CATHODIC PROTECTION - MAGNESIUM ANODES

The most common areas for unexpected leaks occur around unlined couplings, bushings, plugs and collars. The solution is to install sacrificial anodes, preventing corrosion cells from developing. Typically high potential magnesium anodes are installed and become part of a preventative maintenance program. Installing up to a thousand anodes yearly, HydraStone recommends future anode replacement based on longevity of other anodes in your area. In most cases anodes will only need to be changed every 2 – 5 years.
