- What does it means when a softener regenerates?

Regeneration is the way a softener cleans its resin bed. Once the resin bed has exchanged all the sodium ions for calcium and magnesium ion, it must be cleansed so that it can continue to soften water A brine solution loosens the calcium and magnesium ions from the resin beads and flushes them to drain. The sodium ions from the brine solution replace the hard water ions on the resin beads so the system is ready to soften more water.
