1, remove debris. If the sewer is blocked by sundries and stains, it is good to remove the sundries. You can reach into the sewer with a long handle and take out the sundries. In order to speed up the dredging of sewers, it is recommended that you clean them while draining.

2, slender hook wire assistance. If the sewer is still blocked after the removal of large debris, then the slender hook wire is needed for assistance. The corner of the sewer is opened, and the sewer is dredged by pulling the slender hook wire up and down.

3, washing powder dredge. Usually, the sewer in the kitchen or bathroom at home is blocked, and it can also be dredged with washing powder, which is convenient and practical. Pour washing powder, hot water and vinegar into the blocked sewer and wait for half an hour to clear it.

4. Log dredging method. Insert a round wooden stick with a diameter similar to that of the sewer nozzle into the pipeline, add a certain amount of clear water, and then twitch quickly. Under the dual action of suction and pressure, the sundries in the sewer can be washed away, and the sewer will be unimpeded.

5, pipeline dredging agent dredging method. If the reason of sewer blockage is that oil adheres to the inside of the pipeline, the space inside the pipeline will shrink smaller and smaller, and finally it will be easily blocked by various sundries. At this time, it is necessary to use a special pipeline dredging agent to dissolve the grease, and the pipeline will naturally be unblocked.
