No matter who solves the problem of water leakage in the kitchen.

According to what you said, the water running upstairs may be caused by two reasons: First, the poor quality of the house leads to water leakage or the fault of the upstairs owner leads to water running, but whatever the reason, it has nothing to do with the property management company and does not involve the legal relationship between the property management company and the owner. I hope you can understand this.

Second, the poor quality of housing leads to water leakage, which involves the contractual legal relationship between the owner and the developer based on the housing sales contract. The developer shall be liable for breach of contract for the loss of the owner due to the leakage of flue and water pipe in the defective house delivered by the developer. In this regard, you can ask the property to contact the developer to solve your problem.

Third, the upstairs owners' fault leads to water running, which involves the tort legal relationship between the owners based on tort. The fault of the upstairs owner has caused the loss of your downstairs house, which has constituted an infringement on the property rights of the downstairs owner and should be liable for tort compensation. If the property company and the upstairs owner can't communicate, they can file a lawsuit.

I hope this helps you. ...
