I believe many people have experienced the problem of sewer blockage. This situation is worrying, so who is responsible for the blockage of the main sewer? Is it necessary to clean the pipes? How to clean the pipeline? Today, Bian Xiao will explain these issues one by one.

Who is responsible for the blockage of the main sewer?

China property management institute stipulates that the property needs to manage and maintain the * * * used parts and facilities, and the main sewer network is a public * * * pipe network, which belongs to the daily maintenance and repair scope of the property. It is stipulated that the rainwater and sewage pipes of the property should be dredged at least once a year. If the main sewer pipe is blocked because the property fails to dredge the sewer well regularly and does not carry out preventive inspection on the sewer, the property needs to take full responsibility. But if the congestion is caused by littering by the upstairs residents, then the upstairs residents should also be responsible.

Pipeline cleaning method

Pipeline cleaning is to restore the interior of the pipeline to the original surface of the material. The cleaned pipeline can effectively prevent the development of dirt, protect the equipment and effectively prolong the service life of the equipment. There are several cleaning methods for pipelines:

1, chemical cleaning

Chemicals are used to clean pipelines, mainly temporary pipelines and circulating pumping stations. This technology is flexible, fast and thorough.

2, high pressure water cleaning

The high-pressure water jet above 50Mpa is used to peel and clean the inside of the pipeline, which is suitable for short-distance pipelines with a diameter of more than 50cm, with high speed and low cost.

Editor's summary: From the above, we all know that the main sewer pipe is blocked normally and the property is responsible, but sometimes it is annoying to repeatedly urge the property not to respond. At this time, you can also check the cause of the blockage of the sewer pipe. If you don't need to spend too much money, you can negotiate with the owner to share the dredging fee, so that you can wait for the property to be handled in the foreseeable future.
