PVC pipes underneath the floor

[Wiliie Hugo]

Hi to you all, how do i get pipes from the DB to the end of the pipe( in powerskirting) open? Its not old pipes (6-10 months). The fishtape goes up to 75% into the pipe, but then got stuck. There was no previous wires in the pipe.

Hi

Have you tried from the other end - Does it get stuck at about the same place ? Assuming it is 20mm or 25mm

Do you have a wire wizard that you can pump air down the pipe and see if it will dislodge or at least get air out the other side - If you do not get air out then the chances are that a coupling came loose during the concrete pour

Other method is to stick a hosepipe on and try flush with water -

If there is a bit of cement in the pipe , leave pool acid in the pipe overnight and try flush the next morning , obviously acid comes with it's own set of problems

Thanks, i'll try to get a compressor and pump air through the pipes. I think it is small pieces of cement that got stuck
