Step 6 · Prepare and Install the New Shower Arm
Take your new shower arm and slide the new escutcheon (flange) onto the end that will go into the wall. Now, take your roll of Teflon tape. Holding the threaded end of the shower arm, wrap the tape clockwise around the threads 3 to 4 times. Wrapping clockwise ensures the tape tightens as you screw the arm in, rather than unraveling. The tape should be snug and conform to the threads. Now, insert the threaded end into the wall fitting and begin turning it clockwise by hand. Continue to hand-tighten until it is snug and pointing in the correct downward direction. If it's not tight enough when it's properly aligned, give it one more full turn with your pliers (using a rag to protect the finish). Do not overtighten. Slide the escutcheon flush against the wall.
