TROUBLESHOOTING CHART

Symptoms

Possible Cause(s)

Pump operates

1. Worn bearings

noisily or vibrates

2. Impeller broken

excessively

3. Piping attachments to building

structure too rigid or too loose

Pump will not

1. Switch

shut off

2. Switch obstructions

3. Restricted discharge (obstruction in

piping)

4. Excessive inflow or pump not

properly sized for application

Pump operates

1. Low supply voltage

but delivers little

2. Inlet screen clogged

or no water

3. Broken impeller

4. Pump not properly sized for

application

5. Check valve stuck closed or

installed backwards

6. Shut off valve closed

ROUTINE SUMP MAINTENANCE

The pump should be inspected 3-4 times per year for pump movement or buildup of debris on the switch or floar. Reposition

pump if it has moved. Remove any debris that could interfere with the operation of the switch. Lack of proper routine maintenance

will void warranty.

• Make sure the pump is plugged in to a working ground fault circuit interrupter (GFCI) outlet and the cord is in good shape.

In damp areas, GFCI breakers may trip, effectively shutting off the sump pump. Check in on your sump pump and reset the

GFCI if necessary.

• Ensure the pump itself is standing upright. Vibrations during operation can cause it to fall or tilt onto one side. This can jam

the float arm so it can't activate the pump.

• Pour a bucket of water into the pit to make sure the pump starts automatically and the water drains quickly once the pump

is on. If the pump doesn't start, have it serviced or replaced.

• Check the inlet screen and clear away any small stones or debris.

• Replace the switch every two (2) years. This maintence will reduce the risk of improper pump operation, switch failure and/

or flooding.
