Why is the downpipe on the second floor the easiest to block?

Follow up report on "Xiaoshan Zhu's 160 square house turned into a" septic tank "

Yesterday, we published a story about Ms. Zhu Xiaoshan's 160 square meter house turned into a "septic tank" due to sewer blockage and toilet overflow. After the WeChat official account was sent to the north peak, the netizens asked, "is it the two floor?" "the sewage pipe on the two floor is always a difficult problem."

As like as two peas in the south, the nine yuan in Gongshu District, Mr. Wen called us yesterday. "My family and today's newspapers are just the same, reflecting many times, but they are not effective. We call people who specializes in sewers every year, but they overrun in a few days."

Mr. Wen said that five years ago, the toilet and floor drain of his family began to overflow with sewage, which could not be dredged several times, but he had to use a rubber stopper to plug the floor drain and press the bucket on it“ The most exaggerated one was two or three years ago,冷氣 機 出 風口 滴水 when the rubber stopper was removed, the sewage went straight to the roof like a fountain... "He said that now, he has moved, and the house is for rent, but because the sewer always has problems, it is difficult to rent out the house. It's the same with the neighbors. They are pitying each other for the same disease and are bothering each other.

The floor drain of the toilet is pressed with 11 cement bricks

Yesterday, the reporter came to nanjiuyuan, Daguan. Mr. Wen was not at home. His neighbor, aunt Yu, took the reporter to her home.

Aunt Yu's bathroom is about 6 square meters. Next to the toilet, there are three piles of cement bricks. There are 11 pieces in total. Under the bricks, you can see a pool of yellow water overflowing, emitting a bad smell.

Aunt Yu said she had lived here for more than 20 years and had no problems before. But five years ago, the drainage pipes of the washing machine and the floor drain beside the toilet began to block the overflow. At the beginning, she just found someone to dredge it, but after a few months, it began to block again. After several times, aunt Yu had to move the washing machine away and connect it to the floor drain in the shower area.

"Once, the sewage in the floor drain was ejected nearly one meter high. Another time, the family went out. When they came back, the water flooded the mountain, and the sewage flowed from the toilet to the living room. " Aunt Yu had no choice but to move more than a dozen cement bricks to hold the leak firmly.

"We and our neighbor's bathroom should be connected to the same downpipe, so one of our two families is blocked, and the other one must be blocked. Our downpipe, which leads to the supermarket downstairs, is aging. Many professional masters shake their heads and say they dare not repair it. For five years, the community has been here many times, but it still hasn't been solved.

The structure of aunt Yu's building is also somewhat special. The first floor is a shop, there is a large supermarket, and the second floor and above are residents' houses. Walking into the supermarket, on the roof of the hall, you can see all the water pipes. The staff of the supermarket said that the sewer has always been their worry: "it often leaks and is often repaired. In the most serious case, there was water leakage all over the cash register. "

Relevant staff of Daguan Nanyuan community said that they have been pushing forward to solve the problem. In addition to the overflow caused by the aging sewer on the second floor, the problem of private sewer on the upper floor is also very serious, and the sewage flows to the platform on the second floor. Last year, Gongshu District launched the special action of "zero direct drainage" of rainwater and sewage diversion. The relevant departments came to see this special building. After research, they decided to temporarily collect the private pipes of the residents and drain them to the same sewer pipe, and then change the pipe to build a new pipe to completely solve the problem.
