Why did the design institute design the toilet water supply pipe along the wall?

1. GB 50015-2003 "Code for Design of Building Water Supply and Drainage" gives the water supply quota flow, equivalent, nominal diameter of connecting pipe and minimum working pressure gauge of sanitary appliances. The table gives a table of the drainage flow, equivalent, and diameter of the drainage pipe for sanitary appliances. The diameter of the toilet water supply and drainage pipe of the building water supply and drainage should be determined according to the data in the table of the "Building Water Supply and Drainage Design Code". >>>More

If it is a formal construction project, it is recommended that you still construct according to the drawings and do not change it without permission.

If there is no bend, a straight will be formed, and the foul smell from the sewer will be emitted into the room, and it is because of that bend that part of the water will be stored, and it is that water that acts as an isolation.

If you want to design the drawings with higher quality, I do architectural design. >>>More

The distance between the toilet sewer pipe and the Rose Pavilion is 330 350 from the wall, so that the distance between the center of the toilet drain and the outside of the toilet can be about 420 430, and at least 400. Nowadays, no matter what kind of toilet, the bend and gas have been formed into a whole, so the ground drain should be more than 600 meters from the wall, which is very good for the toilet.
