PUMP WILL NOT START/ BLOWS CIRCUIT:
•
Electrical connections, fuse or breaker, main switch, and ground
connection.
•
Is the motor hot? Thermal breaker may have triggered; it will reset
when cool.
•
Is voltage present at the switch? Bypass the pressure switch.
Does the pump operate?
•
Charging System for correct voltage (±10%) and good ground.
•
For an open or grounded circuit, or motor; or improperly sized
wire.
•
For seized or locked diaphragm assembly (water frozen?).
WILL NOT PRIME/SPUTTERS:
(No discharge/Motor runs)
•
Is the strainer clogged with debris?
•
Is there water in the tank, or has air collected in the hot water
heater?
•
Is the inlet tubing/plumbing sucking in air at plumbing connections
(vacuum leak)?
•
Is inlet/outlet plumbing severely restricted or kinked? Restrictive
valves?
•
Proper voltage with the pump operating (±10%).
•
For debris in pump inlet/outlet valves or swollen/dry valves.
•
Pump housing for cracks or loose drive assembly screws.
RAPID CYCLING:
•
For restrictive plumbing and flow restrictions in faucets/shower
heads.
•
Water filter/purifier should be on separate feed line.
•
Shut-off pressure set too low.
PUMP WILL NOT SHUT-OFF / RUNS WHEN FAUCET IS CLOSED:
•
Output side (pressure) plumbing for leaks, and inspect for leaky valves
or toilet.
•
For air trapped in outlet side (water heater) or pump head.
•
For correct voltage to pump (±10%).
•
For loose drive assembly or pump head screws.
•
Are the valves held open by debris or is the rubber swollen?
•
Pressure switch operation. By -pass set higher than shut -off
NOISY OR ROUGH OPERATION:
•
For plumbing which may have vibrated loose.
•
For a restricted inlet (clogged strainer, kinked hose, restrictive
valves).
•
Is the pump plumbed with rigid pipe causing noise to transmit?
•
Does the mounting surface amplify noise (flexible)? Does it bang
like a drum?
•
For mounting feet that are loose or are compressed too tight.
•
For air in the system. Check all fixtures for air and bleed system.
•
The motor with pump head removed. Is noise from motor or pump
head?
LEAKS FROM PUMP HEAD OR SWITCH:
•
For loose screws at switch, by -pass or pump head.
•
Switch diaphragm ruptured or pinched.
•
For punctured diaphragm if water is present in the drive assembly.
Troubleshooting
Vibration induced by driving can loosen plumbing, strainers and pump hardware. Check for system
components that are loose. Also, refer to the chart below for trouble-shooting tips.
