Where can I complain about pouring water upstairs?

It is illegal to deliberately pour water at high altitude, and you can call the police. The police will judge whether the other party's behavior constitutes a crime, usually on the basis of endangering public safety.

If water falls from the sky and clothes are lost, you can first keep evidence, such as videos, and then go upstairs to collect personal information and negotiate with the other party to compensate for the loss. If the other party refuses, the neighborhood Committee can be involved, or the property can be involved in negotiation. If negotiation fails, a lawsuit can be brought to the local people's court.
