A note from Sid Baysinger, President of Tankless Pros Az, LLC

I recommend this product for all types of Arizona water heaters.


What is it? And What does it do?


ScaleRx is a limescale inhibitor device that is used to prevent 76% on average of limescale buildup that will occur inside most Arizona water heaters. Adding a ScaleRx limescale inhibitor will help to extend the life expectancy of your new water heater and extend the service required from once a year to only once every 2-3 years. Having us install a ScaleRx unit on your new water heater at the time of installation is a smart choice.


After just 1-year from new installation

ScaleRX protects your water heater from limescale build-up and keeps it running efficiently. It requires no power supply, batteries, chemicals, or filters. ScaleRX uses a patented Turbulent Galvanic Polarization (TGP) system to disrupt the formation of limescale crystals on water heater elements. ScaleRX was four times more effective in side-by-side comparison testing than the leading electronic scale device. ScaleRX is easy to install and maintenance-free. Now available in 3/4 inch & 1 inch sizes.

Over 90% of Arizona homes have hard water, which causes limescale build-up, reducing the lifespan and efficiency of water heaters and home appliances.

Limescale build-up can block pipes and faucet aerators and cause corrosion. It’s also unsightly, leaves deposit on clothes and dishes and is a constant nuisance for homeowners. More significantly, limescale build-up on water heater elements reduces their overall efficiency and drives up energy bills.

ScaleRx uses a patented Turbulent Galvanic Polarization (TGP) system to disrupt the formation of limescale crystals. Independent testing shows that ScaleRx reduces scale accumulation by 76%. In side-by-side comparison testing, it was four times more effective than the leading electronic scale reduction device.
