What action is performed to verify the proper operation of water gauge glasses?

• A. Visual inspection
• B. Blowing down
• C. Calibrating
• D. Testing pressure

Answer: (B)

Blowing down is the appropriate action to verify the proper operation of water gauge glasses. This process involves opening a valve to allow water to be expelled from the gauge glass, which helps ensure that the water level indicated on the glass accurately reflects the actual water level in the boiler or other vessel. This action is crucial for safety and operational effectiveness, as it clears any obstructions that may affect the reading and confirms that the gauge glass is functioning correctly. Visual inspection, while important, does not provide a definitive confirmation of functionality like blowing down does. It may reveal obvious issues, such as cracks or leaks, but it cannot confirm the accuracy of the water level reading. Calibrating a water gauge glass is also important but typically occurs during maintenance rather than as a routine verification step. Testing pressure relates more to the operational safety of the system rather than validating the gauge glass's accuracy. Therefore, blowing down stands out as the most effective method to ensure that gauge glasses operate correctly, as it directly tests their ability to indicate water levels accurately.
