Where should the pressure sensing line connection for each pump be located in relation to the discharge check valves?

The pressure sensing line connection for each pump should be located between the pump discharge and the discharge check valves. This placement is crucial because it ensures that the pressure readings reflect the actual pressure generated by the pump without being influenced by any back pressure that may occur downstream of the check valves.

When the pressure sensing line is connected between the pump and the check valves, it accurately measures the pressure that the pump is producing to ensure proper operation and performance. If the pressure sensing line were placed after the check valves, the readings could be affected by any resistance or back pressure in the system, leading to inaccurate readings that could lead to operational issues. Likewise, placing it before the check valves would provide misleading information about the discharge pressure; any backflow could interfere with the reading. Thus, the positioning of the pressure sensing line between the pump and the check valves is essential for reliable performance monitoring and control.
