No matter what happens when the kitchen sewer leaks into the downstairs property.

Legal analysis: Need specific analysis. For example, a water leakage accident upstairs can generally be solved by the following methods: First, if the water leakage is caused by the house quality failing to meet the national standards after appraisal, the damaged owner can ask the developer to repair the water leakage of the house during the warranty period and compensate the owner for the losses caused thereby. The construction unit shall undertake the property warranty responsibility in accordance with the warranty period and scope stipulated by the state. Under normal use conditions, the anti-leakage warranty period of bathrooms, kitchens and external walls with waterproof requirements is not less than 8 years. Second, if the upstairs owner does leak water from the downstairs owner due to the decoration or laying of water pipes, the upstairs residents should promptly find out the cause of the leakage and carry out maintenance, and should also be responsible for the damage caused by their misconduct to the downstairs residents.

Legal basis: Article 20 of the Measures for the Administration of Special Maintenance Funds for Residential Buildings, the maintenance, renovation and renovation costs of residential buildings and facilities and equipment shall be shared according to the following provisions: (1) The maintenance, renovation and renovation costs of residential buildings or commercial buildings and non-residential buildings shall be shared by the relevant owners according to the proportion of their respective property construction areas.
