A water hammer is caused by fast-closing valves, like toilet fill valves and faucets. As the water flows through the pipes and the valve shuts off quickly, it causes the water to stop suddenly in the pipes, causing the “hammer” effect. Once the lowest pipe runs clear, close that drain and turn the water main back on.

What causes vibrations in water pipes?
When water pressure is too high, water pipes can vibrate randomly. This is because the increased pressure within the lines has caused pipe fittings to loosen. To troubleshoot this issue, you need to check your water pressure regulator. Keep water pressure set between 40 and 60 psi – adjust the regulator if necessary.
