A water softener works by filtering out the minerals that cause hard water—mainly calcium and magnesium. Inside the system, water passes through a resin bed that swaps those hard minerals for sodium or potassium ions, which prevents scale buildup in pipes, fixtures, and water heaters. Over time, the softener regenerates by flushing the resin with saltwater to recharge it for continued use. For Littleton homeowners dealing with mineral-heavy water, a properly sized softener can make daily water use easier, reduce spotting and buildup, and extend the life of appliances.
