What should be checked first when inspecting a water heater installation?

When inspecting a water heater installation, the first step should be to verify compliance with local codes. This is crucial because local codes and regulations are established to ensure safety, performance, and environmental standards are met. Each jurisdiction may have specific requirements regarding installation practices, necessary permits, and safety features, such as the placement of venting systems, clearances from combustibles, and seismic restraints.

Ensuring compliance helps prevent potential hazards, such as gas leaks or water damage, and guarantees that the installation adheres to the standards necessary to protect occupants and property. Moreover, if the installation does not comply with local codes, it may lead to costly corrections, fines, or even legal liabilities, making this the most critical aspect to address first in an inspection.

While aspects such as energy efficiency, fuel type, and warranty are important considerations, they typically come after confirming that the installation adheres to applicable laws and standards.
