plumbing system for daily use.
Over time, the resin becomes full of minerals and needs to be cleaned. During the regeneration cycle, the system uses salt or potassium chloride to flush away the collected minerals and recharge the resin. This allows the unit to continue providing soft water for your Minnesota home.
