How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 1 of 7
In this video
Before starting any work, prepare the area under the sink. Begin by shutting off the hot and cold water supply valves, typically by turning them clockwise. Place a bucket or container underneath the plumbing to catch any water that will drain from the lines. Open the existing faucet to release any pressure and drain the remaining water. Finally, use an adjustable wrench to disconnect the hot and cold water supply lines from the shutoff valves.
Goal: Shut off water and disconnect supply lines
- If you cannot find or operate the shutoff valves under the sink, you will need to shut off the main water valve for the entire house.
- Keep a towel handy to clean up any spills immediately.

FAQs
Do I really need all the listed tools for this water hammer arrestor installation, or can I manage with fewer?
For a successful and leak-free installation, the tubing cutter, deburring tool, and adjustable wrenches are essential. While you might try a hacksaw, a tubing cutter ensures a cleaner, square cut vital for compression fittings. The deburring tool prevents damage to the O-ring and ensures a tight seal, so these are not optional for a reliable outcome.
What are the critical safety precautions I must take when installing a water hammer arrestor, especially as a beginner working with plumbing?
Always begin by shutting off the main water supply to your home and draining the lines to prevent unexpected floods or sprays. Wear safety glasses to protect against debris and gloves to prevent cuts from sharp pipe edges. Double-check that the water is completely off before making any cuts to the pipe.
How much time should a beginner budget for this water hammer arrestor installation, and what's the approximate material cost?
A beginner should typically budget 1 to 2 hours for this project, allowing time for preparation, precise cutting, assembly, and thorough leak checks. The primary material cost will be for the water hammer arrestor itself and the compression tee, generally ranging from $30-$60 depending on your specific chosen parts and local pricing.
What are the most common mistakes beginners make when installing a water hammer arrestor, and how can I avoid them?
A frequent mistake is not deburring the pipe ends thoroughly, which can lead to leaks at the compression fitting due to an improper seal. Another common error is under-tightening the compression nuts; ensure they are snug and firm, but avoid overtightening and stripping the threads. Also, remember to use Teflon tape on the arrestor's threaded connection points, but not on the compression connections themselves.
