Supplying Water to your Cabin with a Driven Well
There are two different types of point. The regular point is used in sandy soils. The washer well point is used in gravel. This type has drilled and countersunk holes fitted with brass wire gauze. Drive pipe usually comes in 5-foot lengths. It should be galvanized so that it won't rust and should have externally threaded ends to receive the couplings as sections are added.
To start work on a well of this type, spade out a shallow hole in the ground. Next, you will want to make a drive assembly unit. This assembly consists of a nipple, coupling, and a malleable iron drive cap. Apply pipe joint compound to the outer threads at the top of the well point and screw on the drive assembly.
Tighten the whole business with a pipe wrench. You are now ready to start driving the point into the earth. When you have driven the first length about three-quarters of its length into the ground, remove the drive cap and nipple. Leave the coupling attached so that you can add a length of pipe. Apply joint compound to the threads again and connect the pipe length to the well point.
You'll find that each blow from your maul tends to loosen the joints. Tell Junior to give the pipe a twist after each blow. When it gets too difficult to drive the assembly any more--use a tripod over the well. Suspend a heavy block from the apex and use a rope and pulley to drop the block on the top of the assembly.
Sometimes water appears in the pipe, but more often you will have to lift the pipe out to see. When the point has been driven far enough, lower the suction pipe and foot valve into the well. Hook up a pump and test the flow of water. You may find that the flow of water is small at first.
The point is probably clogged. It will probably clear itself as you continue pumping. After you have finished driving the well, slip a reducer fitting over the suction pipe and screw this to the top of the drive pipe assembly to cover the gap. If the small opening of the reducer will not fit over the suction pipe, file it.
Any of the pumps mentioned before will be satisfactory for this installation. In the accompanying illustrations I have shown the important details of such a system. A jet or reciprocating pump is used.
This is one type of well that you shouldn't try to do yourself. If water is too deep to be reached by any other method, or if rock lies between the surface and water level, you may have to use a drilled well. But this is a job for a professional. Find out from your neighbors who has a good reputation--then hire him.

"you have not put in many drive-points, I can tell. you dont put in a foot valve, you put a 1 1/4 check valve at the top and reduce it there. you dont pull out the pipe to see if you have water. pump it with a hand pump or pump air down it with a compressor and see how much water is comming out. I could go on and on, I put these things in for a living."
