Maybe I just never heard it until I go to bed. My wife and I just bought a house and in the basement there is a noise that seems to be one from the heat runs, and two from the pipes. Now the noise from the heat runs seems to sound like a hammer tapping in the supply. The noise in the pipes sounds like a dripping but loud threw out the night. Like I said we only hear it when we want to go to bed but the noise has keeps us up. Our bedroom is above where the unfinished side of the basement. We have hardwood floors in the house and the noise goes right threw them to where the noise is heard in our bedroom. If there is anything please let me know any info. Will be much appreciated. I need to sleep again.

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
