How Magnesium Anode Rod Works
The anode rod is one of the most important factors in determining the life of your water heater. An anode rod is a steel core wire surrounded by one of three common sacrificial metals. These metals include aluminum, magnesium, and zinc. Anode rods are commonly used in water heaters or similar application areas. The rod is designed to corrode instead of the object you want to protect, in this case, your water heater. The anode rod of magnesium will corrode, and you will have to replace it year after year. It’s also very common as the magnesium anode start to corrode, it will start to give away a small scent of rotten eggs (hydrogen sulfide gas).
How Corrosion Guard Powered Anode Works
As soon as the current rectifier is connected to the nearest outlet, the Corrosion Guard anode supplies a small amount of current into the storage tank. This small amount of current completely prevents the corrosion of your water heater or tank. Since the anode is made out of titanium, it does not disintegrate over time, hence you would not need to change it every year!
