Question: Pipes Vibrate When Hot Water Is Turned On

Pipe Expansion As you run the faucet’s hot water, hotter water flows into the pipe. This new water can quickly heat up the pipe, causing it to expand so quickly it vibrates. The vibrations die down after you run the faucet’s hot water for several minutes, but they reappear when you use the hot water again.

Why do my hot water pipes vibrate and make a loud noise when turned on?

A water hammer (also called hydraulic shock) happens when rapidly flowing water slams into a closed valve in the plumbing system. When the water suddenly comes to a stop, it creates very loud vibrations. Most home plumbing systems have air chambers that provide pressure release to lessen the force of a water hammer.

Usually, well water pulsates when there isn’t enough air pressure in the tank.

What causes rumbling in water pipes?
