Symptoms
- Head moves or droops on its own during use
- Spray direction drifts while showering
- Slight leaking at the loose joint
- Head feels floppy when touched
Likely causes
- CommonLoose connection at the shower arm threadsThe head simply isn't screwed on tightly enough to hold its position under water pressure.
- CommonWorn ball-joint mechanism (adjustable heads)Heads with a swiveling ball joint can loosen with repeated adjustment over time.
- PossibleStripped threads on the shower armMetal or plastic threads can wear down after years of attaching and removing heads.
- Less commonLoose shower arm itself within the wall fittingThe arm connecting to the wall pipe can work loose from the wall elbow fitting.
What to do
- Try tightening the head by hand first, turning clockwise while holding the arm steady.
- If it's still loose, wrap the arm threads in cloth and use a wrench for a firmer connection without overtightening.
- Check for a tightening ring or thumbscrew at the ball-joint if your head is adjustable, and snug it down.
- If threads look stripped or worn, remove the head and inspect closely with a flashlight.
- Wrap fresh plumber's tape around the arm threads for a better grip if the fit still feels loose.
- If the arm itself wiggles within the wall, that connection may need to be resealed or tightened from inside the wall, which is more involved.
- Test by running water and gently pushing the head to confirm it now holds position.

When to call a pro
Call a plumber if the shower arm itself is loose within the wall, since that connection is harder to access and reseal.
