Latest water treatment technology. This OUTBACK unit was developed for our customers in Australia and the Western US States per their request for an extremely powerful, non-electrical unit. Hundreds of thousands have been sold with bad water in Australia, Great Britain, Israel, Middle East, Western US States, and we get compliments every day. A very heavy 3 and a half pound set of bars with 10 extra-large N45 grade neodymium magnet set of two unit bars which simply straps to your main water inlet to your without tools and without plumbing modifications. Anybody can install it. This is about 50 times more powerful than our Standard units. Solid galvanized American steel base with several coatings to handle indoors or outdoors. No brand gives you more power. Not all neodymium magnets are the same potency though they may be the same size. And since they create a magnetic field within the inlet pipe which performs the conditioning function, this difference is critical. Water contains minerals, including lime, calcium, magnesium, and the worst the water, the more minerals translating to hard water. This system uses basic physics to change the molecular structure of the ions in minerals, as the minerals remain suspended in the water while it flows, causing them not to stick to dishes, skin, fixtures, pipes, and pipe walls. Those minerals still suspended, completely go through your plumbing system and out the drain instead of being deposited into your fixtures, pipes, dishes, skin, etc. USA made. There are other units with ceramic magnets, which basically are toys. The rating of the magnet force is critical, and none are close to this unit for the price. Thoughtful instructions included and everything you need is included, including Velcro and nylon straps and foam cushions. Fits any size pipe up to 4", and any material. Never needs maintenance. Not an ounce of plastic. Over 11" length. Made in USA.
