CalMag is a magnetic scale inhibitor containing a magnetic bar to induce a single polarity into the water causing the calcium and magnesium (limescale) particles to take on the same polarity. The particles then repel each other, and as a result prevent the formation of hard limescale.

CalMag can be fitted onto the hot or cold water lines. The unit is also available to fit 15mm and 22mm pipework. It comes with compression fittings as standard and does not require earth bonding. Once the unit has been installed you can sit back and relax as it will continue to work day and night without the need for regular maintenance.

After Installation you should instantly notice the benefits. Any hard limescale that has formed around taps, sinks etc, will begin to soften with regular contact with treated water. This will make it much easier to clean. Shower heads will gradually become descaled over time. Initially, showerheads may become blocked with loose limescale debris (often the case with electric showers). To solve this, simply remove the shower head and rinse out the debris. After several months your hot water system will gradually become more efficient. Eventually you should be able to lower the water temperature and make considerable savings over the year.
