Creaking or cracking sounds are usually caused by the expansion and contraction of the water pipe itself. When hot water runs through a pipe, it heats the pipe, causing it to expand a bit . Once the water stops flowing, the pipe cools and the metal contracts, resulting in the creaking or cracking sound. The easiest way to fix this is to put some insulation around the pipe, or if the pipe is running through a tight fitting hole in the wood framing, cut a notch in the framing so the pipe can expand and then contract without that creaking sound.
Pipes can make noises for a variety of reasons and aren’t always cause for concern but to be sure and save your self headache and money later contact us at 602-635-3360 Mr Rooter Plumbing for a free inspection
