Which of the following is NOT a type of service or maintenance commonly required for boilers?

Regular pressure checks
Metal fatigue inspections
Water quality tests
Carpet cleaning

The correct answer is: Carpet cleaning

The choice of carpet cleaning is not associated with the essential service or maintenance tasks that are required for the operation and safety of boilers. Regular pressure checks help ensure that the boiler operates within its designed parameters, which is crucial for preventing failures or dangerous situations. Metal fatigue inspections are performed to assess the integrity of the boiler's structural components, identifying any weaknesses that could lead to catastrophic failures. Water quality tests are vital in preventing issues such as scaling or corrosion, which can significantly impact the efficiency and safety of the boiler. In contrast, carpet cleaning pertains to maintaining cleanliness and aesthetic appeal in a facility but has no relevance to the mechanical operation or safety of boiler systems. Therefore, it stands out as unrelated to common maintenance practices for boilers.
