Welcome to the most complete Service Manuals Page in the water treatment industry! While every attempt has been made to cover all of the non franchise valves (Culligan, Kinetico, Rainsoft) systems there may be some missing. Please keep in mind that there are only a few valve manufactures in the world, but they make many different models for many different operators. If you do not find a service manual for a system that you have, please contact our office by e-mail, fax, or telephone, and we will be happy to assist you.
Water softeners are manufactured under many different names and sold to many Original Equipment Manufacturer (OEM) assemblers. These OEM assemblers then put there own special covers, colors, names, etc on them. Please look at the pictures we have provided next to each set of manuals, and if yours looks close, open that manual and compare components. Chances are you will find a system that is just like yours.
