GENERAL SAFETY INFORMATION
1. Follow all local electrical and safety codes, as well
as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
2. Replace damaged or worn wiring cord
immediately.
3. Do not kink power cable and never allow the cable
to come in contact with oil, grease, hot surfaces, or
chemicals.
4. Protect the power cable from coming in contact
with sharp objects.
5. Be careful when touching the exterior of an
operating motor - it may be hot enough to be
painful or cause injury.
6. Make certain that the power source conforms to
the requirements of your equipment.
7. Always disconnect power source before
performing any work on or near the motor or
its connected load. If the power disconnect point
is out-of-sight, lock it in the open position and tag
it to prevent unexpected application of power.
Failure to do so could result in fatal electrical
shock.
8. Do not handle the pump with wet hands or when
standing in water as fatal electrical shock could
occur. Disconnect main power before handling
unit for ANY REASON!
9. Unit must be securely and adequately electrically
grounded. This can be accomplished by wiring the
unit to a ground metal-clad raceway system or by
using a separate ground wire connected to the bare
metal of the motor frame or other suitable means.
10. RISK OF ELECTRIC SHOCK. These
pumps have not been investigated for use in swim-
ming pool areas.
11.
This product contains chemicals known
to the State of California to cause cancer and birth
defects or other reproductive harm.
NOTE: Pumps with the “UL” Mark and pumps with the
“US” mark are tested to UL Standard UL778.CSA certied
pumps are certied to CSA Standard C22.2 No. 108.
LOCATION
1. Pump can be located at the well or can be offset
some distance away from the well. For best
performance it should be located as close to the
well as possible.
2. Location can be in the basement, a pit below
ground, or in a pump house above ground.
3. Ventilation and drainage must be provided to
prevent damage from moisture to the motor and
pressure switch.
4. The pump and all piping must be protected from
freezing.
5. Pump and pipe line must be drained when not in
use if there is any danger of freezing.
WELL CONDITIONS
1. Wells should be pumped clean of all sand and
foreign matter before installing the pump or
damage may result to the operating parts.
2. The well must be able of supplying enough water
to satisfy the capacity of the pump and water
needs. The water level must not draw down below
the maximum rated suction lift of the pump or loss
of capacity and prime will result.
SUCTION LIMITATIONS
1. Shallow well installation is satisfactory where the
suction lift is less than 25 feet. Suction lift is the
vertical lift plus losses due to friction loss.
2. Suction lift varies depending upon elevation
(altitude) and water temperature.
OWNERS GUIDE TO INSTALLATION AND OPERATION
READ THESE INSTRUCTIONS CAREFULLY
Read these installation instructions in detail before installing your pump. Be sure to check the following:
1. Be certain the motor is connected for the correct line voltage being used (check motor nameplate).
2. Be certain the pump is completely primed before starting. Otherwise damage may occur to the seal.
Every pump is tested before leaving the factory, and its performance depends largely on the installation.

Questions and Answers

    What to do if my Flint & Walling Water Pump will not start or run?
    • M
      Morgan WhiteAug 7, 2025
      If your Flint & Walling water pump refuses to start or run, begin by checking the wiring diagram on the motor to ensure it's properly wired. Look for a blown fuse or open circuit breaker and replace the fuse or close the breaker. Inspect for loose or broken wiring, tightening connections or replacing damaged wires. A stone or foreign object lodged in the impeller can also prevent starting; disassemble the pump and remove any obstructions. If the motor is shorted out, it will need to be replaced. Lastly, if the thermal overload has opened the circuit, allow the unit to cool before restarting, after identifying the cause of the overload.

    Why won't my Flint & Walling Water Pump deliver water or develop pressure?
    • T
      timothy61Aug 18, 2025
      If your Flint & Walling water pump won't deliver water or develop pressure, consider these possibilities: ensure there is priming water in the casing by filling it; check for a leak in the suction line and repair or replace if necessary; make sure the discharge line is open so priming air can escape; verify the suction line or valve is open; the pump may be down (replace worn parts); the foot valve may be leaking (replace it); or the suction screen may be clogged (clean or replace it).

    What causes a Flint & Walling Water Pump to lose suction?
    • H
      Henry HodgesAug 25, 2025
      A loss of suction in your Flint & Walling water pump can be attributed to several factors. Check for an air leak in the suction line and repair or replace if needed. The suction lift may be too high, in which case you should lower it, install a foot valve, and prime the pump. Insufficient inlet pressure or suction head can also cause this issue; increase inlet pressure by adding more water to the tank or increasing back pressure. Finally, a clogged foot valve or strainer can lead to suction loss; unclog it to resolve the problem.

    How to fix a Flint & Walling Water Pump that vibrates and/or makes excessive noise?
    • M
      Michael LeeAug 30, 2025
      Excessive noise and vibration in your Flint & Walling water pump could stem from several issues. Start by checking if the mounting plate or foundation is not rigid enough and reinforce it if needed. Foreign material inside the pump can also cause this, so disassemble and clean the pump. Other potential causes include a damaged impeller (replace it), worn motor bearings (replace them), or a suction lift that's too high (lower it, install a foot valve, and prime the pump).

    What to do if my Flint & Walling Water Pump has little or no discharge?
    • C
      Candace RodriguezNov 11, 2025
      If your Flint & Walling water pump has little to no discharge, there are several potential causes. First, ensure the pump casing is filled with water. Other possible causes include: the total head being too high (shorten suction lift or change head); suction lift being too high or long (lower suction lift, install foot valve and prime, or shorten the suction line); a plugged impeller (clean it); a hole or air leak in the suction line (repair or replace it, using pipe sealing compound instead of Teflon tape); or a foot valve that is too small (match the foot valve to the piping or install one size larger). Also check if the impeller is damaged (replace it), if the foot valve or suction line is not submerged deep enough in water (submerge lower in water), if there is insufficient inlet press...
