In this video
Turn on the shower water and carefully inspect all the connections you made for any signs of leaking or dripping water. Check the connection at the shower arm, the extension arm, and the showerhead itself. If there are no leaks, the installation is complete. If you spot a leak, turn off the water and tighten the connection slightly or re-apply the thread seal tape.
Goal: Verify Installation
- If a leak persists, you may need to add more thread seal tape or check that the rubber washer is seated correctly.

FAQs
What should I do if the old shower arm is stuck and won't unscrew?
If your old shower arm is stubborn, apply a generous amount of penetrating oil (like Blaster 11 oz. PB Penetrating Oil) to the threads where it meets the wall. Let it sit for 15-30 minutes to work its magic. Then, use your adjustable wrench to try again, applying steady pressure. If it's still stuck, a longer handled wrench might give you more leverage, but be careful not to damage the wall.
How much Teflon tape do I need to use to prevent leaks effectively?
For a watertight seal, wrap the threads of the new shower arm with Teflon tape 3 to 5 times in a clockwise direction. Ensure the tape covers all the threads and is applied snugly. Wrapping in the direction of tightening helps prevent the tape from unraveling as you screw the arm in.
Is it absolutely necessary to turn off the water for this simple replacement?
Yes, turning off the water supply to your shower, or the entire house if there's no individual shut-off, is crucial. This prevents water from gushing out when you remove the old arm, ensures a dry workspace, and avoids potential leaks or water damage during the installation process. It's a key safety and preventative step.
What's the most common mistake a beginner makes when replacing a shower arm?
The most common mistake is cross-threading the new shower arm into the wall fitting. Always start screwing the new arm in by hand to ensure it's aligned correctly before using a wrench. Another frequent error is not applying enough (or any) Teflon tape, which leads to immediate leaks after installation.
