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 above.
2. Pump's inlet is partially blocked. Check to make sure the inlet is clear of debris.
3. Discharge line is partially blocked. Check line for blockage.
4.
Check valve is not opening all the way. Check for defective, reversed, 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.
Motor or switch may be defective. Consult factory.
PUMP SPRAYS WATER FROM SIDE OF HOUSING.
1. This is normal due to factory drilled air-bleed hole and is not cause for concern.
5.
Maintenance
1.
Submersible Models: Submersible pump models have sealed permanently lubricated bearings and require
no additional lubrication.
2.
Pump should be checked frequently for debris and/or build up which may interfere with pump or float
switch operation. The float must be able to move freely through its complete travel without any restrictions.
Pour enough water into the sump to activate the pump periodically (at least every 3 months) when not
normally in use to verify proper function.
3.
Pedestal Models: Pedestal sump pumps have open, exposed motors. 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 C. Pour enough water into the sump pit to
activate the pump periodically (at least every 3 months) 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.
