When I open any faucet in my house: hot or cold water, in the bathroom, or in the kitchen, or in the laundry (basement), or even after flashing a toilet, my pipes start "singing". It started about a year ago and gradually is getting worse and worse. I was unable to determine the exact location of the source of this sound, but it's definitly someware under the floor of my bathrooms (they are located back-to-back in my rancho style house). What could be the cause of such a "music"? How can I fix the problem?
Thank you.
