Culligan Water Treatment Products in Ontario, CA
Water in Ontario, California is classified as hard to very hard. It reaches homes here from a blend of Colorado River water, the State Water Project, and local groundwater basins — all mineral-rich sources that leave calcium and magnesium behind as scale on fixtures, water heaters, and dishes. On top of hardness, the Environmental Working Group has flagged chromium-6, nitrates, and disinfection byproducts like HAA5 and TTHMs in the local supply. Culligan of Ontario carries equipment for all of it: water softeners and salt-free conditioners for scale, whole house filters for sediment and chlorine, reverse osmosis for drinking water, and bottle-free dispensers and ice machines for the home or office. Every system is sized to your water after a free in-home test and installed by a local Culligan Man.
