What are The Benefits of a Water Softener? A water softener reduces water hardness, making it easier to shower and clean fabrics and dishes. With softened water, less soap is needed for bathing and laundry. Skin feels cleaner and clothing softer. Pipes, fixtures and appliances have less scale build-up. With less build-up, appliances can operate efficiently. Mineral-derived odours may be reduced; and, there are fewer deposit stains on bathroom fixtures. for more info on the CMHC web site http://www.cmhc-schl.gc.ca/en/co/maho/wawa/wawa_005.cfm
