After repairing a stuck priming valve, what is the recommended verification step before using the pump again?

• A. Immediately run the pump at maximum RPM.
• B. Retest priming and confirm water flow to pump.
• C. Seal priming valve and never test again.
• D. Drain the system completely.

Answer: (B)

After fixing a stuck priming valve, the essential step is to recheck the priming and confirm water is actually reaching the pump. This verification shows the priming path is clear, the valve seals properly, and the suction side is filled with water so the pump can create the necessary vacuum and draw water from the source. Without this check, you risk starting the pump with air in the suction, which can cause loss of prime, cavitation, or delayed firefighting capability. So, you retest priming and observe water flow into the pump to ensure it’s ready for service. The other options either risk damage, defeat the purpose of the repair, or waste time because they don’t confirm the pump is actually primed and capable of delivering water.
