Lochinvar & A.O. Smith 100283579 Magnesium Anode Rod
Replace your worn sacrificial anode rod and extend the service life of your water heater with the Lochinvar & A.O. Smith 100283579 Magnesium Anode Rod. Engineered as a genuine OEM replacement component, this anode rod is designed to protect the inner lining of your water heater tank from corrosive electrochemical reactions — keeping your system performing reliably for years to come.
How It Works
Sacrificial magnesium anode rods work by attracting corrosive elements in the water supply, oxidizing in place of the tank’s steel lining. Regular replacement of the anode rod is one of the most cost-effective ways to maintain water heater efficiency and prevent premature tank failure.
