How does a water softener work?

A water softener works by using a process called ion exchange to remove calcium and magnesium ions, which are the primary minerals responsible for water hardness, from your home’s water supply. The system typically consists of a mineral tank filled with resin beads that attract and hold onto these hard water minerals. As hard water flows through the tank, the resin beads exchange sodium ions for hardness ions, effectively softening the water. Periodically, the system regenerates, flushing the trapped minerals out of the resin bed and recharging it with sodium ions.
