To select your water well pump system, you will need the following information.

Depth of your well____________ and static water level, which is the distance from the top of the well down to the water is ___________? How many gallons your well produces per minute ____________? At the top of the well, do we have to pump water up hill from the well to where we are going, and if so, how many feet straight up elevation _____________? How far away is the breaker panel where public service provides you your power ____________? What size well casing is at the top of the well, and is it steel or PVC ___________________? How far are you pumping the water away from the well _____________? What PSI water pressure is needed at the end of the line? What size and type of water pipe are you going to pump through, from the well to the location of the pressure tank ____________? Are you planning on doing lawn irrigation or other types of water usage, other than just household use?

With the above information, you can select a water well pump that is sized right for your well, and select the water pressure tank and accessories needed to complete your well system.

4 inch Flint & Walling submersible water well pumps are available in 5 gpm through 85 gpm pump series. Most people need a pump with 19 gpm or less pumping capacity, based on their water well capabilities, and their water requirements.

Flint and Walling also offers irrigation submersible pumps in 6" size. 6" pumps are available in 80 gpm through 325 gpm series pumps.

All of Flint & Walling's water well submersible pumps are powered by Franklin Electric's motors and controls.

Call us for assistance in selecting the water well submersible pump to fill your pumping requirements.

F&W 4" Submersible Water Well Pumps

Twisted water well pump wire connects your pump to power.
Submersible pump wire is designed for use in the water. The wire coating is suitable to protect the wire from water, and we offer special heat shrink splice kits that have stakon connectors to connect the wires, and heat shrink tube to seal the splice to keep it water tight.

Submersible Pump Wire


The torque arrestor is used to prevent motor start up torque from thrusting the pump against the side of the well casing. Think of it as a shock absorber for your well system.

Torque Arrestor for Water Well Pump


You should use a check valve in the well at 1 piece of pipe, or 20' above the pump, and then another check valve every 120' in the well. This keeps the water pipe full of water, and prevents up thrust force against your motor bearings and pump bearings.

Brass Check Valves for in the well installation

The pitless adapter is used to make an underground discharge connection from the pipe coming up from the pump, to the pipe going under your frost level to the house. This helps keep your water line from freezing during winter, and you do not have exposed pipe coming out of the well above ground. One half of the pitless adapter installs into your steel pipe casing to make connection to the underground pipe. The other half will connect to your pump discharge pipe, and then you will lower it into the piece installed in the casing side to make a water tight underground connection.

The pitless well cap goes over the top of your steel or PVC casing to make a protective cover, and has a provision to bring your pump wire out of the top of the well, so you can splice it in a wire splice box on the well top.

Use a BB44 4"w x 4"h x 2" thick splice box with a gasketed lid. The splice box comes with 5 openings for 1" conduit, and plugs for 3 of the openings. Use one opening for your pump wire coming out of the well, and the other opening for the buried wire coming from your house power supply.

The bell box is a heavy aluminum 4" x 4" x 2" deep wire splice box for at the top of the well, which gives a great place to splice your underground wire to the pump wire.

The bell box comes with 5 - 1" conduit connections, and 3 plugs for the ones you don't need.

Bring your pump wire down from the well cap into the splice box and then bring your underground buried wire into the splice box, and connect them together with wire nuts. There is a gasketed solid lid to keep your wiring dry inside.

When you need to service your pump, the bell box gives you a great place to separate the power wire from the pump wire.

The Franklin Electric control box that powers your submersible pump, should be in the house, where it will be protected from the elements.

The control box has a capacitor and a relay in it. These control the start up and run of your pump motor.

Airetainer bladder type pressure tanks are designed to give you worry free stable pressure for your home. Tanks work with a 20 psi pressure variance between where it calls for the pump to turn on and where it turns off.

Select your pressure tank based on the amount of gallons per minute your pump produces. If your pump is pumping 12 gpm, you will need to select a pressure tank that gives a minimum of 12 gpm draw down. This is the amount of water that can be taken from the tank, before the pump turns on, and assures that the tank  has at least 1 minute of run time, when it turns on.

Water Well System Pressure Tanks


The tank fittings kit consist of a long brass tank cross, with openings for all your components to be installed. A 1/4" x 4" Brass Nipple is included to install the pressure switch onto. A 100 psi pressure gauge tells you the pressure available. A boiler drain with hose thread connection is great for times you need to drain your tank. A Check valve is installed on the incoming line from your well, to prevent pressure back toward the well. We recommend a 100 psi pressure relief on the fitting kit to protect your pressure tank maximum pressure rating.

Water Pressure Tank Fitting Kits


If you have a low producing well, where you could run it dry, you can protect your pump with a PumpTec. The PumpTec is a controller that senses change in motor amperage. When you run out of water, the motor spins faster, changing the amperage draw. The control turns off the power to the pump for a set time.

PumpTec Pump Protection


BW Electrode System is another great way to protect you well pump. The BW system uses 3 electrodes in the well. 1 below the pump, 1 just above the pump which will turn it off when the water level drops, and 1 up at a level where the water has to recover to, so the control will reset and allow power to the pump.
