Ever tried to follow a water pipe, only for it to disappear behind a panel or under a floor into a nest of pipes? Unless you pull up loads of nails, floorboards, walls, etc, it's impossible to work out where it goes and where it comes out.
There are tools that can find pipes in walls and in the
ground, but not that can follow a single pipe as it passes around and behind other pipes, or through an inaccessible area. But this device will clip onto a pipe as it disappears into a hole and send vibrations through it (frequency to be determined by experiment). You will then be able to find where the pipe emerges by finding which pipe is vibrating, either by touch or a sensor. Gripping the pipe with your hand should damp the vibrations, allowing you to isolate the section you're interested in.
The result will be an inexpensive device enabling you to recognise a section of piping and mentally connect one end with another. Ideal if you're not sure what a pipe is connected to, or where the valve to close it off is; and particularly useful where you can see a few pipes disappearing into a box and more pipes coming out the other side, but you can't match them up.

||Just get someone to bang it with a hammer like everyone else does.
||This is a good idea, especially because of the images it conjures up imagining what you were up to when you thought of it.
||The last time I followed a water pipe I got pretty wasted.
||Something you can do to trace hollow PVC wiring conduit: connect one of those small 9V piezo beepers to a 9V battery via a switch. Stick the
beeper into one end of the conduit. Hunt around the building or whatever for the sound - which is where the other end of the conduit ends. It works very well. The switch is so the beeper doesn't drive you mad at other times.
||Anyone else remember the idea where each faucet,
shower, washing machine, etc. in the house would be
given a fluttering valve thing inside its connection to
the water supply pipe, and these would all be made
such that they'd flutter at different frequencies,
powered by the water flowing past? The claim was
that this would help locate dripping faucets and other
leaks. A criticism I remember was that scale would
build up on it and prevent vibration. Another
problem I can think of, though I don't remember if it
was brought up then or not, is that the slow flow of a
dripping faucet would produce a different sound than
the fast flow of it being turned on, and different rates
of dripping would probably produce different sounds
too. Anyway, I tried both the built-in search here and
Google with many different terms and couldn't find it.
I wanted to find it so I could post [links] on it, which
I'm posting here because it's the most relevant thing I
||// studfinder apps for the android phone. // That is intriguing. How are they meant to work?
||Add a very small whale to the pipe, then just follow the call.
||What's the diff between this and tapping on the pipe with a wrench?
