What should be done after achieving a net pump discharge pressure of 150 PSI during a pumping test?

After achieving a net pump discharge pressure of 150 PSI during a pumping test, it is essential to verify and possibly adjust the pressure for accurate data collection. Setting the net pump discharge pressure higher to 200 PSI allows for a more comprehensive evaluation of the pump's performance under varying pressure conditions. This is important for assessing the pump's capacity, efficiency, and operational limits.

Increasing the pressure to 200 PSI provides additional insight into how the system handles increased demands and can reveal potential issues that might not be evident at lower pressures. This adjustment plays a crucial role in understanding the overall water supply system’s capability for firefighting operations, ensuring that sufficient pressure can be maintained during emergencies.

Recording the water temperature, while important for some aspects of pump operation and system performance, does not directly contribute to understanding the pump's pressure capabilities. Consequently, adjusting the discharge pressure is a crucial step following the initial test results to fully assess the system's effectiveness.
