Sterling Water Treatment is a true manufacturer not merely an assembler. A wide range of components including both residential and commercial water treatment control valves are made in our Indiana facility. Our design team has focused on new products that are far more efficient, easier to service and provide more value to the consumer. Patents have recently been awarded to several of our team’s engineering and design improvements.
Free water analysis is offered at our factory lab. Only aesthetic contaminants are evaluated and the proper treatment options are recommended. Sample bottles are available from Sterling distributors nationwide.
As the leading supplier to the plumbing and well supply industries, Sterling products are sold by thousands of licensed contractors in North America. Sales and service support is generally found near to everyone.
Our roots go back to Charles Sidell and his one employee Emmitt Culligan. They began manufacturing manual water softeners in Fort Wayne way back in 1934. Most of the past 85 years the company has been under the same family ownership.
