Is there a detector of plastic pipe?

Question

I know metal detectors for walls, but in my house there are places where it has a plastic pipe. I wonder if there is a good detector to buy.

Answer 1

Typically in the ground they use expensive sensors and ground-penetrating radar to accomplish this. If you can find a stud detector that can detect water in the pipes (you need something to conduct), then you should be in business.

This company makes a plastic pipe detector. And so does this company. I imagine it uses radar to do it or sound waves.
