What is the consequence of not exercising valve operations during testing?

• A. Potential leaks or misoperation not identified
• B. Increased valve life
• C. No effect
• D. Color fade

Answer: (A)

Regularly exercising valves during testing is essential to ensure they will operate reliably when needed. Valves that aren’t exercised can become stiff from corrosion, deposits, or tight packing, and leaks can develop at seats or packing without being noticed. By actively turning and testing them, you confirm that each valve opens fully, closes fully, and seats correctly, and you catch any misoperation or leakage before an emergency. If this step is skipped, potential leaks or misoperation may go unidentified, risking improper isolation or control of the fire pump system when it’s needed most.
