Property pipeline cleaning

Hotels need to manage and maintain the use of * * * parts and * * * facilities and equipment. The main sewer network is a public * * * pipe network, which belongs to the daily maintenance 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.

There are several cleaning methods for pipelines:

1, chemical cleaning uses chemicals to clean pipelines, mainly using temporary pipelines and circulating pump stations for circulating chemical cleaning. This technology is flexible, fast and thorough.

2. High-pressure water cleaning uses a high-pressure water jet of more than 50Mpa 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.
