Possible causes: 1) Excessive water pressure in the pipes. 2) Sudden faucet closure causing the water hammer effect. 3) Vibration due to insecurely fixed pipes. 

Solutions: 1) Close the faucet gently to reduce the impact of water flow. 2) Install a pressure relief or water hammer eliminator. 3) Reinforce loose pipe brackets.

1) Soak the shower head in white vinegar once a month to prevent scale.

2) Check the rubber rings and hoses every six months, and promptly replace aging components. 

3) Choose a pure copper/stainless steel shower to extend service life. 

4) If the problem cannot be resolved on your own, contact FAENZA's professional maintenance personnel or after-sales service to avoid improper operations exacerbating the problem.
