I know this is slightly off topic, but since I am intending to run
some RF cable in the conduit, and since there are a lot of intelligent

Last year at the beginning of construction of a new house I buried
about 50 feet of 3/4" Sched. 40 PVD between the house and a location on
the property perimeter. Now that I am ready to use it, I can not
locate the perimeter end.... it is somewhere in about a 10' area, and the
end curves up to probably about a foot underground.

The ground is nearly pure sand, and is well landscaped now to the
point that I do not want to randomly dig it up.

The end terminated in an elbow curving up and is well duct taped
shut.

Can anyone suggest a method or equipment I might use to locate that
far end?

Tnx.

I have some pipe that I had run for an outdoor spigot that I never
finished installing. To test a method of finding it I shot some air
into it the other end was pretty easy to find by listening. I could
hear the rush of air and a lot of gurgling. My dog actually found it
in the roses bushes before I did.

Hi Jimmie

That "air" idea wont work, Jeff told me so

It can work, because what you are trying to do is not to move a lot
of air and sand, but try to make some noise. And you don't have to move
a whole lot of sand to do that. As long as the pipes stay together, some
air will make it out of the open end and make some noise.
