DIY Simple water pump from Refrigerator Compressor

[Frank S]

While I don't know how long the compressor will last pumping air continuously. I do know of several wells in my area that are considered too low producing to even install a wind mill on them.
Some will pump dry if trying to pull more than 1 gallon per minute from them. Your pump is doing about half that rate so the wells should be able to readily recover while water was being removed.
the next problem would be the remote locations of these wells means there is no electricity but a couple large PV panels an inverter and a small bank of batteries should solve that as well. leaving only a way to retain the column of water when the pump is off. adding a T in the pipe then running the air line through the T and seal it off then add a foot valve below the T should help solve that problem.
In the end this cold be an off grid homesteaders viable option to pull water from the ground.
Thanks I know where there is an old well on my property that someday I might try just that.
