How often should the anode rod be checked for corrosion?

The anode rod in a hot water tank is a critical component designed to prevent corrosion by attracting corrosive elements in the water. Checking the anode rod for corrosion every three years is recommended because it allows for timely detection of any deterioration. If the anode rod is severely corroded or depleted, it may no longer provide adequate protection to the lining of the water heater tank, potentially leading to leaks and failure.

Regular inspections every three years can help identify issues before they escalate, extending the lifespan of the water heater and ensuring it operates efficiently. This timeframe strikes a balance between being frequent enough to maintain the system's integrity and cost-effective, preventing unnecessary wear and tear or replacement of the anode if it remains in good condition.
