Sunnyvale has wonderful drinking water. In this age of bottled water that costs more than gasoline, it's good to know that we have clean and tasty water coming from our taps. However, as I learned after my second instant hot water gadget corroded, there is a price to pay. This tap water is also extremely hard, and corrosion can build up in pipes and our hot water heaters. Water softeners are one solution, but must bypass the cold water pipes, because of excess salt in the process, not suitable for drinking.
Mr. Handyman sent me an email, describing a device that de-scales piping systems and hot water heaters and prevents future scaling from occurring. It clamps around the cold water pipe entering the water heater, is then plugged in, and works by emitting a somewhat random electro-magnetic field thereby causing the minerals in your water (which are apparently magnetic) to constantly jerk around in your plumbing system, which in turn causes them not to adhere to the side of the pipes and water heater. The device will even de-scale the mineral deposits that have adhered to the sides of your pipes and water heater.
He tested it, and it works. His wife has a very sensitive sense of smell and is very bothered by spotted glasses coming out of the dishwasher. She now claims the glasses are never spotted, she no longer buys the anti-spot rinse agent, and the funny smell the dishwasher has given off for years is gone.
