The main pipe, main pipe, and branch pipe had different definition and functions in the water supply system. The following conclusions:
The main pipe referred to the pipe section from the indoor main valve (or water meter) to the water supply standpipe. It was usually in the form of a standpipe, responsible for guiding water from the water source to various locations in the building. The main water supply line was usually the main water supply line in the system and could span multiple floors.
The main pipe referred to the pipe section from the water source to the most unfavorable point. The most unfavorable point could be the farthest water distribution point or the highest water distribution point. The main pipe was usually in the form of a vertical pipe or a horizontal pipe, because it must have small pipes that were divided from other pipes. These small pipes were branch pipes. The function of the main pipe was to connect the pipe section of the household pipe and the branch pipe to carry out up and down transportation.
The branch pipe was a water distribution pipe on the same floor, starting from the main pipe and ending at the water distribution valve of the faucet or sanitary ware. The branch pipe was usually a horizontal pipe that connected to sanitary ware or other water points.
In summary, the main pipe, the main pipe, and the branch pipe have different meanings and functions in the water supply system. The main pipe was the main water supply line, the main pipe was the pipe section that connected the household pipe and the branch pipe to transport water up and down, and the branch pipe was the water distribution pipe on the same floor.

The difference between the UpPVP spiral pipe and the drainage pipe was that the UpPVP spiral pipe was a special type of drainage pipe with a noise reduction function. The inner wall was smooth, and the noise during drainage was low. The drainage pipe was an ordinary pipe with no noise reduction function. Therefore, the upvee spiral pipe could reduce noise during the drainage process, but the drainage pipe did not have this function.

When the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods can be used. According to the Design Standard for Building Water and Waste Water, when the sanitary ware drainage pipe is vertically connected to the horizontal drainage pipe, a 90° inclined tee should be used. When the horizontal branch pipe is connected with the vertical pipe, it can adopt a three-way or four-way downstream pipe and a 45° inclined three-way or 45° inclined four-way pipe. In a special single-standpipe system, the horizontal branch pipe and the standpipe can be connected by special accessories. In addition, according to some provisions of the Building Water and Waste Design Code, when the drainage stand pipe is only equipped with a top vent pipe, the vertical distance between the lowest drainage horizontal branch pipe and the stand pipe bottom shall not be less than the specified distance. According to the Connection Design and Material Selection of Building Drainpipe Branch and Horizontal Main, when the drainage branch pipe on the upper layer of the horizontal main drainage pipe is connected to the horizontal main drainage pipe, it is recommended to use a 45° inclined tee to connect it from the top of the horizontal main drainage pipe. To sum up, when the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods such as 90° inclined three-way, downstream three-way or downstream four-way, 45° inclined three-way or 45° inclined four-way can be used.

The difference between the horizontal branch drainage pipe and the horizontal main drainage pipe was their function and connection method. The horizontal branch drainage pipe was a horizontal pipe section connected to the sanitary ware, usually connected vertically or diagonally to the main pipe. It was used to distribute water to different zones or floors and supply specific faucet or equipment through the horizontal branch pipe. The horizontal main pipe was the main pipe in the system, also known as the main pipe. It was usually in the basement or buried. It went from the water source to the most unfavorable point. The most unfavorable point was usually the farthest water distribution point or the water distribution point at the elevation. Therefore, the difference between the horizontal branch pipe and the horizontal main pipe was their function and location.
Spiral drainage pipe

Spiral drainage pipe was a kind of pipe used in building drainage system, which had some characteristics and advantages. Spiral drainage pipe has the following characteristics:
1. Reduce noise: The design of the spiral drainage pipe can effectively reduce the noise pollution caused by drainage. The measured results showed that compared with the traditional cast iron drainage pipe, the noise of the spiral drainage pipe was about 2 to 4 decibels lower, and it had a silencing effect.
2. To prevent the damage of the floor drain seal: The spiral structure inside the spiral drainage pipe can reduce the pressure fluctuation in the pipe, avoid the damage of the water seal caused by the negative pressure of the upper user and the positive pressure of the bottom user, and improve the stability of the drainage system.
3. Increase drainage efficiency: The internal spiral structure of the spiral drainage pipe increases the friction resistance of the water flow, preventing the water flow from blocking the pipe due to inertia, improving drainage efficiency and reducing the occurrence of blockage accidents.
4. [Double silencing effect: Hollow wall spiral drainage pipe is a special structure of spiral drainage pipe. It has a double-layer structure and honeycomb-shaped holes, which can further isolate noise and have a better silencing effect.]
In general, the spiral drainage pipe had the advantages of reducing noise, preventing the damage of the floor drain seal, and improving drainage efficiency. They are commonly used in the drainage system of buildings, especially for the drainage of single standpipes in high-rise buildings.
Municipal sewage interception pipe

The municipal sewage interception pipe was a water pollution treatment project. By constructing and transforming the sewage pipeline inside the sewage generating unit and connecting it to the sewage pipeline system under the town road, the sewage was finally transported to the sewage treatment plant for central treatment. This project played an important role in urban sewage treatment. The goal of the sewage interception project was to intercept and concentrate sewage to reduce pollution to rivers and water bodies. In order to achieve this goal, it was necessary to dismantle the original sewage treatment facilities, renovate and build sewage pipes, and strengthen the sewage collection and treatment capacity. In addition, the sewage needed to be pre-treated to ensure that the sewage reached a certain treatment standard before entering the municipal sewage pipe network. The implementation of the sewage interception project required the investment and support of the government. At the same time, it was necessary to establish a corresponding work system and assessment mechanism to ensure the smooth progress of the project. At present, some cities have begun to implement sewage interception projects and have achieved certain results. However, there were still some problems in the implementation process, such as old and damaged pipe network, sewage overflow, etc., which needed to be further solved. In general, the municipal sewage interception pipe was an important water pollution control project, which had positive significance for improving the quality of the urban water environment.

The sewage interception technology was a water pollution treatment project. By constructing and transforming the sewage pipeline inside the sewage generating unit and connecting it to the sewage pipeline system under the city road, the sewage was transported to the sewage treatment plant for treatment. This technology was the most direct and effective engineering measure in the treatment of black and smelly water bodies, and it was also the premise of other technical measures. The sewage interception pipe could control the discharge of sewage within the city, including sewage outlets, rainwater pipe outlets, etc. It laid sewage interception pipeline along the river and lake, and reasonably set up pumping stations to intercept the sewage and incorporate it into the urban sewage collection and treatment system. The implementation of the sewage interception pipe project needed to consider the elevation of the overflow device's discharge outlet and the water level of the water body, and set up a non-return device to prevent reverse flow during heavy rain. However, the implementation of the sewage interception and management project faced some limiting factors, such as the large amount of work and one-time investment, the difficulty of project implementation, and the long period. In addition, the sewage entering the sewage treatment plant after intercepting the sewage pipe may cause greater operating pressure on the existing urban sewage system and sewage treatment plant, so bypass treatment may be needed.
