Water Heater Anode
Water Heater 12/20 Gallon Magnesium Anode Rod. Tank-based water heaters are normally under a lot of pressure from the heat they produce and the acid that is contained in water. This makes them highly susceptible to corrosion.
Magnesium anode rods help to protect the inside of water heater tanks from corroding. They do this by diverting corrosion to themselves. Like their aluminum counterparts, they are also known as sacrificial rods. They are commonly used in areas that receive softer water and tend to last for a shorter period compared to Aluminum/Zinc/Tin anode rods. This is because they are more reactive and produce a higher voltage. Despite them wearing out faster than other sacrificial anodes, they provide several health benefits when dissolved in water.
