How Soft Water Happens

Inside every AquaMaster® PRO water softener is a bed of specially engineered resin beads. These resin beads are charged with sodium or potassium ions known as regenerant. As hard water flows through the system, calcium and magnesium minerals — the minerals responsible for hard water — are removed through a process called ion exchange. The hardness minerals attach to the resin beads while soft ions are released into the water, providing your home with clean, softened water.

Over time, the resin beads become saturated with hardness minerals and must be recharged. AquaMaster® PRO systems automatically perform a process called regeneration, where a concentrated regenerant solution flows through the resin bed to remove the collected hardness minerals and restore the resin’s softening capacity.

During regeneration, the hardness minerals, dirt, and sediment are flushed safely to the drain. Once the resin beads are fully recharged, the system automatically returns to service, continuing to supply your home with soft, treated water for everyday use.
