Troubleshooting
This section provides brief troubleshooting instructions for verifying the set-up and
operation of the pump. Each section describes a condition and lists possible causes along
with a list of items to check to identify the source of the problem and resolve it.
Pump Loses Prime or Will Not Prime
Air Leaks
Attempt to locate and correct the air leaks by isolating each system component.
Verify that the suction hose is in good condition and is properly tightened.
Verify that the suction hose gasket is in good condition.
Air Trapped in
Suction (Pump
Intake) Line
Check that no part of the suction hose or piping is higher than the pump intake.
Pump suction hose and piping must be laid out with a continuous decline to the
water source from the pump intake
Long Suction
Hose with High
Lift
While running the pump, verify if the suction hose is being filled.
If the water level has stopped rising, the water level inside the pump body was
totally discharged. Re-fill the pump body and try again.
Partially restricting the discharge hose will improve priming time.
Blocked or
Restricted
Intake Hose or
Strainer
Remove blockage from the intake hose or strainer.
Strainer should not be sitting at the bottom of the water source where debris can
be picked up. Clean off the strainer and raise to a position that is off the bottom
of the water source (floating strainers are available).
If the strainer is new, check that the strainer hole size is not too restrictive for the
demands of the pump.
Pump Suction
Lift
Requirements
are Too High
DO NOT attempt pump lifts exceeding 16 feet (5 meters). Higher suction lifts will
negatively impact the flow rate and could lead to cavitation.
As elevation increases above 2000 feet above sea level, maximum lift heights
will diminish. Check that the lift for the elevation the pump is being required to
operate at is achievable.
Defective/
Obstructed
Suction Flap
Valve
Verify that the suction flap valve is operating freely and is not obstructed or
damaged.
Pump Does Not Meet Performance
Incompatible
Installation
Piping size and configuration may be too restrictive. Contact a WATERAX
Inc. representative if assistance is needed in evaluating the unit’s piping.
Gauge or
Instrument
Failure
Check that all gauges are calibrated and that all equipment is in proper
condition. Nozzles with dented edges and bent or damaged pitot tubes will
produce faulty readings.
Blockage
Check all hoses, tank, piping, etc. Remove any obstructions found.
Check for debris wedged or caught in the impeller or diffusers. Remove any
obstructions found.
Insufficient
Power to the
Pump
Check engine compression and complete engine repairs if required.
An engine tune up may be needed to bring engine back to peak
performance.
