SUBMERSIBLE WATER WELL PUMP SAMPLE SYSTEM INSTALLATION

Dean Bennett Supply Company in Denver Colorado has been supplying pumps and water system components to the water well industry since 1965. Whatever the water well system requirement, we can help you to do it yourself. We sell the submersible water well pump, the wire for the electrical connection, the pipe, the water pressure tanks, and the controls for your water supply system. Call us for a free catalog of pump and well supplies at 800-621-4291. This sample system is for a low production water well that is real deep.

We are assuming a deep well with low production. A 6" well with 4" ID PVC liner drilled 400' deep and producing 4.5 gallons per minute. The static water level where the water seeks its level in the well is 300' from the surface. There is no further rise after getting to the top of the well.

We are going to use 1" Schedule 80 PVC drop pipe, with 1" brass couplings to set the pump. We will set this pump at 380 feet below our pitless adapter for underground discharge of the water to your home.

You will need to install a pitless adapter into your steel well casing below your frost line, to distribute the water from the well to your home. I recommend the B10-X 1" pitless adapter for this installation. This is done by cutting a hole through the well casing with a hole saw to install the pitless adapter through. Installation is a little tricky since you must not drop the unit in the well. Most people lower the piece that goes through the well casing wall down on a wire that is stiff enough to control the pitless unit, and slide it through the well casing hole, but still soft enough to be able to bend easily. By routing the wire through the bottom opening of the pitless adapter piece, and out the discharge side of the unit, you can bend the end over the outside of the unit to prevent it from coming undone. Lower it down and through the hole in the casing, and while holding it from the top, have someone grab the piece coming through the hole to hold it. Bend the wire down slightly to allow you to slip the rubber washer over the piece sticking out of hole. Place the brass curved piece over the male end sticking out, and then while holding the piece so it can't slip back into the well, screw on the nut that secures it in place. This now will leave a receiver on the inside of the well which will accept the piece that comes up from your submersible pump.	The B10-X pitless adapter cost you $ 73.75
For this instance, I recommend a Flint & Walling model 4F05S07-301 submersible pump. It is a 4" pump rated at 5 gallons per minute, and powered by a Franklin Electric 3/4 hp 230 volt 3 wire with ground submersible motor. This motor requires a pump control box between your house power and the motor, to properly start and protect the motor of the submersible pump, which comes with the pump. This model F&W submersible pump will pump 5.3 gallons per minute at 40 psi discharge pressure at the 300' static water level. Down at the 380' level where we set the pump, it will still pump 3.5 gallons per minute at 40 psi. This should prevent you from over pumping the well since the 3.5 gpm is less than the 4.5 gpm the well produces. If you have concerns about over pumping the well, we have units that can protect against running your pump dry. Call us for details on well protection for low production wells, at 800-621-4291.	Your cost for the 4F05S07-301 including the control box is $ 728.00
You will need a 1 1/4" x 1" brass hex bushing for in the top of the pump to reduce it down to 1" pipe size for your pump pipe.	Cost is $ 5.90
You will want safety rope for connecting between the pump and the top of the well.	We sell 1/4" polypropylene safety rope in 500' rolls for $ 25.50
In the 1" pipe coming up to the pitless adapter, you will need 3 check valves. One check valve is placed 1 piece of pipe above the pump, then one every 120' until you get to the top.	1" brass check valves cost you $ 23.60 for a total for 3 of $ 70.80
You will want to install a deluxe torque arrestor on the pipe just above the pump. This is a buffer that prevents your pump from slamming against the side of your well casing every time it starts. Clamp the bottom of the torque arrestor onto the pipe just above the pump. Slide the top of the torque arrestor down to expand the unit to the size of your casing, and clamp the top clamp onto the pipe.	Your cost for the Deluxe Torque Arrestor is $ 8.95
You will need about 400' of pump wire to come up from the submersible pump motor lead to the surface of the well. Lets assume that your house power is about 85' from the well. You could probably get by with 12-3 with ground pump wire, but I will recommend that you move up to 10-3 with ground pump wire, since the total distance from pump to power should only be 480' for 12-3 with ground. You are just over that and at best, at the limit. 400' of 10-3 w/ground is so close to a full 500' reel that it is more economical to buy the full reel than to have it cut to length.	Your cost for the 500' reel of 10-3 w/ground pump wire is $ 705.00
From the top of the well to the house power, you will need UF direct burial wire that can be buried in the ditch alongside your water distribution pipe. We sell cut lengths in 10-3 w/ground UF burial cable for $ 3.10 per foot. I recommend that you buy 100' of the UF wire to be sure you do not come up short.	Your cost for the100' cut length of 10-3 w/ground UF direct burial wire is $ 255.00
You will need a 4 wire heat shrink splice kit to connect the submersible pump motor lead to the submersible pump wire. The kit consist of 4 stakon connectors and 4 heat shrink tubes to protect against the water. You will slide a tube over each wire. Strip off the wire insulation to expose the wire end and crimp a stakon onto the end of the motor lead wires. Next you will connect the stakon to the matching color coded wires from the submersible pump wire coming down from the surface of the well, and crimp them to the motor leads. Slide the heat shrink tubing over the splice and heat it with a lighter to melt the tubing down over the stakon. The tubing will shrink down to where you can see the stakon through the tube and the sealant will ooze out the ends of the tube, all around the ends. When the sealant has oozed out sufficiently, the connection will be water tight.	The heat shrink splice kit cost you $ 5.75
At the top of the well, you will use a pitless well cap. This covers the well top to prevent things from falling into the well. It has an area for routing your submersible pump wire out into a consuit. The LX6-1 pitless well cap has a 1" conduit connection female thread.	The LX6-1 pitless well cap will cost you $ 43.75
You will also need a bell splice box where you will splice the submersible pump wire to the UF direct burial wire that will be going underground from the well to the house power.	Your cost for a 4" x 4" x 2" bell splice box with lid is $ 26.00
In the bell splice box, you will need 4 RED wire nuts which are for splicing together the #10 wires.	They will cost you $ .24@ for a total of $ .96 for all 4.
From the outside of the pitless adapter, where it sticks through the steel well casing, you will need 1" water distribution pipe for carrying the water from the well to the house. We recommend a 1" x 100' roll of 100 psi poly Pure-Core Blue 100 psi poly pipe for water distribution to the house.	This cost you $ 63.00 for the 100' roll.
You will also need 2 - 1" brass insert male adapters to give you male pipe threads on the ends of the poly pipe.	They cost you $ 8.10@ for a total of $ 16.20 for the 2 insert male adapters.
You will also need 4 H16SS 1" stainless steel clamps to secure the insert male adapters into the pipe.	The clamps cost you $ .81@ for a total of $ 3.24 for 4 clamps.
Finally we have water to the house from the well. In the house, we will need a bladder type pressure tank. Selection of the pressure tank is important. It will supply your level pressure for the household demands. Our well pump put out about 5.3 gallons per minute. The smallest tank you should use is a Air-E-Tainer #AT-66 which will give you a draw down, of usable water from the tank before the pump comes on, of about 6.2 gallons.	The AT-66 tank cost you $ 188.00
You will also need a tank fitting kit which has the long tank cross, the pressure switch and a 4" brass nipple to elevate the switch on the tee, a 100 psi pressure gauge, a 1/2" brass boiler drain, and a 1" brass check valve to prevent water from going back toward the well. We also recommend the add on of a 100 psi pressure relief valve, since the tanks are rated for 100 psi maximum pressure.	Your cost of the 1" deluxe fitting kit with the 100 psi pressure relief is $ 84.60
We just described the minimum size water pressure tank to use with your system. Going larger only makes your well system perform better. I would recommend an AT-144 which gives you a draw down of usable water of 13.6 gallons at 30-50 pressure switch setting.	The AT-144 cost you $ 438.00 and the 1 1/4" deluxe fitting kit with 100 psi pressure relief will cost you $ 117.55
Using a 30-50 pressure switch setting will make your system provide a nice pressure for the water system use. When setting up your pressure tank, before putting water into the tank, adjust the pressure in the top of the tank to 28 psi, or 2 lbs below the cut in pressure of the pressure switch.
