An overhaul in the context of inspections is specifically related to significant alterations made to a boiler system. The correct answer focuses on the threshold of changes that constitute an overhaul, which is defined as adding or demolishing more than 50 linear feet of piping. This level of modification is considered substantial enough to warrant a comprehensive inspection to ensure that the system operates safely and efficiently after the changes.

This aspect of an overhaul is critical because it implies that the structural integrity and the overall safety of the boiler system could be impacted by such modifications. Inspections following substantial alterations are essential in maintaining compliance with safety standards and ensuring proper functionality.

Other options, while relevant to boiler maintenance or operations, do not meet the criteria for what constitutes an overhaul. Painting a part does not significantly affect the operational performance or safety requirements. Performing yearly maintenance is part of routine upkeep and does not involve substantial changes to the system. Likewise, the installation of a new boiler is distinct from an overhaul, which typically pertains to existing systems undergoing considerable modifications rather than entirely new installations.
