If the discharge pressure drops below 50 PSI during drafting operations, what should the operator do?

In drafting operations, maintaining an adequate discharge pressure is critical for safe and effective water delivery. If the discharge pressure drops below 50 PSI, the proper action is to momentarily pause and monitor the situation rather than shutting down the pump or making drastic changes. This brief pause allows the operator to assess if the pressure is likely to stabilize or if there is a need for corrective action.

When the system is paused, the operator can listen for any changes in the pump or water supply signaling that the pressure might return to normal. It provides an opportunity to check for potential causes of the drop, such as air leaks, blockages, or issues with the water source. Engaging in a drastic change, like increasing engine RPMs prematurely or altering hose configurations, could exacerbate the situation by further destabilizing the flow or introducing additional complications.

Overall, the strategy to pause for a moment is based on maintaining operational stability and ensuring that any adjustments made afterward are well-informed and deliberate.
