TROUBLESHOOTING

Problem

Possible Cause

Corrective Action

A. Little or no

discharge

1. Casing not initially filled with water

1. Fill pump casing

2. Vertical lift too high, or too long

2. Move pump closer to water source

3. Hole or air leak in inlet line

3. Repair or replace inlet line. Use

thread tape and pipe sealing

compound

4. Foot valve too small

4. Match foot valve to piping or install

one size larger foot valve.

5. Foot valve or inlet line not

submerged deep enough in water

5. Submerge foot valve lower in water

6. Motor wired incorrectly

6. Check wiring diagram

7. Inlet or outlet line valves closed

7. Open valves

B. Pump will not

deliver water

or develop

pressure

1. No priming water in casing

1. Fill pump casing

2. Leak in inlet line

2. Repair or replace

3. Outlet line is closed and priming air

has nowhere to go

3. Open ball valve

4. Inlet line (or valve) is closed

4. Open line or valve

5. Foot valve is leaking

5. Replace foot valve

6. Inlet screen clogged

6. Clean or replace inlet screen

C. Loss of

suction

1. Hole or air leak in inlet line

1. Repair or replace inlet line. Use

thread tape and pipe sealing

compound

2. Vertical lift too high

2. Reduce vertical lift, install foot valve

and prime

3. Insufficient inlet pressure or suction

head

3. Increase inlet pressure by adding

more water to tank or increasing back

pressure

4. Clogged foot valve or strainer

4. Inspect foot valve and/or strainer for

debris, and remove

D. Pump

vibrates and/

or makes

excessive

noise
