I had a similar situation happened to me. I was having a bad pump being pulled up, when the plastic 1-¼” pipe busted, and the pipe and the pump fell back down into the well. I was able to hook onto the truck rope that was teid onto the pump and we pulled up the pipe and the pump that way. The pump guy never told me that there was a chance that it would get hooked up, so maybe our situations are not the same, but everything worked out okay.
Good luck, Mike
