Reply To: Air in water pipes

: I have recently placed an addition on the front portion of our house, the old water pipe came through the front of the house. I redirected this pipe using 1/2 inch galvanized water pipe an adapter and approximately 12 feet of pipe (in 6 foot sections. at the end of the line, I have a typical shut off I use for the garden hose and washing our vehicles. My question is this? Since the summer months began, I am getting a lot of rattling through this pipe when its in use. I would like to know how to stop it, even if it means cutting through the finished wall to do it. I would really appreciate any help you can give me. Thanks.Jim, Places to look would be: Any valves, sometimes the stems will flutter and create noise (have someone hold the valve handle when the noise occurs to see if anything changes)If the pipe shudders, check the rubber seals on the valves ( a loose washer will sound like a tuba)Pipes that are loose (pipes should be strapped to prevent movement)Air chambers on the piping system will help reduce the clunking that can occur when valves are shut off quickly.Best regards, Terry Love
