Using this shower arm is a breeze. First, make sure your shower wall has the right 1/2'-14NPT connection. Then, simply screw the shower arm onto it. You can then attach your favorite showerhead to the end of the arm. When it comes to maintenance, just wipe it down with a soft, damp cloth regularly to keep it looking shiny. Avoid using abrasive cleaners as they can scratch the metal surface. Also, check the connections every few months to ensure they're tight and there are no leaks. If you notice any issues, tighten the connections gently with a wrench.
