Troubleshooting 7
Symptom Probable Cause(s) Corrective Action
Failure to pump.
Pump not properly primed.
Make sure pump body is full of water. See priming
instructions.
Speed too low.
Check voltage at motor terminals and at meter when pump is
operating. If low, refer to wiring instructions, or check with
your Power Company. Check for loose connections.
Total head too high. A pump designed for high head service is needed.
Suction lift too great.
Locate pump closer to source of water. Make sure suction
piping is large enough.
Excessive air leak in suction line. Check and repair suction line.
Water level drops while pumping, uncovering
suction inlet.
Check water supply. Add pipe to suction to keep it
submerged.
Reduced capacity and/or head (pressure).
Air pocket or leaks in suction line. Check suction piping.
Clogged impeller. Remove and clean.
Foot valve strainer too small, or clogged. Use larger foot valve, clean.
Insufficient submergence of suction pipe.
Add lengths of suction pipe to keep it well below the water
surface.
Excessive dynamic suction lift (over 20 ft.).
If caused by suction pipe friction, enlarge piping and foot
valve. Otherwise move pump closer to water level.
Total head (pressure) more than that for which
pump was intended.
A larger pump is needed.
Excessively worn impeller.
Order replacement parts, using repair parts list in this
manual.
Mechanical troubles and noise.
Suction and/or discharge piping not properly
supported and anchored.
See that all piping is supported to relieve strain on pump
assembly.
Motor runs hot and overload kicks off.
Check the voltage dial on the motor to set it to the correct
input voltage.
