Quick answer. Unscrew the old head by hand or with a cloth-wrapped wrench, clean the threads, wrap PTFE tape, screw the new one on.
The leak is usually at the threads, not a 'bad' new head.
MarketPalace Guide Center writes this as a solution walkthrough — the order we would use if we were in the room with you. We name the next click, then what to do if that click fails. We do not sell the TV, the kettle, or the plane ticket.
If a menu name on your set or phone does not match, use the closest wording and email hello@marketpalace.shop. We correct live pages when the path has moved.
What you need
- PTFE / plumber's tape
- Cloth
- Adjustable wrench
In this guide
1. Unscrew the old head
Protect the chrome with a cloth if you need a wrench.
2. Clean old tape off the shower arm threads
A bit of vinegar helps if they are crusted.
3. Wrap PTFE tape clockwise 3–4 turns
Clockwise as you look at the open end.
4. Screw the new head on hand-tight plus a small snug
Do not crush the fitting. Test for drips.
If it still fails
- If the arm itself spins in the wall, stop — that is a different repair.
When you are done, browse more in Home & Fixes or search the Guide Center for the next job on your list. A neighbour problem — a remote, a bill, a suitcase — has its own walkthrough.
