The 48 1/2 inch tall OneFlow® anti-scale systems, condition cold and hot water and provides scale protection on internal and external plumbing surfaces to extend the life of equipment by transforming dissolved hardness minerals into harmless, inactive microscopic particles. They are installed upright at point of entry to a building for water below 110 degree F (43 degree C). The specially designed components work in applications before a water heater, boiler or other hot water device that requires protection from the effects of hard water. OneFlow® is not a water softener and does not add chemicals or remove minerals, but provides environmentally friendly technology to prevent scale buildup. The system consists of a black 10, 12 or 16 GPM tank with a 1 inch plastic MPT 90 degree elbow connection and media which should be replaced every 3 years.
