3. Attach sufficient hose lines and nozzles to pump the desired discharge
rate.
4. With the pump in gear, open the discharge to which the hose is attached
and begin pumping water.
5. Increase the engine throttle until the maximum consistent pressure is
obtained on the discharge gauge.
6. Close the discharge valve without changing the throttle setting. Refill the
tank through the top fill opening or a direct tank line. The bypass valve
may be opened during this time to prevent pump overheating.
7. Reopen the discharge valve and check the flow through the nozzle using
a Pitot tube or flow meter. Adjust the engine throttle to bring the pressure
to the amount previously determined.
8. Compare the flow rate measured to the NFPA minimum or the designated
rate of the pump. If the flow rate is lower, a problem may exist in the tank-
to-pump line. The minimum flow rate should be continuously discharged
until 80% of the tank is discharged.
9. The pump should not experience mechanical problems, power loss, or
overheat during the test.
Performance Testing Equipment and Materials
To accurately test pumper performance, a Pitot Gauge, a calibrated pump mas-
ter pressure gauge, and a master vacuum gauge or manometer are required.
ALL gauges must be carefully tested for accuracy. Gauge testing is appropri-
ately accomplished with a certified dead weight gauge tester.
