  • 8IN sewer line testing

    Question for you guys that install the big stuff.....I got a call today that a company testing 8in sanitary sewer lines got their mandrill stuck in the line...It is a metal one...Ive seen people use string and plastic bottle to check the lines but never a metal one...Fortunately it is stuck 15 Ft away from the discharge end of the manhole.... Im thinking of using a ton of dishsoap and a sectional to try and dislodge the mandrill...The pipe is PVC

    Anyone ever run into this problem??? I would love to hear some suggestions, or success stories


    Thanks,
    Greg

    greg, can you run the camera from the manhole up to the 15' mark and see the problem? it could be a damaged pipe or joint?

    take pictures of your find. it could be worth a trip to ridgid and $2500.

      Yes i can see it where it is stuck...It is not a main that is in service right now....they were testing to make sure the pipe was round i guess...Anyway it looks like it got stuck on nothing, so im guessing the pipe is not round right there...

        I would think you'd be fine using 1.25 sectional with retrieval tool. Once you have it hooked do not turn any more just pull. Obviously you want to back it out. Is it the last 15' of the test or the first 15'?


        Why are they not just digging it up. Running a mandrill is part of the inspection process to test for deflection. If the mandrill wont pass freely the the pipe is deflected/squated too much to pass inspection. No way the inspector is going to pass it unless of course he getting a thick envelope.
        At 15 from a SMH my guess is someone mess up their grades and tried to make up for it in one section of pipe. Or they made a clay check dam to stop the water and never removed the clay when they back filled.

            The idea of running the mandrel is to check for out of round pipe. When it gets stuck you are suppose to dig it up and fix it.

                The will/should dig it up, its pretty obvious to me that the squished it a little and its not round anymore
