Step 5 · Prepare and Wrap the New Shower Arm

Take your new shower arm and identify the shorter threaded end that will go into the wall. Take the plumber's tape (Teflon tape) and wrap it tightly around these threads. You must wrap the tape in a clockwise direction (the same direction you will turn the arm to tighten it). This prevents the tape from unravelling during installation. Apply 3 to 5 full wraps of tape, ensuring the threads are covered but the opening of the pipe is not blocked. Smooth the tape down with your finger.
