MAINTENANCE

LUBRICATION
The pump requires only water for lubrication and must
never be run dry.
DRAINING
If your pump must be drained for service or to prevent
freeze damage, remove the discharge fitting and the drain
plug from the pump case. Note: while this will drain the
pump, it will not necessarily drain all the unprotected
parts of the piping system. To drain tank, disconnect the
piping at the tank outlet.
The air volume control can be drained by unscrewing
fitting and turning control upside down. This will allow
water back into tank where it will drain. All piping exposed
to freezing should be drained.
C A U T I O N
Do not run pump after being drained.
TROUBLESHOOTING GUIDE
Problem
Motor will not start
Motor overheats
Gravelly noises inside pump (cavitation)
Loss of pressure when no water is used
Pump does not deliver water
or pressure
Low pressure (if pump delivers
water but at a low pressure)
Low capacity
Air logging (excessive air in pipe)

SERVICING AND DISASSEMBLY

breaker box leads are disconnected or power is
turned off. After reassembling the pump, refer to
priming instructions before running pump.
If you experience problems with your pump, determine
the trouble using "Troubleshooting Guide". If shallow well
injector needs servicing, it can quickly be removed from
pump without disturbing pump or piping. If impeller,
motor, or seal need servicing, disconnect the pressure
line from pressure switch and remove bolts holding
bracket to pump case. Take off motor and bracket
assembly; do not disconnect pipes. This will expose
impeller. Unscrew impeller from shaft to reach seal.
Reassemble in reverse order. Clean square ring and
sealing surfaces and lightly lubricate to aid in assembly.
Possible Cause
1. Open switches, blown fuses or
loose connections.
2. Improper connections to motor.
1. Improper voltage or wiring connections.
2. Pump is operating at too low a
discharge pressure.
3. Improper ventilation for motor.
1. Water level below 25'.
2. Suction pipe diameter is too small or length
of pipe too long.
3. End of suction is mud or sand.
4. Discharge pressure too low.
1. Leaks in piping or valves.
2. Gas in water.
3. Water level drops below the end of the pipe.
1. The pump is not full of water.
1. The motor is not up to speed.
2. The impeller or injector nozzle is
partially plugged.
3. Air is leaking into the suction line.
1. Water level is deeper than 25'.
2. Using too long a pipe from the water to
the pump.
3. Plugged impeller or injector nozzle.
4. The pipe from the pump to the water is
partially plugged.
1. Air leaks in pipe.
2. Gas in water.
3. Water level drops below the end of the pipe.
C A U T I O N
When disconnecting pump, be sure
1. Check switches, fuses, and connections.
2. Make sure connections are tight.
1. Check to see if your voltage is the same as
indicated on motor plate. Be sure all wiring
connections are tight.
2. Cut back control valve gradually until
operation is constant.
3. Check to see if motor is clean.
1. Call your dealer.
2. Use a larger diameter pipe.
3. Raise end of suction pipe or clean out well.
4. Change control valve gradually until trouble
is corrected.
1. Check connections.
2. Call your dealer.
3. Pump is out-producing the well. Close down
control valve gradually until pump starts
operating properly.
1. Stop the pump, fill with water, check
all pipe connections to make sure there are no
air leaks and try again.
1. See if you have proper voltage
and tight wiring connections.
2. Check impeller or nozzle for rocks or debris.
Refer to disassembly instructions for getting
to impeller.
3. Check suction line connections.
1. Pumping level cannot pump below 25'.
Call dealer.
2. Use a larger diameter pipe.
3. Check impeller and nozzle. Refer to
disassembly instructions.
4. Check pipe.
1. Check connections.
2. Call your dealer.
3. Pump is out-producing the well. Close down
control valve gradually until pump starts
operating properly.
