How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 3 of 5
In this video
Using a pipe cutter, cut out the section of the copper pipe that was punctured by the saddle valve. This ensures the weak point is eliminated. The video then shows soldering in a new copper T-fitting with a proper ball valve attached.
Goal: Plumbing Pipes Installation
- Soldering involves an open flame. Use a heat shield and have a fire extinguisher nearby. Ensure the area is clear of flammable materials.
- Thoroughly clean and apply flux to all copper surfaces before soldering to ensure a strong joint.
- After soldering, use a wet rag to quickly cool the joint and clean off any excess flux.

FAQs
How do I accurately identify the source of water hammer before installing the arrestor?
Listen carefully for the banging sound when a specific faucet, toilet, or appliance (like a washing machine) shuts off abruptly. You can also try gently touching the water lines near suspect fixtures to feel for vibrations when the noise occurs. Installing the arrestor as close as possible to the identified source will yield the best results.
What crucial safety steps must I take before cutting into the water line?
Always turn off the main water supply to your entire home first. Then, open the lowest faucet in your house (e.g., in a basement or outdoor spigot) and the highest faucet to completely drain the water from the pipes. This prevents unexpected water leaks and potential injury while you work.
Do I need special tools to cut copper pipes, and how do I ensure a leak-free connection?
Yes, a copper pipe tubing cutter (e.g., AUTOCUT 1/2 in.) is essential for a clean, straight cut. After cutting, use a reamer and deburring tool (like the Husky 1-5/8 in.) to smooth the pipe's interior and exterior edges. This deburring step is critical for proper sealing and preventing leaks, especially with push-to-connect fittings.
What's the best way to prevent leaks when installing the tee fitting and water hammer arrestor?
Ensure the pipe ends are perfectly clean, smooth, and free of scratches or burrs. Use a depth gauge (like the Tectite Depth Gauge) to mark the correct insertion depth on the pipe for push-to-connect fittings, ensuring it's fully seated. For the arrestor's threaded connection, apply several wraps of PTFE plumber's tape (Harvey 1/2 in. x 260 in.) clockwise to the male threads before tightening.
