Step 6 · Install the New Shower Arm
First, slide the new decorative flange (escutcheon) onto the long end of the new shower arm, ensuring its finished side faces away from the wall threads. Now, carefully insert the taped end of the arm into the fitting in the wall. Hand-tighten the arm by turning it clockwise until it is snug. Continue turning until it is pointing downwards at the correct angle. If you cannot get it tight enough by hand, use a rag-wrapped wrench on the straight part of the pipe for one final, gentle turn. Stop when it feels snug; do not overtighten. Slide the flange flush against the wall.
