The rainwater pipe outside the building is broken and does not belong to the property.

Legal analysis: Whether the property management company should bear the responsibility of compensation for maintenance caused by the loss of rainwater pipes outside the building needs to be comprehensively considered in combination with the following specific circumstances:

1. Rainwater pipes fall off due to man-made damage, and the property management company shall not be liable for maintenance and compensation. It shall be borne by the actor who caused the rain pipe to fall off, and be responsible for the maintenance and compensation of related losses caused by household leakage.

2. The property management company shall not be liable for maintenance and compensation for non-man-made damage, but the house is within the quality warranty period of the construction project. The responsibility for maintenance and compensation shall be borne by the residential construction unit (developer), and the developer may claim compensation from the construction unit.

3, non-man-made damage and beyond the warranty period of residential construction projects, property management use the housing maintenance funds paid by the owners to repair the fallen water pipes, and compensate for the losses caused thereby.
