Try cocks are used to verify what on a steam boiler?

• A. Verify water level
• B. Bleed air
• C. Measure steam output
• D. Drain condensate

Answer: (A)

The main idea is to confirm where the boiler’s water surface actually sits inside the boiler. Try cocks are small taps attached to the water space at different heights. When you open one, you watch whether water or steam comes out. If water appears, the water level is at or above that cock’s height; if steam comes out, the water level is below that height. By checking several cocks at known elevations, you can verify the exact water level and detect any discrepancy with the gauge glass. This helps prevent dangerous low-water or overfilling conditions. They aren’t used to bleed air, measure steam output, or drain condensate; those tasks use other devices.
