The old old man of Ji'nan invented the trick to dredge the sewer
business newspaper Ji'nan news (the correspondent Cui Yanhong) is a difficult problem for many families. The family of Duan Huigong, who lives in the dormitory of the Shandong Geological Survey Bureau, has also been annoyed by this problem. After months of hard work, Duan and his wife invented a sewer dredge.
73 years old, his wife is also 70 years old, his family is 70 years old, he lives in two buildings, because the first floor is a separate sewer pipe, the two to five floor is a sewer pipe, every time the drain pipe is blocked, the family is bound to suffer, from the third years to buy a house, the family has constantly blocked the overflow of sewage situation. In the past two years, the frequency of congestion has increased significantly. In 2010, it stopped up three times, making the uncle and his wife worried. Some households were forced to spend money to change the pipeline because they were old and blocked. Considering that there is no one upstairs, once the sewage is blocked on the third floor, the section of Grandpa's family will suffer even downstairs. So, uncle Duan and Xu aunt began to try to dredge themselves, hoping to find a simple way.
the old two bought a 4 metre long soft steel wire from the outside. After several failures, they finally succeeded. "In this dredger, the key part is a plastic tube with a length of about 1.4 meters long. I bend the plastic pipe through a fire. I stuck it at one end of the sewer well, and the steel wire passed the bend through the plastic pipe." Duan uncle said, since this invention, no fear of sewer blockage.
