What should be done if the pump has not been primed in the specified time?

When the pump has not been primed in the specified time, it is crucial to stop the operation and check for problems or air leaks. This is the most prudent course of action because failing to prime the pump can indicate underlying issues that need to be addressed before continuing. Checking for problems or air leaks allows the operator to identify potential causes for the failure to prime, such as loose fittings, cracks in the hoses, or other mechanical failures that could compromise the pump's performance.

By stopping and assessing the situation, the operator can ensure safety and reliability before attempting to prime the pump again. Continuing to try to prime the pump without addressing these issues may lead to further complications, inefficiencies, or damage to the equipment. Adjusting the RPM of the engine or resetting the system without first diagnosing the problem does not address the root cause and could lead to repeated failures in the priming process.
