Step 5 · Attach the Shower Arm Diverter
Take the shower arm diverter from your kit. Identify the female threaded connection, which is typically at the back or top of the diverter. Align it with the freshly taped shower arm threads and begin screwing it on clockwise by hand. Tighten it until it is snug and pointing in the correct orientation (the fixed head outlet facing forward, the hose outlet facing down). If you cannot get it tight enough by hand, use your adjustable wrench with a soft cloth to give it a final quarter-turn. Be very careful not to overtighten and crack the diverter body.
