How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 1 of 5
This guide provides detailed instructions for installing a water hammer arrestor to eliminate the loud banging noises in pipes that occur when water flow is stopped abruptly. The process involves identifying the source of the noise, shutting off the main water supply, cutting into the problematic pipe, and installing a T-fitting with an arrestor to absorb the hydraulic shock.

FAQs
Is this water hammer arrestor installation project suitable for a beginner, and how long will it typically take?
Yes, this project is rated for beginners, but it requires careful attention to detail and confidence in working with plumbing. The estimated time is about 3 hours, but it could take longer if you encounter unexpected pipe configurations, need to drain the system multiple times, or require additional trips for materials.
What are the most critical tools required, and can I substitute any of the specialized items?
A tubing cutter (like the GEARWRENCH Mini Tubing Cutter) and adjustable wrenches are essential for precise cuts and secure, leak-free connections. While a reaming tool is highly recommended for smooth pipe edges, you might be able to carefully deburr with a utility knife if absolutely necessary. Do not skip having a bucket and towels readily available for water drainage.
What safety precautions should I prioritize when cutting into my home's water pipes?
Always ensure the main water supply is completely shut off and pipes are fully drained before making any cuts to prevent flooding. Wear appropriate eye protection to guard against debris or splashing water. Double-check all measurements before cutting to avoid costly errors and ensure a proper fit for your new components.
How do I choose the correct size and type of water hammer arrestor for my specific plumbing issue?
You'll need to match the arrestor's connection size (e.g., 1/2 in. or 3/4 in. MIP) to your existing pipe's diameter where the banging occurs. For high-volume fixtures like washing machines, a larger or dedicated arrestor might be more effective. If unsure, observe where the loudest bang is and measure the pipe at that location.
