Is Anode Rod Necessary?

Yes, an anode rod is necessary. It protects your water heater from corrosion and extends its life. However, once the magnesium or aluminum from your anode is dissolved, the steel walls of your water heater will start to rust.

    The rods are NOT made of aluminum, as aluminum is not corroded by water.

      Steve, aluminum will corrode in water and that’s why they are used to make certain sacrificial anode rod.
