Clearwater Enviros ScaleBlaster” eliminates mineral deposits that clog and corrode pipes, water heaters, dishwashers, faucets, drains and showerheads. A signal charge from the compact, integrated circuitry system changes limescale-forming molecule properties, causing them to repel rather than adhere to pipes and fixtures. Calcium deposits are dissolved and washed away. The easy-to-install unit features automatic 24/7 operation and requires no maintenance or chemicals. Expected lifespan is 20-25 years. A full five-year warranty is offered.www.clearwater-enviro.com info@clearwater-enviro.com
