What is causing a vibration from inside the wall?

Question

There is a vibration coming from inside the wall in my bathroom. It makes a thumping noise. It's not constant. It comes and goes.

When I put my finger on the wall where it is coming from and put some pressure on it, it stops. What is causing this?

Answer 1

Possibly air in the pipes.

Answer 2

Definitely water pipes, what you can do is make a small hole and spray a foam sealer into it.  This should quiet the noise without tearing apart the whole wall.  Make sure you locate the noisy pipe first!

Answer 3

Answer 4

Answer 5

its called water hammering and it is usually do to a na loose pipe support on your water line.. you can get water hammers they are like shock absorbers. when you shutoff the water at a fixture the pressure of the water suddenly stopping causes the pipe to vibrate.  water hammers absorbs the shock and allows the water to expand causing no vibration.

Answer 6

My guess a lose water pipe vibrating .
