Understanding Water Hammer Arrestors for Dishwashers

Water hammer is a common plumbing issue that can lead to loud banging noises in your pipes, often described as a slamming sound when a faucet or appliance shuts off suddenly. This phenomenon occurs when a fluid in motion is forced to stop or change direction quickly, causing shock waves to travel through the water pipes. If you've ever experienced this startling noise when using your dishwasher, you might be considering the installation of a water hammer arrestor.

What is a Water Hammer Arrestor?

A water hammer arrestor is a device designed to absorb the shock wave created when water flow is abruptly stopped. It consists of a sealed chamber that contains air or gas, which acts as a cushion to dampen the pressure spike traveling through the pipes. By equalizing the pressure changes, water hammer arrestors help eliminate those disruptive noises and protect your plumbing system from potential damage.

How Does it Work?

When water is forced through a pipe and suddenly halted, the momentum travels back through the system, resulting in pressure surges that cause the banging sound. A water hammer arrestor prevents this by allowing the shock wave to compress the air in the chamber. As the water flows, it pushes against the air-filled chamber, absorbing the shock and reducing the intensity of the pressure spike. This process not only quiets the disruptive sounds but also helps minimize wear and tear on the plumbing system.

Why Install a Water Hammer Arrestor for Your Dishwasher?

Installing a water hammer arrestor for your dishwasher can be particularly beneficial for several reasons. Firstly, dishwashers often use solenoid valves that turn the water flow on and off abruptly. This can create significant pressure surges in your plumbing system, leading to water hammer. A water hammer arrestor will mitigate this issue, providing a quieter and smoother operation of your dishwasher.

Moreover, water hammer can cause long-term damage to your plumbing system. Over time, the repeated pressure surges can weaken pipes and fittings, leading to leaks or even bursts. By installing a water hammer arrestor, you can prolong the lifespan of your plumbing, reducing the need for costly repairs.

Installation Considerations

Installing a water hammer arrestor is usually a straightforward process, but it may require the assistance of a professional plumber, particularly if you are not experienced with plumbing systems. The device should be placed close to the affected appliance—in this case, the dishwasher—to ensure effective absorption of the shock waves.

When selecting a water hammer arrestor, it’s important to choose one that is appropriately sized for your plumbing system. Arrestors come in various sizes and types, so consulting with a plumbing professional can help you determine the best option for your specific needs.

Conclusion

In summary, if you're noticing loud bangs or thumps while using your dishwasher, a water hammer arrestor might be the solution you need. This simple yet effective device can significantly reduce the noise associated with water hammer, enhance the performance of your plumbing system, and protect against potential damage. By investing in a water hammer arrestor, you not only enjoy a quieter kitchen but also contribute to the longevity of your plumbing infrastructure. If you haven't yet considered installing one, now is the time to explore your options and consult with a plumbing professional.
