Water is highly solvent and corrosive which is potentially damaging to the surface metals within a water heater, boiler or storage tank and these components are expensive and often complicated to replace.
Water heater anode rod is typically made of either aluminum, magnesium or Zinc. They are referred to as“sacrificial anode rod".Hot water heater sacrificial anodes are installed in order to protect the water tank against corrosion. The anode sacrifices its metal content to protect the hot water heater against corrosion and leakage. This extends the lifetime of water heaters and water tanks.
