When to Replace the Anode Rod in A Water Heater? All water heaters have solid rods, usually in magnesium, aluminum, or zinc material suspended in the tank. This kind of sacrificial anode rod is to keep the steel tank away from corrosion. The working principle is simple. When two metals are in contact in a water solution, the more reactive metal will corrode completely before the less active metal begins to rust. Since magnesium, aluminum, and zinc anode are far more reactive compared to the steel in the water heater tank so that th

Why is the Hot Water Smelly Like Rotten Eggs? Some consumers have submitted comments about unpleasant odors similar to rotten eggs that seemed to come especially from the hot water. The rotten egg odor is caused by hydrogen sulfide (H2S) gas. The environment in water heater tanks provides an ideal environment for the production of hydrogen sulfide gas,since modern steel water heaters mainly are glass-lined to prevent corrosion. When a water heater tank is filled with water, an electrolytic reaction begins in areas that have e

Why MMO Tubular Anodes are Mostly Used for Groundbed Cathodic Protection? MMO tubular anode is an efficient choice for many underground cathodic protection applications. The mixed metal oxide (MMO) coated titanium tubular with a center connection was shown to be the most economical for this application. These types of electrodes were used in both surface and deep anode configurations. Since the anodic reactions are anticipated to be both oxygen evolution and chlorine evolution, it is important that the coating be a combination of i

MMO Ti Linear Anodes in Concentric Rings for Tank Bottom Cathodic Protection MMO Ti linear anodes in concentric rings have been used for tank bottom cathodic protection recently. This new design is easy positioning and high reliability comparing to MMO ribbon anode in grid configuration. This linear anodes in concentric rings system has no field cutting or welding—the anode rings are supplied factory assembled, tested, and ready to be laid into position prior to backfilling. The anode is typically backf
