The second floor was flooded.The main reasons for the second floor's overflow were as follows:
1. ** Design and construction of the pipeline **
- The pipe diameter is too thin, there is a problem with the vent pipe, the buried pipeline is damaged, there are obstacles in the pipe, the bottom horizontal pipe is too long, the bend angle is too sharp, the slope is not enough, or even the slope is reversed, the distance between the lowest horizontal branch pipe and the bottom of the vertical pipe or the bottom horizontal pipe is not up to the standard, and the elbow radius is too small when the vertical pipe turns horizontally (the standard is two 45-degree elbows or four times the diameter of the large elbow or variable diameter elbow), etc., will lead to insufficient drainage capacity. Even if the design and construction of the pipeline reached the standard, there was still a small probability of water reversal. However, some of the second-floor pipes were completely in line with the specifications. The distance between the horizontal pipe and the sewage well was short, and the flushing ability was sufficient. The risk of water reversal was very small.
- The drainage overflow function of the three-way pipe connected to the bottom of the sewage pipe and the ventilation pipe was relatively strong, which could prevent water from flowing back to a certain extent.
2. ** Construction waste blockage **
- During the construction and renovation stage, some workers had bad habits. They poured cement, glue, and other construction waste into the sewer, which could easily block the pipeline and cause water to flow back. Or they would stick to the inner wall of the pipeline and make the actual diameter smaller, resulting in a decrease in sewage discharge capacity and a hidden danger of water return. However, the normal pipeline flushing ability was strong, and some of the construction debris might be washed away. Such problems rarely occurred in the hardcover room.
3. ** Inappropriate or careless use by the residents upstairs and maintenance issues **
- Upstairs residents would drop large sundries such as sanitary napkins, plastic, towels, hair, bottles, etc. into the sewer through the toilet bowl, which would cause blockage. In places where toilets were commonly used, due to the small internal diameter of the toilet, large sundries were easy to get stuck in the toilet, so the blockage of the toilet after the renovation period was relatively rare.
- The whole bucket of water upstairs was poured into the toilet, and the water flow in the vertical pipe was too large or there was a strong pressure, causing the reverse flow and bubbling. When the food residue in the vegetable washing basin was poured into the kitchen pipe, the oil stain was easy to condense and solidify to form a stain or blockage. If the property was negligent or incomplete, it was easy to cause the reverse flow.
There were the following solutions to the problem of water overflow on the second floor:
1. ** Rectification, maintenance, and dredging of pipes **
- For new houses and houses under the guarantee period, they would first find the developer or property management to be responsible for them. If it was a problem with the design and construction of the pipeline, it had to be repaired or rebuilt. At least, it had to meet the specifications of the Jianshui Standard and pass the ball test. During the renovation, the developer may be required to substantially increase the slope of the horizontal pipe. If there is a sealing ring or accumulation protruding from the inner wall of the pipe at the pipe joint, it will affect the passage of sewage and dirt, especially if the horizontal pipe has been blocked. It is necessary to remove the bulge at the joint and greatly increase the slope. When the bottom horizontal pipe is a cast iron pipe, it can be disassembled and cleaned before being installed again. The property can use the vehicle high-pressure water flushing dredge machine (strong dredging ability and does not damage the pipeline) and other equipment to dredge. For the pipeline that is easy to reverse, the inspection and dredging should be strengthened.
- In the event of a water spill, the property owner must immediately rush to the building and inform the upstairs to suspend water use or close the unit water supply valve to stop the water spill, dredge the pipeline and clean up the hygiene. If the property owner suffers losses due to the property, the property owner shall compensate according to law.
2. ** Regarding preventive and other measures **
- The addition of a check valve during renovation could prevent the kitchen pipeline and the drainage pipeline of the bathroom from being filled with sewage.
- The second floor had an independent diving system, which could solve the problem of water returning once and for all.
- A water alarm was installed to send out a remote alarm when water returned to the ground to avoid greater losses.
- It can be installed with a pipe sealing plug, and its multi-layer silica gel sealing ring can seal the sewer pipe. The gravity check valve at the bottom can only be opened when draining water, and it is usually closed. It can effectively prevent insects, odor, and overflow. It is suitable for washing machines, washbasins, sink pipes, and other sewer pipes. At the same time, all owners and tenants should be reminded to use the drainage pipe in a civilized manner. The property management can post a notice board in a prominent position, or remind the residents to use the pipe reasonably according to the law through mass text messages and owner groups.

Hong Xiu website stipulated that the contracted novels could not be flooded, so what was considered a flooded novel?Hong Xiu website stipulated that the contracted novel could not be flooded. Then what was considered a flooded novel? Generally speaking, waterlogged novels referred to novels that added too much nonsense, fictional plots, or unnecessary descriptions, making the story and characters of the novel unclear and affecting the reader's reading experience.
In addition, waterlogged novels could also be manifested as novels with too many words, too long plots, and lack of cohesion, wasting readers 'time and attention.
In order to avoid the emergence of waterlogged novels, authors can pay attention to controlling the number of words in the writing process, rationally plan the story, simplify the language expression, and improve the reading efficiency. At the same time, they could also strengthen their self-examination to prevent unnecessary waterlogging in their own or other people's works.
