Who is responsible for maintaining indoor underground water pipes?

Legal analysis: If the house is still under warranty and the sewer leaks at home, the property management company can assist and find the developer for maintenance. If it is a public sewer after the two-year warranty period, the property management company can undertake the maintenance responsibility and the maintenance fund can also be used for public facilities. If the sewer leaks because of improper home decoration or personal use, the responsibility is entirely personal, and the owner himself needs to bear the maintenance responsibility. If it is the loss caused by the owner downstairs, he should also compensate.
