What Is Water Hammer?

Water hammer is a loud banging or thumping sound that you may hear in your pipes. This happens when water in the pipes moves quickly and suddenly comes to a stop. When the water stops, it creates shock waves, which cause the pipes to vibrate. This is what creates the hammering sound.

Water hammer can occur in any plumbing system, whether in homes or businesses. It is more common in older pipes that may not be as secure.

Common Causes of Hammering Sounds

Many things can cause that annoying hammering sound. Here are some of the most common:

Sudden Changes in Water Flow

When you turn on or off a tap quickly, it can create a shock wave in the pipes. This sudden change in flow can lead to the hammering sound.

High Water Pressure

If your water pressure is too high, it can create excessive force in your pipes. This pressure can cause pipes to move and create noise.

Air Trapped in Pipes

Sometimes, air can get trapped in your pipes. When water rushes through, this air can cause a knocking sound. This occurs more often if your pipes are not properly installed.

Poorly Supported Pipes

Pipes that are not secured properly can move around. When water flows through them, this movement can create a banging sound.

Faulty Valve

A valve that does not work properly can also cause water hammer. If a valve closes too quickly, it can create the shock wave that leads to noise.

How to Fix Hammering Sounds

Fixing the hammering sound in your pipes might be simple. Here are some steps you can take to solve the problem:

Check Your Water Pressure

First, check the water pressure in your home. You can buy a water pressure gauge from a hardware store. Ideally, your water pressure should be between 40 and 60 psi. If it is too high, you may need to install a pressure-reducing valve.

Install Water Hammer Arresters

Water hammer arresters are devices that can help stop the noise. These devices absorb the shock wave created when water stops suddenly. You can find them at local hardware stores.

• How to install: It is best to have a plumber install them. They go near the valves or faucets where you hear the noise.

Secure Loose Pipes

Check to see if your pipes are secure. If you find loose pipes, use pipe straps or hangers to secure them. This can help reduce movement and noise.

Remove Air Traps

If you suspect air is trapped in your pipes, you can try to remove it. Locate the highest faucet in your home. Turn it on and let the water run for a few minutes. This can help push the air out.

Call a Professional

If you have tried these fixes and still hear that hammering sound, you should call a plumber. They can diagnose the problem and recommend the best solutions.

Signs of a Bigger Problem

Sometimes, a hammering sound can be a sign of a more serious issue. Here are some signs you should look for:

Frequent Hammering

If the noise happens all the time, it could mean there is a bigger plumbing problem.

Leaking Pipes

If you notice water stains or leaks, your pipes may be damaged. This could cause water hammer.

Low Water Pressure

If your water pressure suddenly drops, this can create problems.

Unusual Noises

If you hear other strange sounds, like gurgling or bubbling, you should call a plumber.

Additional Context on Water Hammer

Cause	Description	Solution
Sudden Valve Closure	Rapid closure of a valve can create shock waves.	Install slow-closing valves.
Temperature Changes	Heating and cooling can cause pipes to expand and contract.	Insulate pipes to minimize temperature effects.
Pipe Diameter Changes	Sudden changes in pipe diameter can create turbulence.	Ensure consistent pipe sizes throughout.

Preventing Water Hammer Issues

Preventing water hammer is easier than fixing it. Here are some tips to help you avoid the problem:

Regular Maintenance

Have your plumbing checked regularly. A plumber can find and fix potential problems before they become serious.

Install Water Hammer Arresters During New Builds

If you are building a new home, consider installing water hammer arresters right away. This can save you from future headaches.

Monitor Water Pressure

Keep an eye on your water pressure, especially if you notice changes in noise.

Ensure Proper Pipe Support

Make sure all pipes in your home are well-supported. This will help prevent movement and noise.

Additional Considerations for Homeowners

• Conduct routine checks on your plumbing system.
• Keep an eye out for visible signs of wear or damage on pipes.
• Be aware of changes in water pressure or unusual noises.

When to Seek Help

Sometimes, it can be hard to know when to call a plumber. If you are not sure, it’s better to be safe than sorry. Here are some situations when you should reach out for help:

• If you hear persistent hammering sounds.
• If your water pressure is consistently too high or too low.
• If you notice leaks or water stains.
• If you are unsure how to fix the issue.

Calling a plumber can save you time and effort. They can ensure everything is fixed properly.
