Web Form: Good morning. My name is Kevin. About two months ago I put in a ureport stating that my pipes were vibrating. You sent someone out and they checked and there was no air in the pipes. Since then I have had two plumbers out and also American Leak Detection to verify there was not a leak. They have not been able to find any issues with anything in my house. They thought it was an issue with the new water heater that was put in. They removed the water heater from the water system and the issue continued. The issue that I am having is that sometimes I will hear vibrating in the pipes and other times it will sound like a car engine running. Sometimes it will last a few seconds and then stop other it will last hours. The starts randomly. I will go to bed and nothing and when I wake up it will be making the noise. The issue will stop once I shut the water to the house off. Also if I check my water usage, I am using no water. If I check my neighbors which is in the same hole as mine their water meter is running about a gallon a minute when my pipes are making the noise. When my pipes are quiet their water is not moving at all. If you have any ideas what could be causing the issue please let me know. We have checked everything in my house and no plumber was able to find anything wrong. If you need to reach me my number is 920-933-9101 and I will be home all day tomorrow Friday April 26.
