When I run my water I can hear a noise that sounds like it is coming from my plumbing, what could be causing this?

This is a popular question with very few definite answers.

Occasionally the water meter maybe the culprit due to uneven wearing of the internal parts or from debris that has built up inside the meter to interfere with the normal movement of the meter parts. Another possibility is the expansion or contraction of your pipes as they cool or heat. As the pipes expand or contract they can rub or slip within the pipe hangers or clamps. Air bubbles inside your pipes can also cause noise in your plumbing. Whenever work is done on your plumbing, or when we have a water main break, air is let into the plumbing and can cause noise inside the pipes as the bubbles move about.

A solution to this, or to confirm if this is the cause, is to open your faucets and let the water run to remove the trapped air bubbles. Some times the noise is not from the plumbing but from either a water-using device, a pipe that is touching another appliance such as a furnace or washer/dryer or a sump pump. Conducting a complete inspection of your plumbing to provide your plumber or us with more information will help us with finding a solution to your noise problem.
