What is a Water Hammer Arrestor?
A Water Hammer Arrestor is a plumbing device designed to reduce the noise and vibrations caused by water hammer, which is a common problem in plumbing systems. Water hammer occurs when the flow of water in a pipe is abruptly stopped or redirected, causing a sudden increase in pressure. This sudden increase in pressure can create a loud banging or knocking sound, and can also cause damage to pipes, valves, and other plumbing components.
A Water Hammer Arrestor works by providing a cushion of air or gas that absorbs the shockwaves created by water hammer. It is essentially a sealed chamber that is connected to the plumbing system and contains a compressible gas or air. When a sudden change in water flow occurs, the water hammer arrestor absorbs the excess pressure, preventing it from being transmitted throughout the plumbing system. This helps to reduce noise and vibrations, and also protects the plumbing system from damage.
Water Hammer Arrestors can be installed at various points in a plumbing system, such as near appliances like washing machines or dishwashers, at the point where the main water supply enters the building, or at specific problem areas where water hammer is known to occur. The location of the water hammer arrestor will depend on the specific plumbing system and the severity of the water hammer problem. It is important to consult a professional plumber to determine the best location for a water hammer arrestor in your specific plumbing system.
A water hammer arrestor is an essential component in any plumbing system as it helps to prevent damage and reduce noise caused by water hammer. By installing a water hammer arrestor in the optimal location, you can ensure the smooth and efficient operation of your plumbing system while minimizing the potential for costly repairs and disruptions.
Importance of Proper Placement
I’ve learned that proper placement of water hammer arrestors is crucial for their effectiveness in reducing the impact of water hammer in plumbing systems. Installing them in the right locations can significantly minimize the noise and vibrations caused by the sudden stopping or starting of water flow.
One important factor to consider when determining the placement of water hammer arrestors is their proximity to the source of the water hammer. Ideally, they should be installed as close as possible to the valves or fixtures that are prone to causing water hammer. This ensures that the arrestors can quickly absorb and dissipate the pressure surge generated during the water flow changes.
Additionally, it is essential to place water hammer arrestors in accessible areas to ensure ease of maintenance and inspection. By locating them where they are readily visible and reachable, it becomes convenient to check for any signs of damage or wear and tear. This allows for timely repairs or replacements, ensuring the continuous effectiveness of the water hammer arrestors.
In conclusion, proper placement of water hammer arrestors is crucial to reduce the impact of water hammer in plumbing systems.

2. Access for Maintenance
Another important factor to consider is the accessibility of the water hammer arrestor for future maintenance and inspection. The location should be easily accessible so that if any issues arise, the arrestor can be quickly checked, repaired, or replaced. It is also important to ensure that there is enough space around the arrestor for any necessary installation or removal.
3. Compatibility with Plumbing System
Additionally, the location of the water hammer arrestor should be compatible with the existing plumbing system. This includes considering the type and size of the pipes, fittings, and connections in the area. The arrestor should be installed in a location that allows for proper integration into the plumbing system without causing any restrictions or disruptions to the water flow.
4. Noise and Vibration Considerations
Noise and vibration can also be factors to consider when determining the best location for a water hammer arrestor. Installing the arrestor in a location that minimizes noise and vibration levels can help improve the overall comfort and efficiency of the plumbing system. This may involve considering the proximity to living spaces or sensitive equipment that could be affected by excessive noise or vibrations.
5. Building Codes and Regulations
Lastly, it is important to consider any building codes or regulations that may dictate the installation requirements for water hammer arrestors. These codes and regulations may specify the minimum distance that the arrestor needs to be from certain fixtures or appliances, or may outline specific installation guidelines. Adhering to these requirements will help ensure that the water hammer arrestor is installed correctly and in compliance with the applicable standards.
Common Locations for Water Hammer Arrestor
Water hammer arrestors are important devices in plumbing systems that help to control the damaging effects of water hammer. These devices absorb the shock waves created by the sudden stoppage or change in direction of water flow, preventing excessive pressure and potential damage to pipes and fixtures. While there are several possible locations for water hammer arrestors, the following are some of the most common:
1. Near Shut-off Valves:
One common location for water hammer arrestors is near shut-off valves, such as those found under sinks or behind toilets. These valves are often the source of sudden stops or changes in water flow, making them an ideal location to install a water hammer arrestor. By placing the arrestor near the shut-off valve, it can effectively absorb the shock waves and prevent damage to the plumbing system.
2. At the Entrance to Appliances:
Water hammer arrestors can also be installed at the entrance to appliances, such as washing machines or dishwashers. These appliances often have solenoid valves that quickly open and close, causing water hammer. Installing a water hammer arrestor at the appliance’s entrance can help to minimize the pressure fluctuations and protect the plumbing system from damage.
3. By the Main Water Supply:
Another common location for water hammer arrestors is near the main water supply, where the water enters the house or building. Installing an arrestor at this location can help to control water hammer throughout the entire plumbing system. This is especially important in larger buildings or homes with complex plumbing systems, as it ensures that all areas of the system are protected from the damaging effects of water hammer.
In conclusion, water hammer arrestors can be installed in various locations within a plumbing system to effectively control water hammer.
