Sewer pipe size differentiation, is it better to drain more or smaller water pipes?

The distinction between the size of the water and the pipe mainly depends on its inner diameter, its inner diameter is large, the pipe is thick, and the pipe is thin.

Common sewer pipe sizes are as follows:

1. The diameter of the riser pipe used for drainage in the residence shall not be less than 75 mm, that is, the diameter of the sewer pipe for drainage shall be 75 mm.

2. The drainage branch pipe connected to the washbasin, washing basin, bathtub and sanitary basin has a diameter of 32 mm, and the sewer pipe with a diameter of 40 mm can be used for larger specifications.

3. The diameter of the drainage branch pipe connected to the urinal and urinal is 50 mm, and the sewer pipe is 75 mm.

4. The diameter of the drainage pipe connected to the toilet is 110 mm.

5. The diameter of the drainage pipe of the washing tank and sewage pool in the public canteen and restaurant shall not be less than 75 mm.

6. The diameter of the drainage branch pipe of the public bathroom shall not be less than 75 mm, and the diameter of the main pipe shall not be less than 100 mm.

There is a distinction between the size of the sewer network, if you want to calculate according to the largest of these official websites, it is 50 centimeters and the smallest is 5 centimeters, there are a total of ten different levels, and every five centimeters is a size.

The size of the sewer pipe is the difference of the diameter of the pipe, the main material is PVC pipe, and the main pipe diameter is 60, 80, and 100.

Sewer pipe size differentiation. The size of the sewer pipe is very well distinguished, the main sewer pipe must be large, the thick molecule must be small.

If you want to distinguish the size of the sewer pipe, you need a vernier caliper, the diameter of the main sewer pipe, and then according to the vernier caliper, the diameter of the sewer pipe is compared with the pipe standard to know how big the sewer pipe is.

The size of the sewer pipe is different, and their scale will be different, because the toilet and the basin room or the toilet are all decorated with different types of pipes, and the thickness of the pipe can be determined according to its water consumption and sewage volume.

Sewer pipes are divided into one upper and lower pipes and sewer pipes, so they are used separately.

The sewer pipe is mainly divided into length, not size, and the size is basically the same diameter and nozzle.

The size of the sewer pipe is seven points, and the size of this and its size is the size of the wind, and the pipe of his sewer is divided by his thickness according to his size and specification.

Sewer pipe size distinction sewer pipe big movie refers to the use of large pipes, sewer pipes, small pipes with small pipes.

The size of the residential pipe is more convenient for your home's water.

Flow, then in this case, in terms of size, as long as it is reasonable, then it will make your home water pipe drain the water faster, or he will not put the smell will not have a backlash.

You measure the diameter of the pipe through the sewer pipe, and then you can calculate through the diameter, how big and thick the pipe is, if you don't know it well, you can go up and check some knowledge about this aspect.

Is it better to use 10cm or 20cm for the sewer pipes used in the home? The personal opinion given by the home miscellaneous altar is that if it is a self-built house, one floor, two floors or even three floors, you can choose 11cm cm. For 20cn pipes, it is not recommended for you to choose.

Why do you say that, let's first answer the question of some specifications and sizes of drainage pipes in the house.

Drain mains. The so-called drainage main pipe includes the drainage riser we use and the horizontal outlet pipe for drainage, which are called drainage main pipes.

Like the self-built house in our home, it is at most three floors. According to conventional empirical data, it is perfectly possible to choose a 110mm outer diameter pipe for the main drainage pipe of a three-storey building. Of course, if we choose 150cm, that is, we often say that 160cm outer diameter pipes are no problem, but it is not recommended to choose 200mm.

This type of pipe is too thick, not much use, and can be easily damaged.

: Drainage branch trunk. The so-called drainage trunks are the horizontal drainage pipes in the bathroom at home, which are used to connect the various drainage ends in the room.

For example, the drainage of floor drains, the drainage of washbasins, and the drainage of toilets must be connected to this pipe. For the branch pipe for drainage, I personally recommend that you also choose a UPVC pipe with an outer diameter of 110 mm. At this time, it is not recommended to choose 160mm and 200mm drainage pipes.

Selection of drainage branches. For the drainage of the branches, like the bathroom in the home, there are three main types.

They are the drain branch of the floor drain, the drainage branch of the washbasin and the drainage branch of the toilet. For these three places, the personal choice suggestion is to choose a 75mm drainage pipe for the floor drain and a 50mm drainage pipe for the washbasin. For toilets, choose a 110mm drain pipe.

Try not to choose the wrong size of these sizes to facilitate the installation of toilets, floor drains and washbasins.

No. Appropriate as well. The tube is too small and prone to clogging.

The proper diameter of the water is a rapid, which can carry out sediment and debris. If the pipe is too thick, the effluent will become advection, and sediment and debris will be deposited, and it will be clogged after a long time. In the middle of the city's sewers, a large manhole is deliberately built to deposit sediment, which is the reason.

1.You have to say that the residential unit drainage system is composed, the indoor drainage horizontal pipe is discharged into the drainage riser and then connected to the discharge pipe to the outdoor community drainage pipe, and the community drainage system includes the unit discharge pipe into the sewage inspection well, and the community sewage pipe enters the septic tank and comes out simply, and finally discharges into the large municipal drainage pipe.
