2. What causes water hammer?
  • Water hammer occurs when the water in the pipe suddenly changes direction, for example when a faucet is turned off. The change in direction creates pressure waves, which can vibrate and “bang” on the pipe, and can cause damage if the pressure is too high. Other causes of water hammer include air trapped in pipes, plumbing design problems (such as poor/improper installation, incorrect fittings used, etc.), and plumbing maintenance problems (such as kinks, corrosion, or other damage to pipes, improper water pressure settings, etc.).
