1. hair causes sewer blockage: after the sewer is used for a period of time, the hair from bathing will hang on the pipe wall, and if accumulated, it will cause blockage. hair will generally cause toilet floor drain blockage, washbasin blockage, bathtub blockage and shower room blockage. therefore, we should cover the floor drain and other protective facilities when using them. if there is hair, you can pick it up and throw it into the garbage can. how to do when the sewer is clogged with more hair? this kind of blockage is easy to solve. the hand dredger can dredge the water. if it is serious, the pipe dredger must be used.
2. when the sewer is blocked by hard materials, it is also common. some people do not cover the floor drain well, so that some small things fall into the sewer pipe, resulting in blockage, how to solve it? if you can see it with the naked eye, you have to use a hook like tool to pull out foreign objects or vacuum cleaner. if you can't see it, you can use a household vacuum cleaner to try. sometimes it will have unexpected effects. if not, then you have to use professional dredging tools, try to find a dredging cleaning company to solve it.
3. decoration caused by sewer blockage: this is the most easy to happen in house decoration. we have encountered many cases of sewer blockage due to careless decoration. this is absolutely not accidental, so we must take protective measures before decoration. this kind of blockage is generally caused by cement block, tile fragment, sand, coating, woven bag, etc. if it is a woven bag and other soft objects, you can use the dredger to dredge it directly. if it is the cement residue and other hard objects blocked, it needs professional dredging tools to dredge.
4. grease clogging: oil dirt clogging sewers usually appear in the kitchen, and this kind of blockage is generally the scaling on the inner wall of the pipeline. after serious scaling of the pipeline, the sewer is blocked. if it is serious, the dredger can be used to dredge. it is impossible to solve the problem with simple dredging methods. once dredged, it will be blocked again. if it is blocked, it is a vicious circle. if you want to solve the problem thoroughly, you can only use the high-pressure water truck to clean the inner wall of the pipe or replace it with a new one. relatively speaking, the use of high-pressure cleaning vehicles dredge more economical.
