Remove Old Shower Arm — Clean Threads and Flush Pipe
Part of project
How to Replace a Shower Head and Shower Arm · Step 4 of 8
In this video
Begin by removing your existing showerhead from the old shower arm. Then, carefully unscrew the old shower arm from the fitting inside the wall by turning it counter-clockwise. Use a wrench with a rag wrapped around the pipe to prevent scratching the finish. If the arm is stuck due to corrosion or mineral buildup, apply a penetrating oil like WD-40 to the threads inside the wall and let it sit for a while before trying again. Be cautious, as old, corroded threads can sometimes break off inside the wall fitting, which would complicate the repair.
Goal: Remove the existing shower arm to prepare for the extender installation.
- Be very careful when unscrewing the original shower pipe. A lot of times the threads can break off inside the wall fitting, which are reasonably hard to get out.
- To help loosen a stuck pipe, spray some penetrating oil like WD-40 into the fitting and let it work for a bit before attempting to unscrew it.

FAQs
What tools are absolutely essential for this project, and can I substitute any of them?
You'll definitely need an adjustable wrench to loosen and tighten the shower arm and head. While specific pliers like Channellock are recommended for better grip, an adjustable wrench is usually sufficient for most connections. Always have a rag or towel ready for any drips or residual water in the pipes.
How can I prevent leaks after installing the new shower head and arm?
The key to preventing leaks is the proper application of Teflon tape. Wrap 3-5 layers of tape clockwise around the threads of both the shower arm and the shower head, ensuring it's snug. Also, make sure to clean the existing pipe threads thoroughly before installation to create the best possible seal.
My old shower arm is incredibly stuck. What's the safest way to remove it without damaging my plumbing?
If your old shower arm is stuck, try applying a penetrating oil around the threads and let it sit for a few minutes. Use your adjustable wrench to apply firm, counter-clockwise pressure, being careful not to twist the pipe inside the wall. If it still won't budge, consider calling a professional to avoid causing serious damage to your plumbing.
Do I need to turn off the main water supply to my house, or is there a specific shut-off for just the shower?
Yes, you must turn off the main water supply to your house for this project, as individual showers typically don't have separate shut-off valves. After turning off the main supply, open the shower faucet to drain any remaining water from the pipes before you begin removing components. This prevents unexpected sprays and water damage.
