There are several general treatment methods for blocked sewers in hotels:

1.

A powerful pipe dredge is a chemical cleaning product that can dredge blocked pipes in kitchens and toilets.

High alkalinity can quickly and effectively decompose and dredge all kinds of organic substances (hair, vegetable residue, meat, cotton, etc.) blocking the sewer canal. It can quickly and effectively decompose and dredge all kinds of organic substances (hair, vegetable residue, meat, cotton, etc.) blocking the sewer canal.

second,

put caustic soda into the mouth of the sewer, and then pour a pot of boiling water into it, not a thermos, but a big pot of water.

3.

If the pipe dredging agent was used and the workers were asked to use iron branches to pass through, but the water was not removed later, it is not suitable to use iron branches again, for fear that the corroded canal will be penetrated. You can use thick rattan instead, and the rattan head can nail ten nails of eight inches in length, and stir them around while putting them in, so as to loosen the sundries, then pour in concentrated alkali solution, and then push the rattan out. If this continues for many times, it will be effective.

in addition to the thick rattan, you can also buy a spring channel opener from the hardware store, which is more effective. Salt, white vinegar, straws, etc. used by ordinary people can't work.

some pipelines will scale during use, which will make the inner diameter of the pipeline thinner and even affect the normal sewage discharge. In the above two cases, it is not feasible to dredge particles directly by pipeline dredge or by using pipeline dredge, and it is easy to deal with changing pipelines. If it enters cement during the decoration process, it will be very difficult to dredge, and there are very few people who can handle it effectively, so the cost is also very high. In practical work, the biggest workload is the dredging of municipal pipelines. The use of these pipelines is more complicated, and once they are blocked, the harm is greater. Generally, high-pressure cleaning vehicles are used to clean the pipelines, and the larger the pipeline diameter, the higher the performance requirements for vehicles. Generally, the cleaning range of the common high-pressure cleaning vehicle on the road is the pipeline with a diameter of less than 511 mm. For pipelines with a diameter of 611 or even more than 811, this kind of cleaning vehicle can only rely on luck, which requires the use of ultra-high pressure cleaning vehicles to dredge. If we want to solve the problem fundamentally, we need to clean up all the sludge inside, which requires equipment such as sludge cleaning machine.
