In home renovation and daily use, the drainage system is an important part of the bathroom. According to the different drainage methods, the drainage system can be divided into two types: upper drainage and lower drainage. Both types of drainage have their own advantages and disadvantages, and are suitable for different occasions and needs. This article will introduce the difference between upper and lower drainage in detail to help you better understand and choose the right drainage method for your situation.
1. Definition of upper and lower drainage.
Upper drainage means that the drainage pipe is laid upwards and the sewage is discharged into the sewer pipe by gravity. This type of drainage is often used in buildings such as high-rise buildings or villas. Downward drainage refers to the downward laying of drainage pipes and the discharge of sewage through floor drains or drains. This type of drainage is common and is suitable for both residential and commercial buildings.
Second, the advantages and disadvantages of upper and lower drainage.
1.Advantages of upper drainage.
1) Space-saving: Since the drainage pipes are laid upwards, there is no need to occupy ground space, so sanitary ware can be reasonably arranged in a limited space.
2) Unrestricted: It is suitable for various occasions, especially in some special cases, such as the situation that there is no sewer pipe or cannot be installed.
3) Good quietness: because the water flows downward, it is not easy to produce noise, and it has less impact on the living environment.
2.disadvantages of upper drainage.
1) Complex installation: Due to the need to lay a long pipeline, the installation is more complicated and the cost is higher.
2) Easy to block: Due to the long pipeline, it is easy to cause blockage, which needs to be cleaned and maintained regularly.
3) Affected by gravity: Because it is gravity drainage, it is easy to be affected by the length of the pipe and the height of the water flow, and there may be poor drainage.
3.Advantages of lower drainage.
1) Easy installation: Due to the short pipeline, the installation is relatively simple and the cost is lower.
2) Not easy to block: due to the short pipeline, it is not easy to cause blockage, and the maintenance is more convenient.
3) Wide range of application: suitable for various occasions, especially some conventional residential and commercial buildings.
4.Disadvantages of lower drainage.
1) Occupy space: Due to the need to install floor drains or drains, it needs to occupy a certain amount of ground space.
2) Loud noise: Because the water flows upward, it is easy to produce noise, which has a certain impact on the living environment.
3) Limited by building structure: The drainage method is limited by the building structure, which needs to be reasonably planned in the building design and construction stage.
3. Applicable scenarios of upper and lower drainage.
1.Upper drainage is suitable for high-rise buildings, villas and other buildings. Due to the high floors of these buildings, the use of upper drainage can avoid the problem of poor drainage due to insufficient gravity. In addition, in some special cases, such as when there is no sewer pipe or it is not possible to install a sewer pipe, the upper drainage method can also be considered.
2.Underdrain is suitable for general residential and commercial buildings. These buildings have moderate floor heights, use underdrain to better meet the needs of daily use, and are easy to install and inexpensive. During the building design and construction phase, drainage needs to be planned to ensure the smoothness and reliability of the drainage system.
To sum up, both upper and lower drainage have their own advantages and disadvantages, which are suitable for different occasions and needs. When choosing a drainage method, you need to consider it comprehensively according to the actual situation to ensure that you choose the drainage method that suits your situation.
