How often should pump suction, discharge, and by-pass valves be visually inspected?

• A. Daily
• B. Monthly
• C. Weekly
• D. Annually

Answer: (C)

Regular visual checks of pump suction, discharge, and by-pass valves are about spotting small issues before they become big problems—things like minor leaks at packing, corrosion, dirt or debris in the valve seats, or valves that don’t move freely. Doing this check on a weekly basis strikes a practical balance: it’s frequent enough to catch developing problems early, such as a packing that’s starting to leak or a valve that’s sticking, while not requiring the labor of daily inspections for every valve. If the bypass is left open or the valve position isn’t what it should be, it can lead to improper flow or spills, so a weekly glance helps confirm the system is in the intended state. Daily checks would be overly burdensome for routine valves, and monthly or annual checks can allow leaks or wear to go unnoticed.
