This 68 inch tall OneFlow (R) anti-scale system conditions 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. It is installed upright at point of entry to a building for water below 110 degrees F (43 degrees 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 (R) 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 75 GPM tank and can be installed in a manifold assembly with multi tanks parallel for high flow applications, a 2 IN FPT top mount inlet and outlet connections and media which should be replaced every 3 years.
