No one in the family burst in the middle of the night, and the property was not handled in time, causing water to flow into the elevator. Who will bear the responsibility?

Hello, according to your description, the elevator loss caused by the water pipe leakage in the owner's house should be borne by both the property and the owner.

First of all, the property was not found in time, and the elevator was damaged due to water pipe leakage, and the property should bear part of the responsibility. Secondly, the owner's home water pipe leaks, and the owner has no obligation to repair it, so both parties have the responsibility and need to compensate for this loss.
