Most likely cause & what to check
Limescale build-up in the shower head nozzles is the most common cause of uneven or weak spray.
Remove the shower head by unscrewing it from the hose (turn anti-clockwise).
Soak the shower head in a bowl of white vinegar overnight, or use a proprietary descaler for 30–60 minutes.
Use an old toothbrush to scrub the nozzles — they should poke out freely when clean.
Rinse thoroughly and refit. Run the shower briefly before using to flush any residue.
If the shower head is heavily corroded or the nozzles are permanently blocked, replacement heads are inexpensive.
