Thats got to be it! I think thats how this will have to loosen up. I'm glad I didn't just try to pry it out!

Now let me ask this: is this a good sign - as the pump may not be that far down? Or is it still possible that it is over 100' down there? Would any of you hang a pump by that adapter and just leave the pull pipe to hold the weight? There is no safety cable on it...
