Water hammer arrestor on washing machine is a crucial component that plays a vital role in ensuring the smooth operation of washing machines by mitigating the effects of water hammer, a phenomenon that causes sudden and extreme pressure changes in the water supply lines.
Water hammer arrestors help to absorb and dissipate the energy generated during water hammer events, thereby preventing damage to pipes, pumps, and other equipment, and ensuring that the washing machine operates efficiently and effectively.
Understanding Water Hammer Arrestors in Washing Machines
Water hammer arrestors are crucial components in modern washing machines that help prevent water-related damage and ensure smooth operation. These devices play a vital role in mitigating the effects of water hammer, a phenomenon that occurs when a pipe is subjected to sudden and forceful changes in water pressure. In washing machines, water hammer can be particularly problematic due to the high pressure and rapid flow rates involved.
The Function of Water Hammer Arrestors in Washing Machines
Water hammer arrestors are essentially valves that regulate the flow of water into and out of the washing machine. They work by using a specialized design that allows water to flow smoothly through the valve, thus reducing the likelihood of water hammer occurring. When water hammer does occur, the arrestor’s specialized design helps to absorb and dissipate the energy associated with the sudden pressure change, preventing damage to the surrounding pipes and fittings.
The Purpose of Installing Water Hammer Arrestors in Appliances
The primary purpose of installing water hammer arrestors in washing machines and other appliances is to prevent damage caused by water hammer events. These events can result in costly repairs, down-time, and even pose a risk to the safety of the machine’s occupants. By installing a water hammer arrestor, manufacturers can ensure their appliances operate smoothly and efficiently, reducing the risk of damage and associated maintenance costs.
Examples of Washing Machines with Built-In Water Hammer Arrestors
Several popular washing machine models are equipped with built-in water hammer arrestors, including:
- Whirlpool WTW5000DW: This energy-efficient washer features a built-in water hammer arrestor as part of its comprehensive design.
- Bosch WAT28400UC: This high-capacity washer includes a water hammer arrestor to prevent damage and ensure smooth operation.

Types of Water Hammer Arrestors Used in Washing Machines
Washing machines employ various types of water hammer arrestors to mitigate the impact of sudden water pressure changes. These devices play a crucial role in preventing damage to household pipes, fixtures, and equipment. With different designs catering to specific needs, it’s essential to understand the efficiency, effectiveness, and cost implications of each type.
Pilot-Operated Check Valves (POCVs)
POCVs are widely used in washing machines due to their simplicity and effectiveness. They consist of a small pilot valve that regulates the main valve’s opening, preventing excessive flow rates. This design ensures smooth water flow, reducing the likelihood of water hammer incidents.
- Pilot-operated check valves are suitable for washing machines with high water pressure demands.
- POCVs offer excellent noise reduction, as they minimize the impact of water flow changes.
- The cost of POCVs is relatively low compared to other types of water hammer arrestors.
Pressure-Reduction-Type Water Hammer Arresters
These devices use a pressure-reducing valve to regulate water pressure, thereby minimizing the risk of water hammer. They consist of a diaphragm that separates the high-pressure area from the low-pressure area.
Pressure-reduction-type water hammer arresters are commonly used in residential washing machine installations where water pressure is relatively high.
Quick-Acting Valves (QAVs)
QAVs operate quickly to reduce the flow rate when water pressure drops, preventing water hammer incidents. They are often preferred for washing machines with high-speed pumps.
Quick-acting valves are typically more expensive than pilot-operated check valves but offer better performance in high-flow-rate applications.
Installation and Maintenance of Water Hammer Arrestors
Installing a water hammer arrestor in your washing machine is a straightforward process that requires some basic plumbing knowledge and tools. A well-installed water hammer arrestor can help prevent damage to your washing machine and plumbing system.
To install a water hammer arrestor, follow these steps:
Before performing any installation, make sure to turn off the water supply to the washing machine. Use a bucket or container to catch any water that might spill out during the installation process.
Locate the washing machine’s water supply lines and identify the point where the water hammer arrestor will be installed.
Disconnect the water supply lines from the washing machine and attach the water hammer arrestor to the supply lines. Make sure it is securely attached.
Connect the water supply lines to the washing machine, making sure not to over-tighten the connections.
Regular maintenance is crucial to ensure the water hammer arrestor continues to function properly. Here are some tips to help you maintain your water hammer arrestor:
Inspection and Cleaning
Regularly inspect the water hammer arrestor for any signs of damage or wear. Check for mineral buildup, rust, or corrosion on the arrestor’s surface.
Clean the arrestor with a soft brush and mild detergent to remove any debris or mineral deposits. Rinse the arrestor thoroughly and reassemble it.
Replacing Filters (if applicable)
If the water hammer arrestor has a filter, replace it as recommended by the manufacturer. A clogged filter can reduce the effectiveness of the arrestor.
Tightening Connections
Regularly check the connections between the water supply lines and the washing machine to ensure they are tightened properly. Loose connections can cause the water hammer arrestor to malfunction.
Identifying Potential Issues
Be aware of the following potential issues that may affect the performance of your water hammer arrestor:
Incorrect Installation
If the water hammer arrestor is not installed correctly, it may not function properly or may even cause more damage to your washing machine and plumbing system.
Blocked Air Gap
If the air gap between the water supply lines and the washing machine is blocked, it can cause the water hammer arrestor to malfunction.
Mineral Buildup
Mineral buildup on the arrestor’s surface can reduce its effectiveness. Regular cleaning can help prevent this issue.
