Are the drainage pipe and sewage pipe the same pipe?

1. Are the drainage pipe and sewage pipe one pipe?

No, the normal drainage in the bathroom is called sewage, and the drainage in the washing machine and kitchen is called wastewater, so both sewage and wastewater can be called drainage. The pipe for discharging domestic sewage is called sewage pipe, and the pipe for discharging rainwater is called rainwater pipe. These two kinds of drainage pipes are pipes in outdoor drainage system.

But sewage drainage and rainwater drainage system can't be confused, because their quantities are calculated according to the drawings, but the node of internal and external pipeline calculation is the first sewage well where the indoor sewage pipeline extends out of the room.

Second, can the toilet drain pipe and sewer pipe be used together?

1, yes, the main purpose of the drainage pipe is to discharge water and rainwater at home, and the sewage pipe needs to be connected to the toilet or squatting pan, which can be used.

2. When the residential sewer is arranged, the bathroom sewer and the bathing pipe should be merged in the same pipe. But before construction, we must pay attention to water sealing or odor-proof floor drain to avoid the backflow of sewage pipes and produce peculiar smell.

3, but also ensure proper layout, otherwise the toilet drainage is difficult, and it will be blocked over time. When planning, the angle must be calculated, and the sewer pipe needs an O-shape and then returns to the sewage outlet, so that the water can bypass, slow down the pipeline speed and reduce the probability of blockage.

Summary: The drainage pipe and sewage pipe are not the same pipe, but if they are arranged in the toilet pipe, they can be combined in one pipe. The specific operation should be based on the construction environment and their own needs, which can reduce a lot of unnecessary troubles.
