Installing the pump is a tough job, assuming you are referring to a submersible pump. The problem comes from the fact that well pipe comes in twenty foot sections, so you have to stop every twenty feet, secure the pipe already in the well, (hope to goodness that it doesn't come loose and drop down into the well!), add another twenty feet, lower it down, secure the pipe again... well, you get the picture. Once the pump is installed, the rest is farily simple, though time consuming. On top of everything else, you have no assurance the well is still useable. Have you determined where the water table is with it? Also, are you comfortable working with the electrical side of things?

This will be a shallow well install. Water well is about 20 feet I am comfortable on the electrical side more so than the plumbing side.

Well, I do not claim to be a well expert but I have worked on my own a good bit and seen it worked on as well. At only twenty feet, you can use a jet pump if you'd prefer. This site has a good discussion (and diagrams) of jet and submersible pumps.

Both systems work in the same way once the water gets to the surface. As the pressure tank fills, air in the top of the tank is compressed which produces pressure on the water. Once the pressure rises to a certain level, say 50 pounds, the switch senses this and will cut the pump off. As water is used, the pressure drops until, let's say at 30 pounds, the pump is switched back on.

Most diaphragm tanks have a single opening in the bottom of the tank. You will need a brass "T" fitting which will have the water entering from the pump at one end and exiting to your house at the other end. The switch will also connect at one end or the other of this fitting.

I'll answer any questions I can. If I can't, I will be honest and just tell that to you. There are others on this site who are knowledgeable.
