A water hammer arrestor is an essential plumbing device used to prevent the impact of water hammer, a phenomenon that can cause damage to pipes and appliances in a plumbing system. Water hammer occurs when the flow of water in the pipes is suddenly stopped or redirected, creating a shockwave that can lead to banging or rattling noises. This can be particularly damaging to appliances like dishwashers, which rely on a steady flow of water for optimal performance. In this article, we will explore how a water hammer arrestor can extend the life of a dishwasher and why it is a valuable addition to any plumbing system.
Understanding Water Hammer
Before delving into the benefits of a water hammer arrestor, it is crucial to understand what water hammer is and how it can adversely affect dishwashers. Water hammer occurs when the flow of water in the pipes is interrupted suddenly, leading to a surge of pressure that reverberates throughout the plumbing system. This fluctuation in pressure can cause pipes to rattle, shake, or even burst, causing potential damage, leaks, or a complete breakdown of the system.
Impact on Dishwashers
Dishwashers rely on a consistent flow of water to efficiently clean dishes. When water hammer occurs, the sudden surge of pressure can disrupt the flow of water to the dishwasher, causing it to malfunction or work inefficiently. The constant shocks and vibrations caused by the impact of water hammer can also lead to damages such as loosening of fittings, leakage, or even cracks in the dishwasher’s internal components.
How a Water Hammer Arrestor Works
A water hammer arrestor is designed to absorb the shockwave generated by water hammer, thus protecting the integrity of the plumbing system and the appliances connected to it. It consists of a sealed chamber that contains compressed air or gas, acting as a cushion to absorb the sudden pressure surge. When a sudden change in water flow occurs, the shockwave is absorbed by the air or gas inside the chamber, preventing it from damaging the pipes or the connected appliances.
Benefits of Using a Water Hammer Arrestor with a Dishwasher
1. Reduces Stress on the Dishwasher
By preventing water hammer, a water hammer arrestor significantly reduces the stress and impact on the dishwasher. This helps in minimizing wear and tear on the dishwasher’s components, increasing its longevity and overall lifespan.
2. Minimizes Noise and Vibrations
Water hammer can result in loud, banging noises and vibrations within the plumbing system. By installing a water hammer arrestor, these noises and vibrations are effectively eliminated, resulting in a quieter and more peaceful environment during dishwasher operation.
3. Prevents Damage to Plumbing System
Water hammer can lead to significant damage to the plumbing system, including burst pipes, leaks, or water supply interruptions. A water hammer arrestor acts as a safety net, preventing these issues from occurring and preserving the overall integrity and functionality of the plumbing system.
4. Enhances Dishwasher Performance
By ensuring a steady and uninterrupted flow of water, a water hammer arrestor helps maintain consistent water pressure, resulting in improved dishwasher performance. This translates to cleaner dishes, reduced water consumption, and energy efficiency.
Installation and Maintenance
Installing a water hammer arrestor for a dishwasher involves identifying the appropriate location in the plumbing system and selecting the right-sized arrestor based on the water flow rate and pipe diameter. It is recommended to consult a professional plumber for installation to ensure accurate placement and functionality.
Water hammer arrestors typically require minimal maintenance. However, periodic checks for leaks or signs of wear and tear are advised. It is recommended to flush the arrestor yearly to remove any sediment or debris buildup that may affect its performance.
In summary, a water hammer arrestor serves as an indispensable device to protect dishwashers and the entire plumbing system from the damaging effects of water hammer. By absorbing the shockwave generated by sudden changes in water flow, it minimizes stress, noise, and vibrations, while enhancing dishwasher performance and prolonging its lifespan. Installing a water hammer arrestor is a wise investment to ensure the smooth operation and longevity of your dishwasher while safeguarding your plumbing system from potential damage.
