MAINTENANCE

Poppet Check Valve

Use a T-Handle Poppet Wrench (part no. 106964101), 
ordered separately, or standard needle nose pliers to 
remove the poppet assembly by turning clockwise.
If reinstalling, tighten to 15 inch-pounds.

Troubleshooting

Risk of damage to pump or other equipment.

Fluid draining back through the pump can cause the pump to rotate backwards. If pump/motor starts during this time, damage to 

the pump can occur.

Problem

Probable Causes

Corrective Action

Pump fails to start

Electrical trouble

Call dealer or electrician

Draw-down protection device 

has pump turned off

Make sure system check valves are correctly installed or uninstall draw-down 

protection device. Reset low pressure cutoff switch (if installed).

Overload tripped

Reset overloads and low pressure cutoff switch (if installed).

Pump fails to deliver 

water or reduced out

put

Clogged intake screen

Clean intake screen.

Insufficient well yield

Shut off system. Refer to 

“Low-Yielding Well” on page 4

.

Worn pump

Replace pump.

Low voltage

Make sure the power supply corresponds with the electrical rating of the 

motor. For 3-wire, single phase pumps, check the control box.

Incorrect rotation (3-phase)

Interchange any two leads at the magnetic starter.

Pump cycles too fre

quently

Pressure drop between pres

-

sure switch and tank.

Check system for a plumbing leak and correct as necessary.

“Cut-in” or “Cut out” pressure 

too high.

Follow manufacture’s instructions to properly set the on/off cycle of the pres

-

sure switch.

Waterlogged pressure tank

Follow manufacturer’s instructions on resetting/establishing proper air pres

-

sure setting for the tank.

Electrodes of floatless liquid 

level control too close together.

Follow manufacture’s recommendation for installation of the electrodes on 

the level control.

Tank too small.

Install pressure tank with bonded diaphragm, air cell, or water bag.

Overloads trip

Electrical trouble

Call dealer or electrician.

Pressure switch cycles 

rapidly

Pressure switch too far from 

pressure tank

Adjust air charge of tank to manufacturer’s recommendations.

Backspin

Failed or no check valve

Install new, non-swing type check valve(s).

Upthust

Check valve drilled

Install positive sealing check valves only.

Water Hammer

Lowest check valve leaks or is 

more than 30 ft above water

Shut system down and contact pump installer to correct issue.

Check valve drilled
