Scalewatcher 3 Star hard water solution. An earth friendly and Efficient treatment for Hard Water!

Compact in its design, the Scalewatcher 3 Star is an eco-friendly and cost effective electronic descaler for your home. Designed for indoor residential use only, the Scalewatcher is an excellent way to address hard water problems in your home. While not harmful to you, hard water can wreck havoc in your home; creating scale build-up in your pipes, on your faucets and on heating elements in washing machines. Because it uses very little energy, the Scalewatcher 3 Star can cost as little as $14 per year! The Scalewatcher 3 is environmentally friendly because it does not use any salt or chemicals like other water softening systems, making it gentler for your skin. Whether you have municipal water or well water, the 3 Star is the right choice for treating hard water in your home.

The Scalewatcher 3 Star unit consists of an electronic unit and a coil, which is wrapped around the pipe of the incoming water supply. The Scalewatcher 3 Star is easy to install and maintenance free. It is compatible with all types of pipes, including copper, steel, PVC and lead; all you need is at least 4” of straight pipe in order to properly install the unit. The patented technology of the Scalewatcher generates an electric field that agitates scale-forming calcium and magnesium ions in the water causing them to remain in suspension. This results in the water hardening elements to flow with the water down the drain instead of adhering to pipes.

Not only will one Scalewatcher 3 Star descale and protect your whole home, but it will prevent new scale from forming on everything from sinks and bathtubs to hot water systems and appliances, extending their life and improving their efficiency. Unsightly existing scale found on faucets and showerheads is softened over time with the use of a Scalewatcher making it easier to remove. Note: this action will temporarily increase the hardness of the water until all the scale layers have been removed.


The Scalewatcher 3 Star is guaranteed to prevent or considerably reduce the accumulation of scale and to remove already existing scale during the first 30-90 days of installation. If you are not completely satisfied with the results of the Scalewatcher 3, email our company, A.M.I. Services, within 12 months from delivery to obtain a Return Merchandise Authorization (RMA). Once the unit has been returned and determined to be undamaged, a full refund of the purchase price will be issued.

In order to be eligible for the money back guarantee, you must have continuously operated the Scalewatcher unit for at least 6 months.

If you believe the 3 Star unit is not operating correctly, please contact our company, A.M.I. Services, before disconnecting the system.
