Why do water pipes thud?
If your pipes make a thud when you turn off, hot or cold water then you might have a water hammer problem. This is the most common pipe noise which can be caused by a pressure surge or wave caused when water is forced to stop or change direction suddenly. When you shut the water off the thud should be gone.
