When your home’s plumbing system is operating properly, it shouldn’t make any significant noises. If you notice a loud banging sound when you turn off a faucet, this is a problem known as water hammer. There are a few different methods your plumber can use to fix this problem and prevent it in the future. Below, learn about this issue to keep your plumbing in quality condition.

Frequently Asked Questions About Water Hammer

What is water hammer?

Water hammer occurs when the flow of water in a system stops suddenly. This causes it to bang against the pipe walls and create a shock that reverberates throughout your home. The pipe may even bang against other pipes or framing elements of your home, making an even louder noise.

What causes it?

Basically, water hammer occurs when there’s a sudden buildup of water pressure inside a pipe. When a plumbing system is working properly, there are air pockets inside the pipes that relieve pressure and prevent the shock waves caused when water stops properly. However, water can get into these chambers, thus raising pressure and creating the noise.

How is it fixed?

Your plumber can often reset the air chambers throughout your system by turning off your water supply and opening valves to drain them. Some older plumbing systems may not have these air chambers installed, so your plumber may need to add valves throughout your system to reduce the pressure. In rare cases, they may also need to regulate your home’s water pressure with a pressure gauge or replace old pipes.

What happens if I ignore it?

Water hammer isn’t just an annoying noise, it’s also indicative of pressure buildup inside your pipes. Eventually, the banging against pipe walls may weaken them, which could create erosion or even burst pipes. It’s best to call a plumber as soon as you notice the noise to avoid serious plumbing and water damage.
