How to Install an Air Chamber to Prevent Water Hammer · Step 2 of 7
In this video
Locate the main water shut-off valve for your house, often found behind an access panel. Turn the lever so it is perpendicular to the pipe to cut off the water flow. Go to a sink and open the faucet to drain any remaining water from the pipes. Before working in the tub, close the drain or cover it with a towel to prevent any small parts from being lost.
Goal: Plumbing Pipes Repair
- Ensure the water is completely off by checking a faucet. Failure to do so can result in significant water damage.
- Covering the drain is a simple step that can save you from the major headache of retrieving a lost part.

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.
