Is there a clear provision in the national building law on whether a floor drain should be installed

Considering the possibility of water seepage from floor drains and the fact that the kitchen floor generally does not accumulate water, the relevant design standards do not advocate the installation of floor drains in household kitchens.

Hello, there is no such provision, considering the possibility of water seepage of the floor drain and the kitchen floor is generally not waterlogged, the relevant design standards do not advocate the installation of floor drains in household kitchens. However, it is still recommended that you can install a floor drain, because in case of water seepage, etc., it will cause damage to the downstairs wall, which will cause unnecessary trouble! Hope the answer helps!

The plaintiff said that it was the destruction of the bolt check port of the sewer, in fact, the bolt check port of the kitchen on the second floor was not damaged by the improper operation of the maintenance master, and the stain of the bolt check mouth can be seen that the bolt check port has long been broken, and the photo is provided by the decoration company. When the water of the upstairs residents penetrated into the kitchen on the first floor, it was not found in time that the water was from the sewage of the drainage main of the whole building, and penetrated into the kitchen floor drain branch pipe, which is the pipe of the kitchen floor drain upstairs. How much responsibility? If a reply is filed, what should be the focus of the reply?

Hello, if according to what you say, the maintenance worker is not responsible, first of all, the maintenance worker is to dredge the pipeline, the responsibility is only to dredge the pipeline, and there is no responsibility to check for damage, secondly, if the repair is determined that there is no damage to the pipeline, then the responsibility is not at all the maintenance worker. Because our country does not stipulate that the floor drain must be installed, but the downstairs decoration company privately closes the floor drain, and it is necessary to bear some responsibility for a matter, but it is only a secondary responsibility. Finally, it is necessary to find out the specific cause of the pipeline damage, because the pipeline damage is the main cause of this matter, and it is necessary to identify whether it is the improper operation of the maintenance worker or the developer's fault!

There should be no such rule! Many high-rise buildings do not have floor drains in their houses.

I don't think there is, I don't remember this rule.
