How to Install an Air Chamber to Prevent Water Hammer · Step 2 of 7
In this video
First, locate the main water shut-off valve for your house and turn it off completely. The valve's location can vary, but it's often located outside near the water meter or inside in a basement or utility closet. In the video, the valve is in an access pipe in the yard.
Goal: Plumbing Pipes Repair (Repairing damaged or leaking plumbing pipes.)
- Confirm the water is off by turning on a faucet elsewhere in the house. If water still flows, you have not shut off the main valve.

FAQs
How difficult is this project for a beginner, and is the 4-hour estimate accurate?
This project is rated beginner-friendly, but taking your time, especially with pipe cutting and compression fittings, is crucial. The 4-hour estimate accounts for preparation, potential draining time, and careful installation, so allow yourself ample time to avoid rushing and ensure a leak-free result.
What are the most common mistakes when using compression fittings, and how can I prevent leaks?
Leaks from compression fittings often stem from not deburring pipe ends properly, misaligning the nut, or over-tightening. Ensure pipe ends are smooth and square, hand-tighten the nut, then use a wrench for another 1/2 to 3/4 turn for a secure seal, being careful not to overtighten and strip the threads.
The guide lists multiple copper pipe cutters; which one is best for this project, and is a deburring tool essential?
A close-quarters tubing cutter or an AUTOCUT 1/2 in. cutter is ideal for working in tight spaces common under sinks or behind walls. Yes, a deburring tool like the Husky 1-5/8 in. reamer is absolutely essential to ensure a smooth, clean pipe end for leak-free compression fitting connections.
What are the most important safety precautions to take during this water hammer arrestor installation?
Always shut off the main water supply and drain the lines completely before cutting. Wear safety glasses to protect your eyes from metal shavings, and be cautious of sharp pipe edges after cutting. Have towels and a bucket ready for any residual water to minimize mess.
