Well pumps come in two ways. One model for shallow wells and another for deep wells. If your guy put the wrong one in he shouldn`t charge you for replacing it !ours is down at 430'. I would probably have a bit of a problem getting pulled up. but now I don't seem to have the pressure we used to.
gonna have to call him on Mon and see what the deal might be. I really hope it isn't a pump with the wrong volume.
