How to install a water hammer arrester on a basin faucet?
Oct 24, 2025
Hey there! As a basin faucet supplier, I've seen my fair share of plumbing issues, and one of the most common ones is the dreaded water hammer. You know that loud, banging noise you hear in your pipes when you turn off the water? That's water hammer, and it can be a real pain in the neck. But don't worry, I'm here to show you how to install a water hammer arrester on a basin faucet and put an end to that annoying noise once and for all.
What is a Water Hammer Arrester?
Before we dive into the installation process, let's quickly go over what a water hammer arrester is and how it works. A water hammer arrester is a device that's designed to absorb the shock waves created by the sudden stop of water flow in your pipes. When you turn off a faucet or a valve, the water in the pipes comes to a sudden halt, creating a pressure wave that travels through the pipes and causes that banging noise. A water hammer arrester acts as a cushion, absorbing the pressure wave and preventing it from causing damage to your pipes and fixtures.


Tools and Materials You'll Need
Now that you know what a water hammer arrester is, let's talk about the tools and materials you'll need to install one on your basin faucet. Here's a list of what you'll need:
- Water hammer arrester
- Adjustable wrench
- Teflon tape
- Pipe cutter (if necessary)
Step-by-Step Installation Guide
Okay, now that you have all the tools and materials you need, let's get started with the installation process. Here's a step-by-step guide on how to install a water hammer arrester on a basin faucet:
Step 1: Turn Off the Water Supply
The first thing you need to do is turn off the water supply to your basin faucet. You can usually find the shut-off valves under the sink. Turn the valves clockwise until they're fully closed.
Step 2: Drain the Pipes
Once you've turned off the water supply, open the faucet to drain any remaining water from the pipes. This will help prevent any water from spilling out when you start working on the pipes.
Step 3: Locate the Faucet Supply Lines
Next, you need to locate the faucet supply lines. These are the pipes that connect the faucet to the water supply. They're usually made of flexible plastic or metal and are located under the sink.
Step 4: Install the Water Hammer Arrester
Now it's time to install the water hammer arrester. Here's how you do it:
- Choose the Right Location: The water hammer arrester should be installed as close to the faucet as possible. This will ensure that it can effectively absorb the pressure waves created by the sudden stop of water flow.
- Cut the Supply Line (if necessary): If the supply line is too long, you may need to cut it to the appropriate length. Use a pipe cutter to make a clean cut.
- Apply Teflon Tape: Wrap a few layers of Teflon tape around the threads of the water hammer arrester and the supply line. This will help create a watertight seal.
- Connect the Water Hammer Arrester: Use an adjustable wrench to connect the water hammer arrester to the supply line. Tighten the connection until it's snug, but be careful not to overtighten it.
Step 5: Repeat the Process for the Other Supply Line
If your basin faucet has two supply lines (hot and cold), you'll need to repeat the installation process for the other supply line. Make sure to install a water hammer arrester on both supply lines to ensure maximum protection.
Step 6: Turn On the Water Supply
Once you've installed the water hammer arresters on both supply lines, it's time to turn on the water supply. Slowly turn the shut-off valves counterclockwise until they're fully open. Check for any leaks around the connections. If you notice any leaks, tighten the connections a little more.
Step 7: Test the Faucet
Finally, turn on the faucet and let the water run for a few minutes. Check for any signs of water hammer. If you still hear the banging noise, you may need to adjust the position of the water hammer arresters or replace them with a different type.
Benefits of Installing a Water Hammer Arrester
Installing a water hammer arrester on your basin faucet has several benefits, including:
- Prevents Pipe Damage: Water hammer can cause damage to your pipes over time, leading to leaks and other plumbing problems. By installing a water hammer arrester, you can prevent this damage and extend the lifespan of your pipes.
- Reduces Noise: The loud, banging noise caused by water hammer can be annoying and disruptive. Installing a water hammer arrester will eliminate this noise and make your home a more peaceful place to live.
- Improves Water Flow: Water hammer can also cause a decrease in water flow, making it difficult to use your faucet. By absorbing the pressure waves, a water hammer arrester can improve water flow and ensure that your faucet works properly.
