What is Water Hammer?

Water hammer is a plumbing problem that occurs when a sudden change in water flow causes a shock wave to travel through the pipes. This can be caused by a variety of things, such as a toilet flushing, a faucet being turned on or off, or a water main being shut off.

The shock wave can cause the pipes to vibrate and make a loud banging noise. It can also damage the pipes and fittings, and in some cases, it can even cause a water leak.

Causes of Water Hammer

There are a number of things that can cause water hammer, including:

  • Sudden changes in water flow. This is the most common cause of water hammer. It can happen when a faucet is turned on or off quickly, or when a toilet flushes.
  • Air in the pipes. Air in the pipes can create a vacuum that can cause the water to flow back and forth rapidly. This can lead to water hammer.
  • Clogged pipes. Clogged pipes can restrict the flow of water, which can also lead to water hammer.
  • Defective valves. Defective valves can allow water to flow back and forth rapidly, which can cause water hammer.
  • Low water pressure. Low water pressure can cause the water to flow more slowly, which can also lead to water hammer.

How to Stop Water Hammer

There are a number of things you can do to stop water hammer, including:

  • Install a water hammer arrestor. A water hammer arrestor is a device that absorbs the shock wave and prevents it from damaging the pipes.
  • Install a check valve. A check valve prevents water from flowing back and forth in the pipes. This can help to reduce the risk of water hammer.
  • Fix any leaks or clogs in the pipes. Leaks and clogs can restrict the flow of water and lead to water hammer.
  • Replace any defective valves. Defective valves can allow water to flow back and forth rapidly, which can lead to water hammer.
  • Increase the water pressure. Low water pressure can cause the water to flow more slowly, which can also lead to water hammer.

Water hammer is a common plumbing problem that can be caused by a variety of things. However, it can be prevented by taking steps to reduce the risk of sudden changes in water flow, air in the pipes, clogged pipes, defective valves, and low water pressure.

If you are experiencing water hammer, there are a number of things you can do to stop it, including installing a water hammer arrestor, installing a check valve, fixing any leaks or clogs in the pipes, replacing any defective valves, and increasing the water pressure.

How to Stop Water Hammer

Water hammer is a loud, banging noise that can occur when a faucet is turned on or off, or when a toilet is flushed. It happens when the water flow is suddenly interrupted, and the water pressure in the pipes surges. This surge can cause the pipes to vibrate and bang against each other, creating a loud noise.

Water hammer can be a nuisance, but it can also damage your pipes and fixtures. If you’re experiencing water hammer, there are a few things you can do to stop it.

1. Install a water hammer arrestor

A water hammer arrestor is a device that absorbs the shock of the water flow, preventing the pipes from vibrating and banging. Water hammer arrestors are available at most hardware stores.

To install a water hammer arrestor, follow these steps:

1. Turn off the water to the affected area.
2. Locate the main water supply valve.
3. Connect the water hammer arrestor to the water supply valve.
4. Turn on the water to the affected area.

2. Check for leaks

Leaks can also cause water hammer. If you have a leak, the water will be flowing out of the pipes at a faster rate than it’s coming in, which can create a surge in water pressure.

To check for leaks, follow these steps:

1. Look for any signs of water damage, such as dampness, mold, or water stains.
2. Listen for any dripping or running noises.
3. Feel around the pipes for any warm or wet spots.

If you find a leak, fix it as soon as possible.

3. Upgrade your plumbing

If you have old, outdated plumbing, it’s more likely to experience water hammer. Upgrading your plumbing to newer, more efficient pipes can help to reduce the risk of water hammer.

To upgrade your plumbing, you will need to contact a licensed plumber.

4. Use aerators

Aerators are devices that are installed on faucets to reduce the flow of water. This can help to prevent water hammer by reducing the surge in water pressure.

To install an aerator, follow these steps:

1. Turn off the water to the faucet.
2. Remove the old faucet aerator.
3. Insert the new faucet aerator into the faucet.
4. Turn on the water to the faucet.

5. Use a pressure regulator

A pressure regulator can help to reduce the water pressure in your home, which can help to prevent water hammer.

To install a pressure regulator, follow these steps:

1. Turn off the water to your home.
2. Locate the main water supply valve.
3. Connect the pressure regulator to the water supply valve.
4. Turn on the water to your home.

DIY Solutions for Water Hammer

In addition to the professional solutions listed above, there are a few DIY solutions that you can try to stop water hammer.

  • Use a towel or rag to dampen the noise. If you have a leaky faucet, you can dampen the noise by placing a towel or rag around the faucet. This will help to absorb the sound of the water dripping.
  • Install a water cushion. A water cushion is a device that is placed between the faucet and the sink. It helps to absorb the shock of the water flow, preventing the pipes from vibrating and banging.
  • Use a rubber gasket. A rubber gasket can be placed around the faucet to create a seal. This will help to prevent water from leaking out of the faucet and causing water hammer.

These are just a few of the DIY solutions that you can try to stop water hammer. If you’re unable to stop the water hammer on your own, you should contact a licensed plumber for help.

Water hammer can be a nuisance, but it can also be a sign of a problem with your plumbing. If you’re experiencing water hammer, it’s important to take steps to stop it. By following the tips in this article, you can help to prevent water hammer and protect your plumbing.
