Hi,
Can anyone tell me why we would hear a dripping sound when we initially turn on the shower, and then it goes away after a couple of minutes while the shower keeps running? Our shower is on the top floor. No wetness noted on the ceiling below, although it had leaked at one time. It sounds like a "hollow" drip sound, if that makes any sense?

:confused:

Ahhhh! The dreaded mystery noise when you're alone and naked in the shower. Isn't it more of a clicking noise? Let me tell you what I think it is. Knocking, popping, creaking and crackling pipes are a common complaint, especially in colder weather. I can tell you what's happening and take the mystery out of it but you're not going to like the repair. When a draw is made on a hot water line the line expands against a pipe strap next to a stud and when you drain hot water from your tub or shower it goes into a chase that is a little cooler then room temperature. The heat expands the pipe causing it to rub against the stud to which it is pipe strapped. This is the sound you hear. As it cools it contracts and the noise is heard again. To repair it you must tear open the walls and locate the pipe strap that's causing the problem and shim it tight. Most people when they learn what causes it just elect to live with it. Regards, Tom
