I just started messing with well in back corner of house... i will give you the run down.. The house was built in the 50s...
has a vertical pump on top of well with about 70ft of pvc looking pipe going down...( there are two pipes) .. Both pips meet at a filter of some sort...
The motor is a Universal 1/2 model#112... (pretty old looking)
had a black and white wire from the motor that i connected to a plug.. . the motor hums but does nothing else..
Looks like the well is about 80feet or so down with water at 15feet from the top.. there is also a sleeve on the inside of the well.. and its looks like its about 5 or 6 inches wide...

New pump-- what hp and stype pump should i get..
Old pump.... can the old pumps just freeze up , then be broken free...?
Is there a chance this well could be ok to drink ? i am just not familiar with wells and the depth it takes for drinking?

I am really just looking for some irragation on my little yard..

Sorry so long...

 

There are several things that could cause the pump to just hum.
Most pump motors have a start capacitor that helps the motor start. If this capacitor is bad, the motor can't start. An electrician can help you with this.
Other causes include bad bearings in the motor, which usually isn't worth messing with, or the pump components are damaged and have the pump/motor locked up.
The thing that the two pipes are hooked to is an ejector. This device is necessary for a deep well pump system to work. If you install a new pump, you'll need to replace the ejector as well.
The size of the new pump will depend on what you want to do with the water, and how much water you need. Of course, you need to understand that most wells have limitations on well yield.

thanks for the help..
were do you find such info as well yield and such.. is it a formula?
I guess i am really just trying to get it going the easiest way to water my yard.. my lot is only 1/4 acre and a house takes up space on it.. I have been told i can get a small pump for a 100 bucks or so.. ??
