How should you perform a basic discharge valve check during an incident?

• A. Verify valve is fully open, ensure no leaks, monitor gauge readings, and confirm water is reaching the intended line
• B. Leave valve closed and observe
• C. Open all valves simultaneously
• D. Ignore gauges

Answer: (A)

During an incident, you must verify discharge valve operation to ensure reliable delivery and system safety. Start by confirming the valve is in the fully open position so there’s no unintended throttling that would restrict flow. Inspect for any leaks around the valve body, packing, or flanges, since leaks waste water, reduce available discharge, and can indicate seal or installation issues. Monitor the discharge line gauges to verify that pressure and flow are within the expected range for the situation, which provides real-time confirmation that the system is performing as intended. Finally, confirm that the discharged water is reaching the intended line or outlet, ensuring the downstream path is open and receiving the supply.

Leaving the valve closed would stop discharge entirely, opening all valves at once can cause pressure surges and instability, and ignoring gauges removes critical feedback needed to detect faults or abnormal conditions.
