In 1, the China development is not yet mature, it is not comprehensive enough, leading to ignore some elements of the design; (with the drainage layer belongs to the concealed drainage system, whether it is in or after the drop pipe drainage system should be carried out design, pipe diameter calculation is different from the interlayer row, pipe material should also indicate the design sure, U-PVC material).
2, the lack of professional construction team; (as everyone knows, the China construction contract model, the slope is not enough to block and pipe joints Water Leakage etc are not detailed construction caused by the details reflect the professional, the reason why we have an aversion to the same layer drainage is in fact the construction details are dissatisfied, rather than system products)
3, the so-called professional customer service service is not professional, some are purely Huyou you; this makes you think (the same layer drainage pipe blocked, must knock ground or false hit the wall, in fact, professional customer service will help you analyze the reasons, the reasonable design and construction without error, according to drawings, from the inlet to help you clear)
4, the European toilet with the drainage system in the same floor, and China has, without affecting the structure and decoration of the premise, design and construction of how to combine the two?
5, 5CM water is directly related to the indoor air quality and the probability of pipeline blocked, so professional measures, found that many construction units are to cope with the task, the result is less than half of households in the toilet, smell gas.
