How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 5 of 5
In this video
First, turn off the hot and cold water supply valves leading to the washing machine. Then, disconnect the old hoses. Carefully examine the entire length of each rubber hose for any signs of cracking, bulging, or splitting. Squeeze the hoses to feel for weak or thin spots. Pay close attention to the fittings at both the wall valve and the back of the machine, as this is where ruptures often occur. Also, check that the rubber washers inside the fittings are not brittle and still provide a good seal.
Goal: Identify Wear and Tear
- Any signs of cracking, bulging, or splitting mean the hoses are worn out and need immediate replacement.

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.
