FITS: Almost all water heaters that use the standard 3/4 inch NPT anode rod connection. EXTEND LIFE OF YOUR WATER HEATER: Magnesium anode rods corrode faster than the tank, acting as a sacrificial component. It is recommended to inspect the magnesium anode rod every two years. Regular replacement may help extend the life of your water heater, potentially saving time and money on premature replacements. ADVANTAGES OF MAGNESIUM ANODE RODS: Magnesium anode rods generate a stronger electrochemical current compared to aluminum rods, offering more effective protection against tank corrosion. This anode rod typically provides up to two years of protection.
