• Connect the suction hose from the hydrant or the discharge of
another pumper to pressurize the pump with water and look for
visible leakage and correct. A pressure of 100 PSI (6.9BAR)
should be sufficient. DO NOT exceed pressure limitations of
pump, accessories or piping connections.
• The suction side relief valve can leak. Plug the valve outlet
connection and retest

• Engine power check and tune up may be required for peak engine
and pump performance.
• Also see heading “ROTATION SYSPTOMS” on page 60.
Relief valve improp-
erly set - if so
equipped
• If relief valve pressure is set too low it allows the valve to open
and bypass water.
• Reset the relief valve pressure accordingly.
• See Section 4 Preventive Maintenance, heading “Relief Valve
Suction hose diame-
ter is too small for

discharged
• Use larger sustain hose.
• Shorten total length by remove one length at a time.
• Reduce volume of discharge.
Restriction in suc-
tion line at strainer
• Remove any debris restricting entrance of water at the strainer.
• See Section 4 Preventive Maintenance, heading “Intake Strain-
Air leaks
• See heading “Air leaks” under condition “ Pump Loses Prime or
Partial collapse of
the lining in the suc-
tion hose
• Damage to the outer lining may allow air between the outer and
inner linings causing a partial collapse.
• Replace hose and retest.

Lift too high, suction
hose too small
• Higher than normal lift (10 ft./3.1m)) causes higher engine
speeds, high vacuum and rough operation.
• Use larger suction hose.
• Move the pump closer to the water source.
