1. It is very likely that after use, there is still a certain amount of water inside the shower. Due to the action of atmospheric pressure, it will be difficult for the water inside to flow out. After being closed for a period of time, the shower will be slightly affected by the outside world. The pressure is out of balance, air enters the shower pan, and the rest of the water comes out. This is a common problem with large overhead showers.
2. There is a problem with the quality of the shower itself, such as water leakage or damage. In this case, it is recommended to check the shower. If there is continuous water leakage, it proves to be a quality problem, and it is recommended to repair or buy it.
