A water hammer arrestor is designed to prevent or minimize the "water hammer" effect, which occurs when there is a sudden change in water flow direction in the plumbing system. This can happen when a valve is quickly closed, causing the water to slam against the pipes, creating a loud noise and potential stress on the pipes and fittings.
Whether or not you should install a water hammer arrestor for your new LG washer depends on a few factors:
Existing Water Hammer Issues: If you've been experiencing water hammer issues with your previous washer or other appliances in your home, it may be beneficial to install a water hammer arrestor. Water hammer can lead to long-term damage to plumbing components, and the arrestor can help mitigate this problem.
Manufacturer Recommendations: Check the user manual or documentation that came with your LG washer. Some washing machine manufacturers recommend using a water hammer arrestor as a precautionary measure to protect their appliances and ensure smooth operation.
Local Plumbing Codes: Some building codes or regulations might require the use of water hammer arrestors for specific appliances or plumbing configurations. It's a good idea to check with your local plumbing authority to see if there are any specific requirements for your area.
Noise and Vibration: If the washer causes noticeable noise or vibration during use, even if it's not necessarily water hammer-related, a water hammer arrestor could help reduce these effects by absorbing pressure fluctuations.
Personal Preference: If you're particularly concerned about potential water hammer issues or want to take preventive measures to protect your plumbing system, installing a water hammer arrestor could provide peace of mind.
If you decide to install a water hammer arrestor, you can either hire a plumber to do the job or install a water hammer arrestor yourself if you have the necessary plumbing skills and tools. The installation process typically involves turning off the water supply, cutting the water line, and attaching the arrestor between the cut ends. It's essential to install the arrestor correctly and at the appropriate location to be effective.
Ultimately, the decision to install a water hammer arrestor is up to you and depends on your specific circumstances and preferences. If you're unsure about the necessity of the arrestor or the installation process, consulting with a licensed plumber can help you make an informed decision and ensure the correct installation if you choose to proceed.
