A water softener reduces the hardness of water. This helps prevent scale build-up in pipes, fixtures, and appliances, and reduce staining, spotting and scaling. Other benefits of a water softener are cleaner & brighter laundry, smaller amounts of soaps and detergents are needed, and extended water heater life expectancy. Water Tender offers a variety of water softeners that meet your specific needs. Softening media is included in all units; brine salt must be purchased separately.
