FITS: Compatible with most water heaters that use a standard 3/4 inch NPT anode rod connection, including various models from State and other major brands. EXTEND LIFE OF YOUR WATER HEATER: The magnesium anode rod sacrifices itself to protect the tank from corrosion. It is recommended to inspect the anode rod every two years. Regular replacement may help extend the life of your water heater, providing long-term savings and reducing the need for premature unit replacement. ADVANTAGES OF MAGNESIUM ANODE RODS: Magnesium anode rods generate a stronger electrochemical current compared to aluminum, offering more effective protection against tank corrosion. This rod typically provides up to two years of protection depending on water conditions.
