Quieting Noisy Water Pipes

quieting water pipesWater flowing in pipes can cause all kinds of weird noises. We all know what water running through a pipe sounds like, but what about some of those other plumbing sounds – like creaks or cracking sounds, rattling, whistling and the most annoying or scary of them all, that loud banging noise? Let’s look at what causes those sounds and how you can fix them.

Creaks or a cracking sound
These are usually caused by the expansion and contraction of the water pipes themselves. As hot water runs through a pipe, it naturally heats the pipe, causing it to expand slightly. 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.
