This guide is designed to help identify reasons for
potential operating problems. It is not a service
guide.
DISMANTLING OF PUMP VOIDS WARRANTY.
Servicing of pump other than simple cleaning of
pump inlet or impeller should be referred to the
factory or its authorized service centers.
NOTE: The manufacturer assumes no
responsibility for damage or injury due
to disassembly.
PUMP DOES NOT RUN OR HUM:
1) Line circuit breaker may be off, tripped or
loose. Have a certifi ed electrician check fuse or
breaker.
2) Water level in pit may be too low to activate
switch. Add more water to pit.
3) Plug on power cord may not be making contact
in receptacle. Check security and connection.
4) Float may be obstructed. Make sure fl oat is free
and not interfering with the pit wall or other
obstruction.
5) If all symptoms check OK, the motor winding
may be open. Consult factory.
PUMP RUNS OR HUMS BUT DOES NOT
DELIVER WATER:
1) Check valve may be installed backwards or
is defective. Check to make sure it is installed
properly and fl apper in valve is free to move.
2) Discharge line may be blocked or frozen. Check
to see if line passes through cold areas or is
blocked.
3) Pump may be air-locked. Make sure air bleed
hole was drilled in discharge pipe. See Figure A
for proper location of bleed hole.
4) Vertical lift is beyond pump's capability. Pump's
maximum lift capability is 17'.
NOTE: At the pump's maximum lift there will be
no fl ow.
5) Inlet screen of pump is plugged or the impeller
is jammed. Remove the pump screen and clean
inlet and impeller.
PUMP RUNS AND REMOVES WATER BUT
DOES NOT SHUT OFF:
1) Float is stuck in the "ON" position. Check to
make sure the fl oat is free to move up and down
without obstruction.
2) Switch is defective. Consult factory.

PUMP RUNS BUT DELIVERS VERY LITTLE
WATER:
1) Vertical lift is approaching the pump's
maximum lift capability. Refer to the above
maximum lift chart.
2) Pump's inlet is partially blocked. Check to make
sure the inlet is clear of debris.
3) Discharge line is partially blocked. Check for
blockage.
4) Check valve is not opening all the way. Check
for defective or blocked check valve.
CIRCUIT BREAKER TRIPS OR FUSE BLOWS
WHEN PUMP STARTS:
1) Fuse or breaker size is too small. A 15 amp
breaker should be used.
2) Other major appliances are on the same circuit.
Pump should be on its own circuit.
3) Pump is connected to an extension cord or
wiring is inadequate. Have an electrician check
for proper wiring.
4) Defective motor or switch. Consult factory.

Maintenance

• Pedestal sump pumps have open, exposed mo-
tors. Take precautions to make sure the motor
does not get wet from dripping pipes, etc.
• Pour an ounce of 20 or 30 weight oil into the
hole near the top of the pedestal column every
6 months. A label next to the hole designates
where to add the oil. See Figure B.
• Pour enough water into the sump pit to activate
the pump periodically when not normally in
use.
• Check periodically to make sure the pit is free
from accumulated debris, rocks or other objects
that may potentially jam the pump.
