FAQs
What should I do if my old shower arm is stuck and won't unscrew easily?
If the old shower arm is stubborn, try applying some penetrating oil around the threads and letting it sit for a few minutes. Use your pipe wrench with firm, steady counter-clockwise pressure. You might need a longer handle or cheater bar for added leverage, but be careful not to overtighten and damage the in-wall fitting.
How can I prevent leaks after installing the new shower arm?
The most crucial step is properly applying thread sealant. Wrap 3-5 layers of Blue Monster PTFE Thread Seal Tape clockwise around the new shower arm's threaded end before screwing it in. Ensure the female threads inside the wall fitting are thoroughly cleaned of old tape or debris with a wire brush or pick tool for a tight seal.
What's the most important safety precaution I need to take before starting this project?
Always turn off the main water supply to your house or at least the specific bathroom before beginning any work. This prevents accidental flooding and allows you to work safely without water pressure. Double-check that the water is off by turning on another faucet nearby.
How long should this project take for a beginner, and what's the typical cost saving compared to hiring a plumber?
For a beginner, this project typically takes 30-60 minutes, assuming you have all the tools and materials ready. Doing it yourself can save you significantly, as plumber call-out fees and labor for such a simple job can range from $100-$300, while materials often cost under $50.
