How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 6 of 7
In this video
Slide the compression nut and the new ferrule over the end of the flexible pipe. Insert the pipe into the fitting body and slide the nut down to the threads. Hand-tighten the nut as much as possible. Then, using an adjustable wrench, tighten the nut an additional one-half to one full turn to compress the ferrule and create a seal.
Goal: Secure the flexible pipe to the new fitting
- Do not overtighten the compression nut, as this can damage the fitting or crush the pipe.

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.
