Use less soap, and remove scale from your pipes - continuously, automatically and for only about $5 in electricity a year. Clearwave is the most advanced computerized anti-scale device available today. Its computer chip is programmed to bombard water passing through your pipe with over 200 different electromagnetic low frequency pulses. These electromagnetic pulses have been scientifically proven to increase the electromotive attraction potential of the water to mineral salts. The result is that the mineral salts (mainly calcium bicarbonate) stays dissolved in the water instead of converting to insoluble calcium carbonate and attaching itself to the inside of pipes as scale. Existing scale in pipes, water heaters, toilets and faucets begin to soften and dissolve away, as well. Recommended for dishwashers, washing machines, coffee makers, and boilers. # Clearwave Electronic Water Conditioner Clearwave can even replace base exchange softening systems and the associated maintenance costs. Installation of the Clearwave is simple. Mount to the main incoming water pipe to the home with pipe clips, wrap the antenna leads around pipe and then plug into a 110V power supply. One unit handles incoming supply pipes up to 1" in diameter. For pipes 1 1/4" to 1 1/2" use two units in series. Works with all types of pipe including: copper, pvc, galvanized, and stainless steel.
