Arkansas Boiler Operator Practice Exam

What is the main purpose of draining the glass gauge?

1. To check for leaks

2. To verify that the pipes to the drain are clean and open

3. To change the gauge

4. To adjust the water temperature

The correct answer is: To verify that the pipes to the drain are clean and open

Draining the glass gauge primarily serves to verify that the pipes leading to the drain are clean and open. This process ensures that there are no blockages or obstructions in the drainage system, which is vital for maintaining safety and efficiency in boiler operation. If the gauge is not drained periodically, sediment and debris can accumulate, potentially leading to inaccurate readings or preventing the safe removal of water from the boiler system. Ensuring that drain pipes are clear is essential for the reliable functioning of the boiler and to prevent any operational hazards. Proper maintenance through this practice contributes significantly to the overall health of the boiler system.
