If the shower produces water that’s too hot, even with the temperature turned right down, or if the temperature varies sharply every few seconds, your shower head might be blocked.
- This can happen in hard water areas, where limescale blocks the shower head spray, limiting the amount of water that can flow through the shower.
- With the shower switched off, unscrew the shower head from the hose and leave it for several hours in white vinegar.
- Rinse well and then test to see if the problem has been solved. In extreme cases you may need to replace the shower head.
