    Hi

    We have Dug a Boring hole uptill 500 ft below, we managed to release the submersible pump till 240 ft, unfortunately the Iron pipe broke and the Pump went rushing till the end.

    We would like to extract the submersible pump along with 20 no's * 20 ft pipe with the PUMP.

    Can you pls let us know different process or way to sucessfully extract the pump.

    Thanks

    Navin

    Where did the pipe break? Do you have a coupling on top or did the coupling break off which would leave only slick pipe to grab on to?

    In the "old days" they used a drive shaft from a model A which was hollow and tapered. They dropped it down the well and it slid over the pipe and usually "jammed" it so the pump came out when they retrieved it.

    i've fished out alot of broke pipes with a taper tap and/or an "overshot" inside tapered fishing tool... though i've never done anything close to WWP at pullin 300' out of a 1200' hole.. kudos to you waterwellproducts, i bet that was a PITA to say the least.

    I have fished a lot of things, and it is always better to know what is sticking up at you. It is much easier to grab a couling than slick pipe. With a couling sticking up, I use to make an overshot out of pipe that would fit over the drop pipe. Then put two or three flat pieces of steel about 2' long and welded at the bottom, inside the overshot. When you slide this over a couling the top of the flat steel catches the coupling and out it comes. Sounds easy but sometimes its not.

    Hi

    Yes the coupling broke & the pipe is only to grab on.

    We tried traditional way by dropping the Iron Hook with the rope tied, But due to weight the pump and Pipe the rope broke half way and again went down.

    Sounds like your situation went from bad to worse. Not only do you now have a bunch of pipe and a pump in the hole but now there is a length of rope and an iron hook down the hole as well. Unfortunately the rope and hook will probably impede your efforts.

    What size is the casing and what size is the pump?
