Water Hammering Pipes in Grass Valley, CA.

Dear Banging Pipes in Grass Valley, Ca
This can be tricky. There are a couple things that can cause the water pipes to hammer. First I would check to see if the house has a pressure reducing valve on the water main. It would be installed somewhere along the main line either outside or just inside where the pipe enters the house. A pressure reducing valve uses a rubber diaphragm to regulate the incoming water pressure. Sometimes this diaphragm can become loose or worn and when water runs along it, it will vibrate like a reed on a wind instrument. The easiest way to solve the problem is to replace the pressure regulator with a new one. If this doesn’t solve the problem or if you don’t have a regulator you’ll want to install what’s called a pneumatic hammer arrester into the plumbing system
