Watts’ OneFlow^™ Anti-Scale System prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. The system uses environmentally friendly technology requiring virtually no maintenance, no backwashing, no salt and no electricity, to protect complete plumbing systems or individual components from the negative effects of water hardness. Models are available in cartridge and tank style housings on both cold and hot water lines. Many connection sizes are offered to meet flow rates from 0.5 to 450 gpm (1.9 to 1,703 L/m) or more. http://www.TheScaleSolution.com
