My pipes rattle, shake and I hear a loud knocking when I turn my water on. What causes this?


That is called a water hammer.


Water hammer is a vibration in the pipes.

Water hammer has many causes:

  • A hot water tank with its temperature set too high.
  • A loose washer in a valve or faucet.
  • Water pipes not securely fastened.
  • Faulty parts in toilets.
  • Air in the lines from a repair on a water main or someone using a hydrant.
