c. Fiberglass Drive Rod Disconnected
• Remove the pumping system from the well
• Verify that the fiberglass drive rod is connected to the driver and to
the piston
⸰ If fiberglass drive rod is separated at the compression fitting, a
replacement drive rod ferrule will be required (ferrules cannot be
re-crimped)
• Remove pump system from the well
• Clear debris from the pump barrel, foot valve, piston, and riser pipe
⸰ Debris or obstuctions can cause the check ball to not be seated
properly, preventing a proper seal in either the piston or the foot
valve
• Perform the glove test (see below) to determine if intake is plugged
• If intake is plugged because it was placed in mud or silt, raise the
pump system so that the intake is clear of the mud or silt
d. The Liquid Level Has Dropped Below The Intake
• Measure the liquid level of the well

THE GLOVE TEST
⸰ Remove discharge
line from tee
⸰ Firmly wrap a rubber glove around the discharge tee, sealing it
with your hand or a rubber band
⸰ If the glove slowly inflates during actuation, then the pump is
raising liquid to the surface and displacing the air in the riser pipe
⸰ If the glove breaths in and out then there is liquid in the riser pipe
but the pump barrel is clogged
⸰ If the glove does not inflate then refer to issues b-d in the previous
