My pipes are a little touchy feely.
My neighbor recently installed a sprinkler system in his yard and now my pipes make a knocking noise when his sprinklers are running. The noise is coming from the pipes where the water enters the home. Now my pipes even knock when I turn on my outside water. My MUD guy came out and looked it over and thinks mine and my neighbors pipes are running too close together or possibly touching at some point. He also checked and they are not hooked up to my water line. How do I stop the noise?
