To install a water hammer arrestor, locate the nearest plumbing fixture and shut off the water supply. Then, attach the arrestor to the supply line using compression fittings and secure it in place.
Understanding Water Hammer And Its Causes
Understanding water hammer and its causes is crucial for homeowners and plumbers alike. Water hammer refers to the loud banging or knocking noise that occurs when a faucet or valve is quickly shut off. This noise can not only be irritating but can also cause damage to your plumbing system over time. In this blog post, we will delve into the details of water hammer, its causes, and how to install a water hammer arrestor to prevent it from happening.
What is water hammer?
Water hammer is a hydraulic shock wave that travels through the water pipes in your plumbing system when there is a sudden change in water flow or pressure. When a faucet or valve is closed rapidly, the flowing water comes to a sudden stop, causing the shock wave to reverberate through the pipes. This shock wave creates a loud banging or knocking noise, which is commonly referred to as water hammer.
How does water hammer occur?
Water hammer typically occurs when there is a sudden change in water flow or pressure. There are several factors that can contribute to the occurrence of water hammer:
- Abrupt valve closure: When a faucet or valve is closed too quickly, it creates an instant stop in water flow, leading to water hammer.
- High water velocity: If water is flowing through the pipes at a high velocity, it can increase the chances of water hammer.
- Long pipe runs: Longer pipe runs provide more room for the shock wave to propagate, making water hammer more likely.
- Poorly secured pipes: If the pipes in your plumbing system are not properly secured or anchored, they can vibrate and amplify the effects of water hammer.
Common causes of water hammer
Water hammer can be caused by various factors, including:
- Residential plumbing systems: In homes, water hammer is commonly caused by sudden changes in water flow due to faucets, toilets, or appliances being turned off quickly.
- Commercial plumbing systems: In larger buildings or commercial settings, water hammer can be caused by the operation of valves, pumps, or other hydraulic systems.
- Water supply issues: Water hammer can also occur due to problems with the municipal water supply, such as sudden pressure surges or changes in water flow.
By understanding the causes of water hammer, you can take the necessary steps to prevent it from happening. Installing a water hammer arrestor is one effective solution that can help in reducing the occurrence of water hammer and protecting your plumbing system from potential damage.

How A Water Hammer Arrestor Works
The Role of a Water Hammer Arrestor
A water hammer arrestor plays a crucial role in preventing water hammer, also known as hydraulic shock, in your plumbing system. When water flow is abruptly stopped or redirected, it creates a shockwave that moves through the pipes, causing a loud banging noise. This shockwave can lead to damage to your pipes, fixtures, and appliances over time. A water hammer arrestor acts as a shock absorber, absorbing the excess pressure created by the shockwave and preventing it from causing any harm.
Components of a Water Hammer Arrestor
A water hammer arrestor consists of several key components that work together to minimize the impact of hydraulic shock:
- Air Chamber: This is the main component of a water hammer arrestor. It is a cylindrical chamber filled with air or gas. When the shockwave occurs, the air in the chamber compresses, absorbing the excess pressure and preventing the shock from damaging the plumbing system. It acts as a cushion, preventing the shockwave from reverberating through the pipes.
- Water Chamber: Connected to the air chamber, the water chamber serves as a buffer between the air and water. It allows water to flow freely while keeping the air separate and compressed in the air chamber.
- Piston: The piston inside the water hammer arrestor moves up and down within the chamber as the shockwave passes through. It helps to regulate the pressure and flow of water, preventing excessive pressure buildup during sudden changes in water flow.
- Sealed Cap: The sealed cap at the top of the water hammer arrestor ensures that the air remains trapped inside the chamber and the system remains pressurized, ready to absorb any future shockwaves.
Types of Water Hammer Arrestors
Water hammer arrestors come in different types, each suitable for specific plumbing system requirements:
| Type | Description |
|---|---|
| Vertical Water Hammer Arrestors | These are the most common type of water hammer arrestors. They are typically installed vertically near faucets, fixtures, or appliances where water hammer is most likely to occur. |
| Horizontal Water Hammer Arrestors | Horizontal water hammer arrestors are installed horizontally, usually in areas where vertical installation is not feasible. They are often used in tight spaces or situations where there is limited vertical clearance. |
| Integral Water Hammer Arrestors | These water hammer arrestors are built into specific fixtures or appliances. They are pre-installed and provide efficient water hammer protection without the need for separate installations. |
By understanding the functioning and components of a water hammer arrestor, and choosing the appropriate type for your plumbing system, you can effectively prevent water hammer and protect your pipes and fixtures from costly damage. Ensure to install or consult a professional plumber for the correct placement and installation of a water hammer arrestor in your plumbing system.
Determining The Appropriate Location For Installation
Factors to consider
Determining the appropriate location for installing a water hammer arrestor is crucial to ensure its optimal functionality. There are several factors to consider before finalizing the installation spot. Taking these factors into account will help eliminate water hammer noises and protect your plumbing system from damage.Guidelines for choosing the right location
To choose the right location for your water hammer arrestor, follow these guidelines: 1. Proximity to the water source: Install the water hammer arrestor as close to the water source as possible. This will enable it to effectively absorb the excess pressure generated by the water flow and prevent any disruptions in the plumbing system. 2. Accessibility: Select a location that allows easy access for future inspection or maintenance. Ensure there is enough space around the water hammer arrestor for smooth installation and troubleshooting, if required. 3. Vertical installation: Mount the water hammer arrestor in a vertical position. This will help ensure proper water flow and maximize its efficiency in controlling the hydraulic shock waves that cause water hammer. 4. Height: Place the water hammer arrestor at a height above the highest faucet or fixture in your plumbing system. This will allow it to absorb the pressure fluctuations throughout the entire system. 5. Securing the arrestor: Use brackets or clips to securely fasten the water hammer arrestor to a stud or any other stable surface. This will prevent unwanted movement or vibrations that may affect its performance.Checking existing plumbing systems
Before installing the water hammer arrestor, it is essential to examine your existing plumbing system to ensure compatibility and proper functioning. Consider the following:- Identify the mains water supply line: Locate the main water supply line coming into your property. This will help determine where to install the water hammer arrestor to effectively control water hammer issues.
- Assess the pipe material: Different pipe materials can have varying levels of resistance to water hammer. It is advisable to use a water hammer arrestor that matches the pipe material to optimize its performance.
- Check for bypass valves: Some plumbing systems may already have built-in bypass valves. Ensure these valves are closed or adjusted properly to direct water flow through the water hammer arrestor for it to be effective.
