Hi folks, I am getting to the end of my rope (literally) on this one! I am trying to help a friend with a stuck S.S. submersible in a 4 inch steel casing. Here are the numbers: Pump is down 61 feet with nylon pull rope and 1 inch pvc pipe which we know is somewhat brittle. It does have an arrestor. Well has been dormant for 2.5 years as the owner died. Pump has been down about 30 years. I made a 3-7/8 cutter and scraped the walls of the case down to 60 foot and then blew with 400 scfm to clean the well down to the pump (I have done this before on another well). From there we had 65 ft of 1/2 inch steel pipe and pounded on the pump until we mushroomed the pipe end. Nothing is moving! Any suggestions on the next step-bigger pipe or chemical?? If chemical, how much, what kind, and how to apply?? Should the case be empty of water when applying chemical or does it matter?? I dont think the water has any other issues other than high iron content.
