TROUBLESHOOTING
TROUBLESHOOTING
1. No power.
2. Pressure switch disconnected.
3. Thermal protection activated.
4. Blocked impeller.
1. Pump not primed.
2. Lift height exceeded.
3. Inlet tube not submerged.
4. Air in suction pipe.
5. Inlet screen clogged.
The pump
won't start.
The pump
operates but
it won't
discharge
water.
1. Check connections, and breaker/fuse.
2. Check gauge.
3. Allow pump to cool.
4. Free the impeller.
1. Prime pump.
2. Reduce lift height.
3. Submerge the inlet.
4. Check pipe and seals.
5. Clean screen.
Problem
Possible Cause
Corrective Action
1. Inlet pipe is too small.
2. Liquid is too dirty.
3. Lifting height exceeded.
4. Tank's rubber bladder
under-inflated.
5. Piping corroded, causing friction.
1. Extension cord too long or wire
size too small.
2. Pump cycling too often.
1. Increase pipe diameter.
2. Clean screen frequently.
3. Reduce lifting height.
4. Inflate to 23 PSI.
5. Replace piping with plastic where
possible.
1. Eliminate use of extension cord or use
shorter/heavier gauge cord.
2. Cut-in and cut-out pressure may be set
too close together. Have the pressure
switch adjusted by a qualified technician.
Cut in and cut out pressure may be
set too closely.
1. Air inlet valve is leaking.
2. Bladder is broken.
Have the pressure switch adjusted by
a qualified technician.
Water level is being drawn below
foot valve.
Lower foot valve.
1. Check air tank for leaks using soapy
water and replace bladder if needed.
2. Replace bladder.
• Follow all safety precautions whenever diagnosing or servicing the pump.
• Disconnect power supply before service.
• Do not disassemble the pump or motor as this will damage the water seals.
• All repairs should be performed by a qualified technician.
1. Pumping bubbles temporarily as
air is purged after initial setup.
2. Leak in suction side of pump
system.
3. Well is gaseous.
4. Water level below suction inlet
of foot valve.
Water is full
of bubbles
at outlet.
1. Temporary self-remedying issue.
2. Check for and fix leaks.
3. Install a sleeve in the well.
4. Lower suction line into water and
re-prime. If water is lower than the
maximum suction lift height, a deep
well pump may be needed.
