1 . Plug the line to the control valve .
2 . Open the tester loading valve fully to read maximum pump flow at zero pressure .
3 . Close the loading valve to increase pressure from zero pressure to rated or maximum pump pressure to determine
pump condition .
4 . Check the pump flow at rated pressure against the pump manufacturer’s specifications . A decrease in flow from zero
pressure to maximum pressure indicates the pump condition . A pump that delivers a constant low flow at zero pressure
and at maximum pressure suggests suction problems .
