How to completely solve the problem of anti-water in the kitchen sewer on the first floor

? Usually the first floor is a separate sewer, and the water pressure is very low, so it is not easy to block. First, it is necessary to judge whether the supervisor is blocked. I have encountered a situation where the flux is not enough to produce suffocation effect, so extending the sewer pipe can play a certain role.

? What should I do if the sewer on the first floor is blocked and the water flow is reversed?

1, if the drainage is blocked, it is mainly because it is not dredged regularly. You can directly find a property company to dredge the pipeline, which can solve the problem of anti-water.

2. Or we can dredge the sewer at home by ourselves and dredge it with caustic soda, and the effect is still very good. Before dredging, we can also boil another pot of hot water, pour caustic soda into the sewer, and then pour boiling water directly into it. Basically, the blockage phenomenon is not particularly serious, or it will not take long, and it can be directly dredged.

3, because the flux is not enough to produce an effect similar to suffocation, in this case, extend the sewer pipe.

In addition, to be more specific, the blockage of the sewer pipe leads to the backflow of the kitchen sewer, and the blockage is also divided into two situations:

1. When the kitchen sewer is used by itself, it is blocked by its own pipe and can be dredged with a small dredge.

2. If there is no water to pour, the head of the whole building will be blocked, and the kitchen sewer pipe will be easy to scale. It may be necessary to hire a professional master to clean the pipeline, which is more thorough.

In addition to the above reasons, hydraulic conditions and pipes used for sewer pipes will also affect the drainage of kitchen sewers:

1. Residential drainage is generally gravity drainage, and the drainage speed of drainage riser is higher than that of horizontal drainage main pipe. When the sewage is discharged to the bottom of the drainage riser and transferred to the horizontal drainage main pipe, the drainage speed will slow down, especially when the water volume is large, which may cause instantaneous blockage. Sewage forms a short section of positive pressure water column at the bottom of drainage riser. If the hydraulic conditions in this part are not good, the positive pressure water column will be higher. When the positive pressure water column is higher than the kitchen utensils and appliances of the ground floor residence, the sewage will overflow from the kitchen utensils and appliances of the ground floor residence, which is the situation that the sewer is against the water. This is usually caused by unreasonable drainage design.

2. The inner wall of the pipeline will also affect the drainage quality. For example, in the past, the drainage pipes of houses usually used sand cast iron pipes. The inner wall of this kind of pipeline is rough, which is easy to cause dirt "retention". Poor anticorrosion will eventually lead to rust and poor drainage of pipelines.

If the waterproof problem of the ground floor residence is very serious because of the pipeline problem, it is necessary to transform the original drainage pipe and replace it with a pipeline with smooth inner wall, which is not easy to get dirty. Plastic drain pipe or machine-made centrifugal cast iron pipe are two commonly used now.
