Ejector Jet stuck in well

Hello all, First time poster. My problem: We have an old farmhouse with a 3 in well, about 70ft. deep Water has been good quality and good supply until recently. The house stood empty for a little over a year and well was un-used during that time. Renovating the house and when we tried to pump water it came extremely slow..... Did pump up to pressure after a long while of running...but as soon as you draw out the supply from the pressure tank it is a slow draw again. It is a jet pump system with a 3/4" and a 1" line going down the well. We put a new pump on and no change. Thinking that either a problem with the foot valve or the screen had gotten plugged over. The lines are the black plastic with hose barb ends and hose clamps. Tried to pull them out and the ejector is stuck... have a come along for a good solid pull, but know that can only pull so hard or will tear the line loose...:( Have lowered 1" shaft on a good rope down alongside the pipes and have banged on the jet??? quite a lot, with absolutely no results... After 4 or 5 days of periodically hammering on this thing' I am certain it will not come out. In my mind I have came up with the idea of welding pieces of sawblade to the bottom of a shaft and lowering it down to just above the ejector and slowly turning it with a drill with the hopes that it will knick/cut the lines enough at that depth that the hoses rip loose at the depth of the jet..... I know....that sound crazy..... but this area is mostly sulphur water and if we drill a knew well, we will likely get that kind of water. :( So my question is: Question#1. does anyone manufacture a 2 line jet for a 3" well anymore??? I have searched the web and made a number of phone calls, and have came up empty handed.. I have located a 1 line system that uses a leather seal on the ejector. Question #2 If by some miracle I get those lines cut off at the old ejector, will I have a water supply that would still be able to work up past the old ejector in the well? With a 2 line system there should be no leather seal to block off the water supply...right? Question #3 Once I get those lines cut off, how could I pump water up out of the well to determine the supply flow before I make the investment in this 1 line jet system. It was quoted to me at $371 not including the piping. I appologize for such a lengthy post, But I am desperate to save this well!!! Thanks for all replies!!! Rick
