I have a plastic conduit about 6meter long and buried about 50mm down in a concrete floor. I have access to one end to thread a wire through, the other end is somewhere on the opposite side of the room. Can anyone suggest how I can find the postion of the other end?
Thanks, Ken
Why cant you work out where the other end is?
A bit more info required.
If the other end is buried push a snake or stiff wire into the conduit till it hits the end then lay the snake on the concrete to give the end position. Only works if there are no bends of course.
That will give me the distance from the open end but not the lateral position. If I poked in a return wire and ran a low voltage current through the wire, is there an instrument that can pick up the charged wire beneath. I have noticed Telecom guys dig up cables with some accuracy but have not seen how they locate the cables.
Thanks, Ken
The instrument you need is a cable locator but they start at around $1000 for a half decent one. You might be able to hire one for a couple of hours.
If you push the snake or the wire in and push it backwards and forwards so it hits the end of the conduit and makes a noise and get someone else to listen it should give you an approx location.
Or fill it with water and devine it.
Nice tip Barry. :UQuote:

is there reo in the concrete, if not you may be able to use a metal detector to sense the copper.
I've got a stud detector GMC which also detects "live" wires and nails...Quote:

1. Blow smoke in and look for where it comes out.
2. Blow compressed air in and listen for it coming out.
3. as 2 but put some flour in the pipe first.
Above assumes the end is not buried.
1. If end is buried then fill with water and look for a wet spot.
2. Slide an stick of jelly with an electric det right to the end. Apply power and the end is (was) in the resultant hole. :o :no:
