Nowadays, the common settings mainly include the direct laying of drainage horizontal pipes on the ground, the ascending plate type, the descending plate type, and the structure layer buried type. The horizontal drainage pipe is directly laid on the same floor on the ground. This method is suitable for the renovation of old houses. The vertical pipe is used in the room, and the toilet is of the rear outlet type. Drainage pipes such as washbasins and showers are arranged on the same floor. The floor drain is set in a side row, close to the riser or without a floor drain.
