Try cocks for a boiler are attached to which component?

• A. Water Column
• B. Boiler Drum
• C. Chimney
• D. Firebox

Answer: (A)

Try cocks are small sampling valves used to draw boiler water samples to check water quality. They’re attached to the water column, the vertical gauge assembly on the boiler that shows the water level and provides access for sampling. This location lets you take representative samples from the boiler water without draining the boiler, which is essential for confirming impurity levels, hardness, and other characteristics that affect scale and corrosion. The boiler drum, chimney, and firebox have roles in steam generation and combustion, not in sampling boiler water, so the try cocks aren’t mounted there.
