• Punctured pump diaphragm.
• Defective pump check valve.
• Crack in pump housing.
• Debris in check valves.
• Missing or damaged o-ring of control valve chamber.
• Pinched/kinked hose.

Motor fails to turn on
• Pump or equipment not plugged in electrically.
• Loose wiring connection.

• Depletion of available liquid supply.
• Punctured pump diaphragm.
• Discharge line leak.
• Defective pressure switch.
• Insufficient voltage to pump.
• Debris in check valves.
Low flow and pressure
• Defective check valves (most cases).

PREVENTATIVE MAINTENANCE TIPS
If pumping a liquid other than water, the pump should be flushed
with water (if applicable) after each use. Sealers and Teflon tape act-
ing as a lubricant can cause cracked housings or stripped threads
due to over-tightening. Care should be used when applying seal-
ers; the tape may enter the pump, thus inhibiting valve action and
causing no prime or no shut-off conditions. Failures due to foreign
debris are not covered under warranty.
Before freezing conditions occur, the pump must be liquid free or
winterized with proper anti-freezing chemicals. If mounting the
pump in an outdoor environment, the pump should be shielded
from water, dust, sunlight, and washdown spray. Do not assume
chemical compatibility. If the fluid is improperly matched to the
pump's elastomers, the pump may fail to prime, have low pres-
sures, or the pressure switch may not shut off.
Contact your supplier for advice.
