Watts offers OneFlow anti-scale system

OneFlow from Watts prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These particles make their way through plumbing systems without latching on to pipes, fixtures, valves or heating elements.

The scale-control technology is designed to protect complete plumbing systems or individual components from the negative effects of water hardness. The environmentally friendly technology requires virtually no maintenance, no backwashing, no salt and no electricity. Models are available in cartridge and tank style housings for commercial applications on both cold and hot water lines. Systems are available in many connection sizes to meet flow rates from 0.5 to 450 gpm (1.9 to 1703 lpm) or more.
