The sewer pipe of the owner's house in the community is rotten. Is it property maintenance?

Fifty-second water supply, power supply, gas supply, heating, communications, cable television and other units shall bear the responsibility for the maintenance and conservation of related pipelines and facilities in the property management area according to law.

If the units specified in the preceding paragraph temporarily occupy or dig roads and sites due to maintenance, they shall promptly restore the original state.

According to the Property Management Regulations, the water supply department is responsible for the maintenance of broken water pipes.

Of course, it depends on whether there is an agreement in the contract signed by the owners' Committee and the property in your community.
