Your shower head is leaking
The leakage of the shower head may be due to an improper installation or a defect in the shower head.
1 - Check the fitting of the shower head. Please make sure that both joints are present in the head fitting:
Make sure that joint n°2 is in the right direction.
2 - If the construction is correct, and the shower head still leaks, it is faulty and a replacement is necessary.
