Is the kitchen sewer on the second floor blocked on the first floor or the second floor?

It could be that the main pipe on the first floor is blocked.

First of all, we must communicate with the property company about this matter, the common problem faced by the residents on the first floor, because the upstairs residents did not install the sewer pipe crusher, but the garbage that should not be flushed into the sewer pipe was irresponsibly discharged into the sewer pipe, and the best way to solve it is to ask someone to install an independent sewer to completely solve the problem of waterproofing. The introduction of the current house to the first floor is one of the highlights.

When we live in a building, we occasionally encounter a sewer blockage and then backwater, especially for low-rise residents. This is the type of headache that should be encountered most often on the first or second floor. Because all the upstairs residents have to flow through the first or second floor, if there are residents upstairs who flush some large particles of waste into the sewer along with the wastewater, there is a risk of blockage.

If the residents of the upper floors often pour a lot of waste water into the sewers, the first or second floors are easy to block over the years. So how to tell if the second floor is blocked on the first floor or the second floor? There are several aspects to this.

If the kitchen sewer on the second floor is backwater, there will be the following possibilities: one is that the first floor is blocked, if this is the case, then the sewer of his house must also be backwater. That is, you need to do a test, that is, go to the first floor to release water to see if the water in his house is also anti-water, if there is the same situation, then the main pipe under his house is blocked.

If there is no backwater in his house, then it means that there is another possibility, and the main pipe before the first floor to the second floor is blocked.

In addition, in addition to the blockage of the main pipeline from the first floor to the second floor, there is also a possibility that the elbow pipe of your own home, that is, the branch pipe is blocked. This kind of test needs to go to the resident on the third floor to check the drainage, if the sewer of his house does not reflect the water, it means that the branch pipe of your house is blocked. It may be that something has fallen into it or the oil is too thick for the drain to pass.

Finding a professional unclogging staff or buying that kind of sewer pipe dredging fluid can solve the problem. If the main pipeline is blocked, then it is enough to find the property to dredge it.

Go to the first floor to do the test, this is a method for some old-fashioned buildings, because the buildings built before are basically upstairs and downstairs are a main pipeline, so the first floor is blocked can affect the residents above the second floor. But now with the construction of new buildings, this can be avoided. Because basically the first floor is an independent pipe, so if the new building is new, the second floor will be flooded, which can basically rule out the possibility of blocking the first floor.

1. The drainage speed of the general drainage riser is greater than that of the drainage horizontal trunk pipe, and when the sewage is discharged to the bottom of the drainage riser and transferred to the drainage horizontal trunk pipe, instantaneous congestion will be generated, and a short period of positive pressure water column will be formed at the bottom of the drainage riser, if the hydraulic conditions are not good, (such as the drainage riser and the drainage horizontal trunk pipe are not connected with two 45 elbows, the diameter of the drainage cross trunk pipe is small, the slope is small, or when the blockage occurs), the positive pressure water column is formed relatively high, when the positive pressure water column is higher than the sanitary appliances of the ground floor residence, Sewage overflows from the sanitary appliances of the houses on the ground floor.

2. The drainage pipe is generally a sand mold cast iron pipe, the inner wall is rough, easy to hang dirt, and the anti-corrosion is not good and easy to rust, resulting in poor drainage. The inner wall of the plastic drainage pipe and the mechanism centrifugal cast iron pipe is smooth, and the dirt is not easy to hang up and cause blockage, and the water passing capacity is 10% 26% larger than that of the sand mold drainage cast iron pipe.

3. The slope of the drainage horizontal trunk pipe during residential construction generally meets the standard slope, and the flow rate of sewage in the pipeline can reach the self-cleaning flow rate. It is normal for the house to settle due to its own weight and unreal foundation when it is first built, but it is not attached great importance to the design and construction, and corresponding measures are taken, resulting in a large amount of house settlement, and the drainage outlet pipe is pressed, resulting in the reduction of the slope of the drainage outlet pipe, or even the reverse slope, and the drainage outlet pipe will be crushed when it is serious, resulting in poor drainage.

In this case, it is generally more likely that the first floor is blocked. In this case, you can call the sewer company directly and ask a professional to carry out the repair.

It is the first floor that is blocked, because only when the lower floor is blocked, the upper floor will have a backwater phenomenon.

The first floor is blocked, and the drainage of a building is concentrated on the second floor, and large particles appear in the sewage, which is easy to block, causing the sewer to back.

If the water return indicates that it is a problem on the first floor, if it is not returned, please go to the third floor to test the water to see if the third floor is backwater, if the third floor is normal, then determine that it is blocked between the S bend of your kitchen and the riser.

If the first floor does not reflect the water, it may be that the riser pipe from the first floor to your house is blocked, and if the third floor does not reflect the water, it is your branch pipe blocked.

The 2nd floor is a very tragic floor...

The 1st floor of the sewer pipe is an independent pipe, and the 2nd floor and above are only a common pipe. . .

So, it has nothing to do with the residents on the first floor...

The lower layer is blocked, and the upper layer is backwatered; The upper layer is blocked, and the lower layer leaks water.

The first floor is blocked, the problem of the supervisor, find a professional dredging master to pay for the property.

Now science and technology has entered the era of robots, the era of big data, the era of remote control, such a small thing can stump the real estate management department, sewage pipeline management has been incorporated into the big data management system, when the sewer of the owner of the community is blocked, the city data management center gets the information for the first time, the information is automatically transferred to the property management department of the community, and the property management department arranges professional dredging personnel to dredge, and it is absolutely impossible for sewage overflow to occur.

(1) There are two main situations of backwater:

1. In the process of daily use, the pipe is blocked due to the discarding of items and wastes into the main sewer pipe (drainage pipe), and the daily life wastewater of the upstairs neighbors flows into the blocked main sewer pipe, and the problem of backwater will occur.

2. When the upstairs neighbors concentrate on discharging wastewater into the sewer pipe, the air in the pipe will be compressed, so as to produce pressure on the water supply in the trap connecting the main sewer pipe on the lower floor, resulting in backwater.

b) How to avoid backwater:

Installing a Hammond Kitchen Drain Anti-Backcheck Valve Check Valve can solve the problem, which is simple and fast, and can prevent backwater and odor.

3) How to prevent water backlash of check valve:

The check valve automatically opens and closes by the force of the water flow. Only allow water to flow in one direction, when the water flows backwards, the water pressure against the valve plate, the valve plate automatically closes, so as to play the role of anti-water backlash.

It was the main pipe on the first floor that was blocked.
