In this video
Take a wire brush and thoroughly scrub the male threads of the pipe extending from the wall. This removes any old sealant, rust, or debris. After cleaning, take a roll of thread seal tape (Teflon tape) and wrap it tightly around the threads 3-4 times in a clockwise direction.
Goal: Plumbing Pipes Repair (Leaking)
- Wrapping the tape clockwise prevents it from bunching up or unraveling when you screw on the new faucet.

FAQs
How long does it typically take to replace a shower arm, and what's the estimated cost for materials?
For a beginner, this project usually takes about 30-60 minutes, assuming no major complications like a stuck old arm. The cost primarily depends on your chosen new shower arm and shower head, ranging from $20-$100+ for materials, making it a very cost-effective DIY upgrade.
What are the most crucial tools and materials I need to ensure a successful, leak-free installation?
Beyond your new shower arm and head, essential tools include an adjustable wrench for tightening and a wire brush for cleaning old threads. Plumber's tape (Teflon tape) is critical for sealing the new arm's threads; don't skip it. Have rags ready for any drips.
Are there any important safety precautions I should take before starting, especially since it involves plumbing?
Absolutely. Always turn off the main water supply to your house or at least to the bathroom before starting to prevent accidental flooding. Also, protect your shower/tub surface from dropped tools or materials using a cloth or old towel.
My old shower arm is really stuck. What's the best way to remove it without damaging the wall fitting?
If your old shower arm is stuck, try applying some penetrating oil around the threads and letting it sit for a few minutes before trying again with an adjustable wrench. Turn counter-clockwise with steady, firm pressure. Be careful not to apply excessive force that could twist the pipe inside the wall, which would require professional help.
