I currently have a loud and persistent vibration in my house that apparently was caused by my water pipe (I want done to basement and can feel with my hand that the vibration is mainly in my cold wafer pipe). The vibration noise will immediately stop if I turn ON any faucet in the house, but will come back with 2-3 seconds after the water is turned off, and it also slowly builds up even if the water were kept running for a while (like a minute or so).

Similar, but short lived (5 to 15 seconds a time) vibration started few weeks ago and it has become frequent. Now the vibration doses not seem to stop. Help!
