What happened to the sewer on the first floor? -What can I do to solve the problem-

The residents who live on the first floor are most disgusted with the problem of sewer anti-water, which not only affects the drainage of daily life, but also the water coming up from the sewer is particularly dirty, with a lot of harmful bacterial substances and a particularly strong odor, which has a great impact on normal life. Then Bian Xiao will tell you the reasons and solutions for the water flowing back in the sewer on the first floor.

1. The reason why the sewer on the first floor is upward is 1. There are many sewer pipes. The house was decorated with old-fashioned desert cast iron pipes. The inner wall of the pipe made of this material is very rough, and it is easy to accumulate dirt and garbage because of the aging and rust of the pipe wall, which leads to the narrowing of the inner diameter of the pipe until it is blocked.

2. Positive pressure water column Under normal circumstances, the sewer drainage of high-rise residential buildings only flows downwards automatically by gravity, which basically enters the drainage riser first, then the horizontal drainage pipe, and finally the drainage shaft. Therefore, when sewage flows from the vertical pipe to the horizontal vertical pipe, there will be water flow blockage and short-term positive pressure water column. At this time, if the vertical and horizontal pipes are improperly installed, the positive pressure water column will be too high, and once it is higher than the pool, sewage will overflow from these pipes.

3, the settlement of the house because the weight of the house itself is not enough, and it is not noticed during the decoration construction, it will lead to excessive settlement of the house, and then squeeze the drainage pipe, which will slow down the drainage speed and make the drainage poor until the slope is reversed, so there is a problem of anti-water.

4. The floor is special. Usually, if there is no independent sewer on the first floor, there will often be a situation of anti-water on the first floor. This is mainly because the entire residential building uses sewers, and the first floor is located at the bottom of the pipeline. There is not enough water pressure to discharge the sewage. With accumulation, there will be a situation of anti-water.

Second, the solution of the sewer on the first floor is 1. If the sewer on the first floor is for residents' own use, it means that the drainage pipeline on the first floor is blocked. You can help dredge the pipeline by dredging agent or dredging machine, or if it is serious, you need to contact professional workers for home maintenance.

2. If the residents on the first floor don't use sewers, the main drainage pipe on that floor is probably blocked. In this case, it is necessary to impact the sewer pipe with a high-pressure water wheel to remove the dirt on the pipe wall and dredge the sewer pipe.

3. It is also possible that the underground shaft is blocked and the outlet of the drainage channel is blocked. In addition, the drainage upstairs causes pressure in the sewer pipe, which causes the sewage in the pipe to be pushed back. It is mainly to confirm whether the angle of the sewer pipe entering the sewer pipe is correct.

The above content is what Bian Xiao wants to introduce to you about the reasons and solutions of sewer backflow on the first floor. I hope I can help you to some extent. For example, when decorating, consider the problem of sewer blockage and backflow, select good pipes and install backflow devices. At the same time, in daily use, we should also pay attention not to discharge too much garbage into the sewer to avoid the trouble caused by pipeline blockage.
