Description
Lochinvar & A.O. Smith Magnesium Anode Rod — SKU 100288573
This OEM replacement magnesium anode rod from Lochinvar & A.O. Smith is engineered to protect water heater tank linings from the inside out. By attracting corrosive elements in the water supply through a natural electrochemical process, the sacrificial anode rod corrodes in place of the tank wall — dramatically extending the service life of the water heater.
Product Overview
The 100288573 anode rod features a 3/4″ NPT hex fitting (HF) for straightforward installation and removal, and measures a full 40″ in length to provide maximum coverage inside the tank. Magnesium construction makes this rod ideal for use in water supplies with moderate to low mineral content, delivering superior sacrificial protection compared to aluminum alternatives in those conditions.

Why Replace Your Anode Rod?
Anode rods are a critical — and often overlooked — component of any water heater. As the sacrificial rod depletes over time, the tank itself becomes vulnerable to rust and corrosion. Regular inspection and timely replacement of the anode rod is one of the most cost-effective ways to protect your water heater investment and maintain peak performance.
