According to the manufacturer, the Aqua-Rex (shown above) emits radio waves thru antenna wires that loop around an incoming water supply pipe (shown below), and the radio waves modify the iron (Fe) molecules in the water in such a way that they attract the scale-forming particles of hard water to attach (nucleate) to the iron instead of encrusting the interior surfaces of a home’s plumbing system. The very fine particles are then carried away in the water flow.
That’s the theory anyway. It sounds more than a little suspicious, but the system was tested by a professional lab to a protocol for scale removal adopted by the International Association of Plumbing and Mechanical Officials (IAPMO), and found to reduce scale accumulation by 83%. A recent issue of PM Engineer magazine featured those test results and, although it seems too good to be true, apparently it is. The customer reviews of the device on amazon.com were split between “it’s wonderful” and “useless, don’t buy it.”
