How much does it cost to clear the sewer?

In general, it ranges from 50 to 200. Details are subject to the actual door-to-door dredging fee, and the price is for reference only.

Dredge the drainage pipeline with caustic soda or directly with boiling water. Dredge back and forth at the sewer entrance and exit, and rinse with water. If the pipe blockage is not serious, pour one tablespoon of washing powder into the sewer pipe and three cups of hot water. To ensure the smooth sewer, you can roll the plastic wrap into the sewer, and cut the bottom of the thin plastic bag into a tube and put it into the sewer. If the sewer pipe is slightly blocked, you can pour an appropriate amount of alkali into the sewer. If the sewer is not blocked but smells, the principle of water seal can be used to prevent the smell from coming out.
