American Valve ScaleRX Water Heater Scale Prevention System

ScaleRX protects your water heater from limescale buildup and keeps it running efficiently. It requires no power supply, batteries, chemicals or filters. ScaleRX uses a patented turbulent galvanic polarization (TGP) electrode to disrupt the formation of limescale crystals on water heater elements. In side-by-side comparison testing, ScaleRX was four times more effective than the leading electronic scale device. ScaleRX is easy to install and maintenance free.
