Make sure your pump has a pressure gauge on the discharge side close to the outlet of the pump this will help you diagnose pump system problems. It is also useful to have a pressure gauge on the suction side, the difference in pressure is proportional to the total head.

The pressure gauge reading will have to be corrected for elevation since the reference plane for total head calculation is the suction flange of the pump. Most centrifugal pumps cannot run dry, ensure that the pump is always full of liquid.
