How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 5 of 5
In this video
Slowly turn the hot and cold water supply valves back on. Carefully inspect all four connection points for any signs of dripping or leaking water. Once you have confirmed there are no leaks, you can plug the washing machine's power cord back into the electrical outlet. Finally, carefully slide the washing machine back into place.
Goal: Turn on water, check for leaks, and finalize installation
- Turn the water on slowly to allow the pressure to build gradually, which can help prevent leaks from sudden pressure shocks.
- It is critical to check for leaks immediately after turning the water on. Check again after a few minutes to be sure.

FAQs
Why do my washing machine pipes bang, and how do these arrestors help?
Washing machines often cause "water hammer" because their solenoid valves close very quickly, creating a sudden pressure surge in the water lines. Water hammer arrestors absorb this shock wave, preventing pipes from banging, vibrating, and potentially damaging your plumbing system over time.
What specific tools and materials are essential for installing these screw-on arrestors?
You will primarily need two adjustable wrenches or groove joint pliers (e.g., Husky 12 in. Adjustable Wrench, Channellock 12 in. Tongue and Groove Slip Joint Pliers) to properly tighten the connections. PTFE thread seal tape (plumber's tape) is crucial for preventing leaks, and a bucket and towels will be useful for catching any drips.
Is this a difficult project for someone new to DIY, and how much time should I set aside?
This is considered a beginner-level plumbing project, making it very approachable for DIY novices. The actual installation of the arrestors is quick, but accounting for water shut-off, hose disconnection, installation, and thorough leak testing, allow approximately 1 to 2 hours to complete the task.
What are the most important safety precautions to take during this installation?
Always shut off the water supply to the washing machine (or the main house supply) before starting to prevent flooding. Have a bucket and towels handy for any residual water. Be careful not to overtighten connections, as this can strip threads or crack fittings, potentially leading to leaks.
