Q

When shifting suction from one fresh water tank to another, if the fresh water pump loses suction you should___________.

🔍 Key Concepts

• Centrifugal pump priming and what happens when a pump "loses suction" • Effect of air trapped in a pump casing and suction line • Proper sequence of troubleshooting: cause of lost suction vs. unrelated maintenance actions

💭 Think About

• Ask yourself: When you shift from one tank to another, what is the MOST LIKELY reason the pump suddenly loses suction? Think about what changed in the system. • Which action directly helps the pump move liquid again by restoring a solid column of water at the eye of the impeller? • Are any of the options more like long-term maintenance tasks rather than an immediate operational step to restore suction?

✅ Before You Answer

• Identify which choice deals directly with removing trapped air or vapor from the pump and suction line. • Decide which actions, if done unnecessarily, could damage the pump or have no real effect on suction loss in this situation. • Confirm which step would normally be done first by standard pump operating and priming procedures before checking other components.
