How to Easily Install a Water Hammer Arrestor Under Your Sink
Have you ever experienced a loud banging noise after turning off the water in your sink? That annoying sound, known as water hammer, can be a real headache. Fortunately, there’s a simple solution: installing a water hammer arrestor. In this guide, we’ll show you how to easily install a water hammer arrestor under your sink, saving you from those dreadful banging noises and potential plumbing damage.
What is a Water Hammer Arrestor
Before we dive into the installation process, let’s quickly cover what a water hammer arrestor is and why it’s essential. A water hammer arrestor is a small device that absorbs the shock caused by sudden changes in water flow. When you turn off a faucet, the water’s momentum can create a shockwave, resulting in the dreaded banging noise. The water hammer arrestor acts as a cushion, preventing this shockwave and protecting your plumbing system.
Step 1: Gather Your Tools and Materials
To start with the installation process, you’ll need a few tools and materials. Here’s a list of what you’ll need:
- Adjustable wrench
- Pipe cutter or hacksaw
- Teflon tape
- Water hammer arrestor (make sure it matches the pipe size)
- Pliers
Make sure you have all these items handy before you begin, ensuring a smooth installation process.
Step 2: Shut Off the Water Supply
Safety first! Before getting your hands dirty, turn off the water supply to your sink. Locate the shut-off valve under or near the sink and twist it clockwise until fully closed. If you can’t find a specific shut-off valve for your sink, you may need to shut off the main water supply to your house.
Step 3: Drain the Water
To avoid any messy surprises, it’s crucial to drain any remaining water in the pipes before installing the water hammer arrestor. Simply turn on the faucet and let the water run until it flows out completely. Don’t forget to place a bucket or towel beneath the pipes to catch any drips.
Step 4: Remove the Existing Pipe
Now it’s time to remove the section of pipe where you’ll be installing the water hammer arrestor. Using a pipe cutter or hacksaw, carefully cut out a small portion of the pipe. Make sure the cut is clean and smooth, and remove any burrs or sharp edges with a file.
Step 5: Install the Water Hammer Arrestor
Apply a few layers of Teflon tape to the threaded ends of the water hammer arrestor. This will help create a watertight seal when you screw it into place. Use an adjustable wrench to secure the water hammer arrestor onto the pipe fittings, ensuring it’s tightly fastened. If there are any extra threaded connections, use pliers or an adjustable wrench to tighten them as well.
Step 6: Test for Leaks
Now that you’ve installed the water hammer arrestor, it’s time to test for leaks. Turn on the water supply to the sink and observe the pipes carefully. Look for any signs of dripping or leakage around the newly installed water hammer arrestor. If you spot any leaks, tighten the connections further until the leaks stop.
That’s it! You’ve successfully installed a water hammer arrestor under your sink. Say goodbye to those annoying banging noises and protect your plumbing system from potential damage.
Remember, if you’re unsure about any step of the installation process or encounter difficulties, it’s always a good idea to consult a professional plumber. However, with these simple steps, you should be well-equipped to tackle this DIY project and enjoy a quieter, more peaceful sink experience.
Now go ahead, turn on your faucet, and revel in the silence!

Does PEX Have Water Hammer
Ah, good ol’ PEX pipes. They’ve revolutionized plumbing in many ways. But do they experience water hammer? The answer is both simple and pleasant: not really. Due to their flexible and shock-absorbing nature, PEX pipes naturally minimize the occurrence of water hammer. However, it’s still good practice to install a water hammer arrestor to provide an extra layer of protection and ensure peace of mind.
Why Do I Need a Water Hammer Arrestor
In a nutshell, you need a water hammer arrestor to prevent those annoying and potentially damaging knocking noises that occur in your plumbing system. Water hammer, which is caused by the sudden change in water flow, can lead to pipe damage, fixture wear, and even annoying vibrations. A water hammer arrestor acts as a shock absorber, reducing the pressure and preventing these undesirable effects. So, think of it as the plumbing equivalent of a superhero, swooping in to save the day (and your pipes).
How Do I Stop My Pipes From Shaking
If your pipes are shaking like there’s an earthquake happening inside your walls, it’s likely due to water hammer. But fear not, here are a few steps you can take to stop your pipes from doing the jitterbug:
-
Install a water hammer arrestor: This is the most effective way to dampen those vibrations and restore calm to your plumbing system.
-
Secure loose pipes: If your pipes are not properly anchored, they can shake and rattle when water flow changes. Secure them with brackets or straps to keep them steady.
-
Cushion pipe connections: Apply foam pipe insulation or rubber washers at points where pipes connect to fixtures or walls. This helps absorb vibrations and reduces noise.
-
Adjust water pressure: High water pressure can contribute to water hammer. Consider installing a pressure regulator if your water pressure is consistently high.
How Long Should Plumbing Air Chambers Be
Plumbing air chambers play a vital role in preventing water hammer, but how long should they be? Ideally, air chambers should be around 12 inches in length. This length provides sufficient space for the cushion of air to absorb the pressure changes and minimize the hammer effect. So, when it comes to air chambers, remember, size (or length) does matter.
How Do You Fix Water Hammer in Plumbing Pipes
Water hammer got you down? No worries! Follow these simple steps to fix it:
- Turn off the water supply to the affected area.
- Open all faucets and drain the remaining water.
- Locate the water hammer arrestor, typically found near the fixture causing the issue.
- If it’s an older hammer arrestor, drain and recharge it with air. If it’s damaged, replace it.
- Before putting everything back together, ensure that any loose pipes are properly secured and any damaged valves are replaced.
- Turn the water supply back on and enjoy your peaceful, hammer-free plumbing system.
How Do You Recharge Plumbing Air Chambers
Over time, the air cushion in plumbing air chambers may become depleted, reducing their effectiveness. To recharge them, follow these simple steps:
- Turn off the water supply to the area with the affected air chamber.
- Open the highest and lowest faucets in your home to drain the water.
- Locate the air chamber and remove the cap or plug.
- Using a bicycle pump or air compressor, gently apply air to the chamber until it reaches the recommended pressure (typically around 80 psi).
- Replace the cap or plug on the air chamber and turn the water supply back on.
- Voila! Your air chamber is now recharged and ready to take on water hammer like a champ.
Are Water Hammer Arrestors Needed with PEX
PEX pipes are a popular choice for plumbing nowadays, but do you still need a water hammer arrestor with them? Absolutely! While PEX pipes naturally minimize water hammer due to their flexible nature, they don’t eliminate it entirely. Installing a water hammer arrestor with PEX pipes provides an additional layer of protection and peace of mind, ensuring a quiet and harmonious plumbing system.
Where Should a Water Hammer Arrestor Be Placed
A water hammer arrestor should be installed as close to the source of the water hammer as possible. Typically, this means near the fixture or appliance that causes the disruptive noise. By placing the water hammer arrestor at the point of impact, you’re effectively attacking the problem at its root and mitigating any potential damage or annoyance.
Where Do You Put the Air Chamber
When it comes to installing an air chamber, placement is key. To ensure optimal performance, the air chamber should be placed at the highest point in the system where water flow changes direction. This strategic positioning allows the air chamber to absorb pressure fluctuations and prevent water hammer from disrupting your plumbing tranquility.
When Would You Use a Hammer Arrestor
A water hammer arrestor is your trusty sidekick whenever you encounter the ominous thumping or banging sounds in your plumbing system. Any time you experience water hammer, whether it’s during a sudden faucet closure or the operation of a water-using appliance, a hammer arrestor is your go-to solution. So, whenever you hear those unwelcome banging noises, remember to call on your trusty hammer arrestor to save the day.
Do You Need a Water Hammer Arrestor for Kitchen Sink
Ah, the heart of the home – the kitchen sink. Do you need a water hammer arrestor specifically for your kitchen sink? The answer is a resounding yes! While water hammer can occur throughout your plumbing system, the kitchen sink is often a culprit due to the frequent use and sudden changes in water flow. Installing a water hammer arrestor under your kitchen sink is a wise move to keep water hammer at bay and ensure a peaceful cooking and cleaning experience.
Is There a Whole House Water Hammer Arrestor
If you’re a fan of all-in-one solutions, you might be wondering if there’s a whole house water hammer arrestor available. The answer is both simple and delightful: yes, there is. Whole house water hammer arrestors are designed to protect your entire plumbing system from the wrath of water hammer. By installing a single unit at the cold water supply line, you can achieve peace and quiet throughout your entire house. It’s like having the Avengers assemble to combat water hammer!
Where Do You Put Water Hammer Arrestor Under Sink
When it comes to installing a water hammer arrestor under your sink, proper placement is essential. The water hammer arrestor should be installed as close to the fixture as possible. This means attaching it to the hot or cold water supply line, just below the sink or within the cabinet. This strategic positioning ensures that the water hammer arrestor can effectively absorb any pressure changes and keep your plumbing quiet and peaceful.
How Long Do Mini Arrestors Last
Mini arrestors, just like their larger counterparts, have an important job to do. Despite their smaller size, they are just as mighty when it comes to combating water hammer. In terms of longevity, mini arrestors can last anywhere from 5 to 10 years, depending on factors such as usage and water quality. However, regular maintenance and inspection are recommended to ensure optimal performance and catch any signs of wear or damage early on.
Do Water Hammer Arrestors Fail
While water hammer arrestors are designed to be reliable and long-lasting, they can occasionally experience failure. Over time, the air cushion inside the arrestor may become depleted or the internal components could malfunction. Signs of failure include recurring water hammer noises or noticeable vibrations. If you suspect your water hammer arrestor has failed, it’s best to consult a professional plumber to assess the situation and recommend the appropriate course of action.
Do Water Hammer Arrestors Need to Be Vertical
Water hammer arrestors are quite flexible when it comes to their orientation. They can be installed both vertically and horizontally without compromising their effectiveness. So, feel free to position your water hammer arrestor in whichever direction makes the installation process more convenient or aesthetically pleasing. However, do ensure that it’s securely attached to prevent any unwanted movement or noise.
