    Cable stuck - Chico

    Have a seal off at a waste water lift station, for a submersible level transmitter. At the seal off Contractor used Chico but no cotton. Dug the Chico out of the sealoff, Chico ran down the conduit and now the cable is stuck....not possible to access the conduit elsewhere.
    Suggestions? Long drill bit, solvent, mice?

    You could try pouring "Coca Cola" down the conduit and let it sit awhile.
    Or "Polywater" I've heard will sometimes work.
    If you aim at nothing, you will hit it every time!

    polywater makes a stuck wire lube that might get it.
    not regular pulling lube, for unsticking glued in conductors
    pulled with yellow 77, 88 years ago.

    a lot depends on if he filled up the 90 at the bottom.
    i've unblocked pipes filled with slurry with muriatic acid,
    a piece of fish tape chucked in a drill, and rubber gloves.
    it is not much fun.

    how big a pipe, and what size wire?

    Mayhaps you can blow compressed air into the other end and manipulate the wires at the problem end.

    I’ve only witnessed, but muriatic acid has worked in my experience - it does take a while and patience, but that’s the name of the game no matter what technique you use.

    just put a bag, full of holes of course, but filled with cotton balls, at the one end... air flows through, acid soaked by the balls... a few pieces of wire holding it in place or zip tie.. not as messy as it could be...
