How about magnetic levitation floor drain?

First of all, my client is doing this. I want to say that it is not without its shortcomings. Clothes and all kinds of garbage need to be disposed of. Because if there are very small particles containing iron or the like that are very heavy, they are easily adsorbed, affecting the effect and shortening the life. But this kind of thing is rare in life. If your work often involves these things, then there is nothing you can do for the time being. But this is the case for a small number of people, and generally there are not so many things that can be attracted by the magnet and flow out together with the water. There is no need to talk about issues such as drainage and odor prevention. In fact, this technology is not as easy as some people think, it is more complicated. Maglev technology is used in more places than this. The Laifa Levitation Train also uses this technology. In terms of product life, as far as I know pure copper is the most durable material. The Golgar magnetic levitation floor drain is made of pure copper. You can learn more about Golgar Maglev or Golgar Maglev Floor Drain on Baidu. Or click this link web link
