Legal subjectivity:

1. First, the cause of the leakage should be identified. If the quality of the new house is not up to standard, the developer will be responsible for repairs during the warranty period; 2. If it is upstairs If it is caused by faults such as improper decoration, the upstairs will be responsible for repairs; 3. If the warranty period of the house has expired, it belongs to the public fee of the whole building. For example, if the main sewer pipe maintenance problem needs to be repaired, the house fee will be charged. If the maintenance fund is **, the property department shall apply for the use of the maintenance fund; 4. If the public ** maintenance fund is not collected, the ** portion shall be borne by all homeowners ** jointly; 5. If it is upstairs If there is a problem with the exclusive part, according to the principle of fairness, the cost will still be borne by the person upstairs. If a lawsuit is filed, a corresponding appraisal may be required to determine the cause of the leak and the amount of the loss. Pay attention to keeping the "Housing Quality Guarantee", payment receipts for the housing company's maintenance fund and other evidence. Legal objectivity:
