If water leakage occurs upstairs, the status of water seepage downstairs should first be determined.

Prove that you did not damage it artificially. If this is the case, then you should solve the problem yourself.

Find out that the neighbor is responsible for causing the leakage upstairs. In order to clarify the situation, the damaged owner can ask the housing quality inspection department to identify the cause of the leak and how to repair it.

Check to see if the house is still within the warranty period, because generally the waterproof warranty of a newly purchased house is 5 years and the pipe warranty is 2 years. If the house leaks, which is not man-made and is still within the warranty period, the developer must bear the corresponding responsibility. Of course, if you live on the top floor and a water leak occurs upstairs, the developer or property company must repair it, and the cost will also be borne by the other party
