Once you've cleaned the threads of old debris, you should wrap the threads in Teflon tape to prevent leakage when the new shower head is installed.
- Take about 9-12 inches of Teflon tape and wrap it around the threads in a CLOCKWISE direction for several turns (4-5).
- Don't extend above the threaded area or else the tape will show when the new head is installed.
- Take your fingers and gently press the tape into the threads.
