How should an inspector assess the age and condition of a water heater?

The most effective way for an inspector to assess the age and condition of a water heater is by checking the serial number, visual condition, and signs of leakage or corrosion. The serial number often contains information about the manufacturing date, which helps determine the age of the unit. The visual inspection allows the inspector to identify any physical signs of wear, such as rust, corrosion, and leaks, which can indicate the overall condition and potential issues that may require attention or replacement.

While examining the water heater's location can provide context and could affect its operation and longevity, it does not directly inform the inspector about the unit's age or condition. Energy efficiency ratings are relevant to the performance-based assessment of the water heater, but they do not give specific information regarding its current working condition or age. Investigating the manufacturer's reputation may offer insights into the brand's reliability and lifespan expectations, but it does not replace the necessity of directly assessing the starter data through the serial number and physical inspection. Thus, a combination of these factors topped by a focused inspection yields a comprehensive view of the water heater's status.
