Our Company

With the acquisition of Capital Plating and Machine Co. in 1982 (now known as Water Conditioning Controls) Capital Water Softener, Inc. and Water Conditioning Controls are two companies in one. A water softening company that can state they manufacture their own control valves are few and far between. With valves that are distributed throughout the United States, Canada and Europe, you know we’ve got to be good!
