A Bradford White sacrificial anode rod should typically be inspected every two to three years and replaced as soon as it shows significant depletion, which generally occurs between three and five years depending heavily on local water hardness. In aggressive hard water conditions or areas with high mineral content, the anode rod sacrifices itself to protect the inner steel tank from rusting and can deplete much faster, requiring inspection every year. Checking and replacing the anode rod proactively prevents premature tank corrosion and can double the total operational lifespan of your water heating system.
