Verifying that all hand-operated valves are in their correct positions establishes a proper flow path for the pump. If valves are not oriented correctly, the pump can start without a clear suction or discharge route, leading to deadheading, backflow, or a dangerous pressure surge that can damage the pump, piping, or cause unsafe conditions. This immediate check confirms the system is actually ready to run and will operate as designed.

The other steps are important safety and preparation actions, but they don’t ensure the pump can start safely in the moment: consulting the manufacturer’s manual provides the correct procedures, locking out and tagging out protects workers during maintenance, and cleaning debris helps prevent blockages later. However, without the valves properly arranged, the startup itself could cause harm or equipment damage.
