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.

       Is it clockwork?

       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 did find.

       I downloaded a few studfinder apps for the android phone. Some nearly work, which I found surprising. Too many false positives and also false negatives.

       // studfinder apps for the android phone. // That is intriguing. How are they meant to work?
MaxwellBuchanan, Mar 22 2017
  

       Well, a proper handheld dedicated device uses a combination of magnetic detection / metal detection, and also capacitance change (to detect a wooden stud behind plasterboard, even though there's no metal around). The apps can't do the capacitance gradient step detection, they just rely on the magnetometer in the phone spotting things like cables, and the clout nails that hold the plasterboard to the studwork.

       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?
