What is a key reason to perform valve exercising regularly in a distribution system?

• A. To meet customer demands.
• B. To ensure operational readiness and prevent seizing.
• C. To design new pipes.
• D. To adjust water taste.

Answer: (B)

Regular valve exercising keeps valves operable and ready to isolate parts of the system when needed. By moving valves through their full range, it prevents seizing from corrosion, mineral buildup, or stiff stems and packing, and it verifies that valve position indicators are accurate. This proactive maintenance helps ensure reliable shutdowns during repairs or emergencies and catches wear or leaks early, extending valve life and reducing unexpected outages. The other options don’t address operational readiness or the ability to isolate sections of the system as needed.
