Understanding Water Hammer Arrestors for Dishwashers

Water hammer is a common plumbing issue that occurs when water moving quickly through pipes suddenly stops or changes direction. This sudden change in pressure creates a shock wave, resulting in a loud banging noise — often likened to the sound of a hammer striking metal. While water hammer is generally harmless, it can indicate underlying plumbing issues and may lead to damage over time. One effective solution to mitigate this noise and prevent potential damage is installing water hammer arrestors, especially in appliances such as dishwashers.

What is a Water Hammer Arrestor?

A water hammer arrestor is a device designed to absorb the shock waves produced when water flow is abruptly interrupted. Typically cylindrical in shape, these arrestors contain a piston or diaphragm separated by an air cushion, which acts as a buffer against high-pressure surges in the plumbing system. When water flow is suddenly halted, the movement compresses the air cushion, effectively dampening the force of the pressure wave and eliminating the banging noise associated with water hammer.

Why Install a Water Hammer Arrestor for Your Dishwasher?

1. Noise Reduction One of the primary reasons homeowners consider installing a water hammer arrestor is to reduce disruptive noises. Dishwashers, particularly when filling or draining water, can produce significant vibrations and noise. A water hammer arrestor can significantly diminish these sounds, leading to a quieter kitchen environment.

2. Preventing Damage Over time, repeated instances of water hammer can cause wear and tear on plumbing components, including joints, fittings, and appliances. The high-pressure surges may lead to leaks or even burst pipes. Installing a water hammer arrestor helps safeguard your plumbing system and appliances from the strain of sudden pressure changes.

3. Improved Appliance Lifespan Dishwashers are significant investments in home appliances. By reducing the stress caused by water hammer, you can prolong the lifespan of your dishwasher. Preventative measures, such as the installation of an arrestor, can save homeowners from costly repairs or replacements down the line.

4. Enhanced Water Flow In some cases, water hammer can restrict the flow of water, affecting the efficiency of your dishwasher. A water hammer arrestor helps maintain even water flow, ensuring that your dishwasher operates efficiently and performs its best during cycles.

Installation Considerations

Installing a water hammer arrestor is generally a straightforward process but may require some plumbing knowledge. They can be installed in various places within your plumbing system, such as

- Near the dishwasher’s water supply. - Close to other appliances that may generate water hammer. - At the main water supply line.

A water hammer arrestor can be purchased at most hardware or plumbing supply stores, and a variety of models are available to suit different plumbing systems. When selecting an arrestor, it’s crucial to choose one that matches the pressure and flow characteristics of your home’s plumbing.

For homeowners not comfortable with plumbing tasks, hiring a professional plumber is advisable. They can ensure that the arrestor is installed correctly and provide recommendations on the best placement for maximum effectiveness.

Conclusion

Addressing water hammer issues is essential for maintaining a peaceful and efficient kitchen environment. The installation of a water hammer arrestor for your dishwasher can significantly reduce unwanted noise, protect your plumbing system, and enhance the longevity of your appliances. By taking this proactive step, you can ensure a quieter home and a more efficient dishwasher, allowing you to enjoy the convenience of modern appliances without the nuisance of disruptive sounds. If you suspect you have water hammer issues or want to install a water hammer arrestor, consider consulting with a plumbing professional to assess your needs and explore your options.
