After I showered and shaved in our bathroom this morning, I heard an unusual, animal-like howl that repeated several times. After confirming that there was no dog or other animal making this sound outside the window, I discovered that I could control the sound by turning the sink faucet off and on. On closer inspection, I believe that that the source of the sound is inside the bathroom's outside wall (the exterior of the house) -- where the pipes run. (I now recall hearing similar sounds in the past, but perhaps not so loud.) What problem might I have with the pipes?
