ScaleBlasters compact, integrated circuitry system sends a scientifically developed signal charge to an induction coil that is simply wrapped around the water supply pipe entering your home before your water heater. These inaudible sonic pulses change the electrical and physical properties of the lime scale forming molecules causing them to repel, rather than adhere to water pipes and fixtures such as sinks, faucets, dishwashers, showerheads, commodes, etc. The calcium deposits are dissolved in the water and never return again.
