Does anybody know of a way to get a pump out of my well that fell to the bottom and is sitting on top of the screen - the well is 80' to 100' - If I can get the pump out then I will not need to have a new well drilled. We have put in another pump and that is working just fine but I can not run the water for more than 30 minutes at a time because the water can not get by the old pump that fast. It is a 4" well.
