What is a Water Hammer Arrestor and Why is It Important for Your Dishwasher?
Best practices for selecting and installing a water hammer arrestor involve assessing the specific needs of the plumbing system and appliance. It is advisable to consult with a plumbing professional to determine the appropriate type and size of the arrestor, ensuring it is installed at the right location to effectively mitigate water hammer. Regular maintenance checks can also help ensure that the arrestor remains functional over time, providing ongoing protection for your dishwasher and plumbing system.
How Does a Water Hammer Arrestor Work to Prevent Damage?
A water hammer arrestor is a device designed to absorb the shock waves created when a faucet or appliance, such as a dishwasher, is rapidly closed, preventing potential damage to plumbing systems.
- Air Chamber: The basic mechanism within a water hammer arrestor consists of an air chamber that compresses air to absorb shock.
- Construction Materials: Water hammer arrestors are typically made from durable materials such as brass or stainless steel, ensuring longevity and resistance to corrosion.
- Installation Location: Proper placement of the arrestor is crucial; it is usually installed near the water supply line of the appliance to effectively dampen the shock waves before they travel through the plumbing.
- Maintenance-Free Design: Many modern water hammer arrestors are designed to be maintenance-free, requiring no regular checks or refills of air, making them convenient for homeowners.
Air Chamber: The air chamber in a water hammer arrestor serves as a cushion for the water flow. When water flow is suddenly stopped, the air inside the chamber compresses, absorbing the energy of the shock wave and preventing it from propagating through the pipes, thereby reducing noise and potential damage.
Construction Materials: The materials used in constructing a water hammer arrestor are essential for its durability and effectiveness. Brass and stainless steel provide a robust structure that can withstand high pressure and resist corrosion, ensuring that the arrestor functions properly over time, especially in environments with varying water temperatures.
Installation Location: The effectiveness of a water hammer arrestor greatly depends on its installation location. Ideally, it should be placed as close to the source of the water hammer as possible, such as near a dishwasher or washing machine, allowing it to intercept shock waves before they can travel throughout the plumbing system.
Maintenance-Free Design: Many contemporary water hammer arrestors are designed to be maintenance-free, eliminating the need for homeowners to periodically check or refill air in the device. This feature not only saves time but also ensures that the device remains functional without the risk of it being neglected or forgotten.
What Features Should You Look for When Choosing a Water Hammer Arrestor for Your Dishwasher?
When choosing a water hammer arrestor for your dishwasher, consider the following key features:
- Size: The size of the water hammer arrestor is crucial because it must fit your plumbing system and have the capacity to absorb the shock effectively. A larger unit generally provides better performance, but it should still fit within the available space under your sink or near the dishwasher.
- Material: The material of the arrestor affects its durability and effectiveness. Brass and stainless steel are popular choices due to their resistance to corrosion and ability to withstand high water pressures, while plastic models may be lighter and less expensive but can be less durable over time.
- Pressure Rating: The pressure rating indicates the maximum water pressure the arrestor can handle. It is essential to choose a model that matches or exceeds your home’s water pressure to ensure it functions properly and protects your plumbing from potential damage.
- Type of Arrestor: There are two main types of water hammer arrestors: piston-type and diaphragm-type. Piston arrestors are generally more efficient at absorbing shock, while diaphragm models may be more compact and easier to install, so consider your specific needs and preferences when choosing.
- Installation Ease: Look for an arrestor that is easy to install, preferably one that comes with clear instructions or mounting hardware. Some models are designed for direct installation onto existing plumbing without requiring specialist tools, making them more user-friendly for DIY enthusiasts.
- Maintenance Requirements: Consider how much maintenance the arrestor will need over its lifespan. Some models are designed to be maintenance-free, while others may require periodic checks or replacements, which could affect long-term convenience.
- Brand Reputation: Opt for products from reputable brands known for quality and reliability. Researching customer reviews and ratings can provide insight into the performance and longevity of various models, helping you make an informed choice.

What Are the Common Problems a Water Hammer Arrestor Can Solve for Dishwashers?
The common problems that a water hammer arrestor can solve for dishwashers include:
- Water Hammer Noise: Water hammer occurs when a sudden stop in water flow creates a shockwave, leading to loud banging noises in pipes.
- Pipe Vibration: The force of the water hammer can cause vibrations in the plumbing, potentially damaging pipes and fittings over time.
- Pressure Fluctuations: Sudden changes in water pressure can disrupt the dishwasher’s operation, leading to inefficient cleaning and water usage.
- Potential Damage to Appliances: The stress caused by water hammer can lead to premature wear or failure of the dishwasher or other connected appliances.
Water Hammer Noise: This is the most noticeable issue, as the loud banging sound can be alarming and disruptive. A water hammer arrestor absorbs the shock created by the fast-moving water, effectively dampening the noise and creating a quieter kitchen environment.
Pipe Vibration: The vibrations caused by water hammer can reverberate through the plumbing system, leading to loose fittings or even pipe bursts over time. By installing a water hammer arrestor, the impact of the shockwave is mitigated, helping to maintain the integrity of the plumbing and prolonging its lifespan.
Pressure Fluctuations: Fluctuations in water pressure can cause inconsistent dishwasher performance, such as inadequate rinsing or filling issues. A water hammer arrestor stabilizes the water pressure, ensuring that the dishwasher operates efficiently and effectively throughout its cycle.
Potential Damage to Appliances: Continuous exposure to water hammer can lead to significant damage to dishwashers and other appliances connected to the plumbing system. The installation of a water hammer arrestor protects these appliances from the damaging effects of shockwaves, helping to avoid costly repairs or replacements.
