My family's life is affected by the private reform of the upstairs water, and the property is not as it is. Is it legal to take the property?

The upstairs owner bears the main responsibility, and the property has the responsibility of supervision, guidance, communication and coordination.

The installation and renovation of water pipes must conform to the relevant decoration requirements and standards. If it is violated, the property should not be approved, so the property has the responsibility of supervision and guidance. If there is a problem because of decoration, the property also has the responsibility and obligation to coordinate among the owners and be responsible for communication and coordination.

As you said, the upstairs owner's water-changing pipeline violates the national standards for residential design, and the property has the supervisory responsibility when reviewing the upstairs owner's decoration; At the same time, the water leakage upstairs affects your home, and the upstairs violates the property law. You asked the question that the property should actively coordinate with the upstairs owners, but the property is always delayed, so the property has the responsibility of coordination.

So when you sue the upstairs owner, you can also sue the property for inaction. Of course, the evidence of regulatory responsibility is easy to find, and the evidence of coordinating responsibility may be difficult to do.
