Hot water pipes are the only plumbing pipes that will make a squeaking sound. The squeaking sound is due to the heat of the water causing the pipe to expand as the water passes through it. When the pipe expands, the expansion of the pipe causes it to rub against the anchoring straps, creating the squeaking sound.
