Basic Operation 
Note: If no valve is present, you must watch the intake gauge for a high-pressure reading. If
necessary, open the gate controlling the uncapped discharge to dump excess water on the
ground and reduce pressure.
3. Supply the pump at the water source with water; prime if necessary.
4. The discharge pressure must not exceed 185 PSI (1,276 kPa) for 5” (125 mm)
large diameter hose, or 135 PSI (931 kPa) for 6” (150 mm) hose, per NFPA Stan-
dards 1962. See heading “Pumping From a Hydrant, General Operation” on page
54. Also see heading “Pumping From Draft” on page 58.
IMPORTANT!
FOR ADDITIONAL SUPPLY HOSE AND PRESSURE SETTING INFORMATION, SEE NFPA
STANDARDS 1962.
5. When the water reaches the second pump, close the uncapped discharge gate.
Repeat this step for all pumps until the water reaches the fire ground.
6. Adjust the throttle on the pump at the water source for the required operating
pressure. Watch the gauges to avoid cavitation.
Also see heading “Cavitation” on
page 193.
7. The pump operator at the fire scene must advise all other pump operators of the
amount of water needed at the fire ground.
8. Adjust the discharge pressure or flow at the fire scene to supply the lines being
used.
9. Observe the gauges carefully, and adjust the pressure or flow as needed.
10. Shutdown starts from the fire ground pump and works toward the water source.
Gradually reduce pressure at the fire ground pump until you can disengage the
pump.
11. Follow this procedure for every pump in the relay until the pump at the water
source is shut down.
