I have a drain pipe that goes through my garden, and it's clogged. I've cleared the pipe from a manhole cover, but not 100 %. I also have a special type of water cable that is designed to clear blockages.
The problem is that when the cable stops after 10-15 meters, I don't know where.. I'd like to find out where the block is, so that I can dig down to the pipe and do some brute force.
How can I find the pipe, from under the ground? Use a key finder with high noise, that I can attach to the cable and put it in the pipe? Would this be loud enough so that I can hear it from 0.5-1 meter deep ground?
I appreciate all creative answers here!
