It's not that simple!
The well point you are talking about is a well screen and not a well point. First you would need to wash a 4" hole in the ground by making a wash down bit from a 3" PVC coupling. You would need to cut saw type teeth on the bottom of the coupling and adapr the other end to a 5' section of pvc pipe. You would need to dig 2 mud pits, 1 about 2' by 3' near where you want the well, then dig a second pit 2' by 2' about 12" from the first pit. These pits should be about 18" to 2' deep. Then cut a trench wrom the proposed well to the first pit and cut a wide shallow trench between the two pits. Now you will need a contractors trash pump with a suction hose and screen. You will place the suction hose in the smallest pit and the outlet hose from the pump will need to be connected to the top of the 1-1/4" by 5' pvc wash pipe. Once this is done you will need to purchase some drilling mud (powder), about 50 lbs. from a drilling contractor or a well supply house. Mix the powder slowly with fresh water in the mud pits until you have a consistancy equal to a malted milk drink.
Now you're ready to start drilling (washing) a hole in the ground. Start the pump and turn the 1-1/4" pvc, with the bit on the end, back and forth about 1/4 turn and let the pipe wash a hole in the ground. When that 5' is down, add another and another until you reach a good clean water sand the returns to the top of the hole and into the first pit. Hopefully this will be at least 40' total but 18' to 40' may be OK.
Keep in mind the above instructions is for sand only. If there is any clay or rock, the above may not work for you!
Once you have the hole to the desired depth, remove the 1-1/4" pvc quickly and replace with 1-1/4" pvc with the well screen on the bottom end (cap the end of the well screen). Once the well screen is in the washed hole to the depth you desire, you can pump clear water through the 1-1/4" pvc and out through the well screen until a thin almost clear water returns around the pvc at the top. Immediately remove the hose from the 1-1/4" pvc and pour at least one bucket of clean sand around the pvc pipe. Be sure to allow water to flow out of the 1-1/4" pvc, around the pipe and back down the hole. Once this is done you can connect a pitcher pump to the 1-1/4" pipe and pump it until it pumps clear water.
Next connect a shallow well jet pump (not a lawn sprinkler pump)to the well, prime it and your done.
I recommend installing a small 1 to 5 gallon pressure tank on top of the pump. This way it will be automatic and stay primed.
Keep in mind that the state has well regulations, requirements and may require a well permit before installing your well.
You must follow the above steps to a "T" otherwise you will encounter serious problems.
Remember, I said it isn't that simple and it isn't easy! Even experienced drillers have problems in sand.
Good Luck and good drilling!
