Restaurants can choose to use some special cleaning agents, gradually add cleaning agents to the sewer pipes, let them act on the oil stains in the pipes, and then clean the pipes with high-pressure water guns.

4. Manual cleaning method

If there is no other cleaning method in restaurants, manual cleaning method can be adopted. However, this method consumes manpower and time, and the operation is cumbersome. It is best to send a professional team to check the depth and narrowness of the pipeline before using this method, so as to avoid the tool head or tool getting stuck in the sewer halfway and causing secondary pollution.

By adopting these drainage methods of restaurant sewers, the problems of pipeline blockage or water waste in restaurants can be effectively reduced.
