There should be no problem. Of course, if it is a large kitchen, there will be that kind of stir-fry method of burning fire in the pot, and sometimes there is a section of metal pipe.
Generally, it is wrapped with rubber skin, hugged with a hoop, and then covered with glass glue for temporary treatment. To be firm, change both sides of the cast iron pipe and PVC to flanges, and then lock them. Note that the PVC side should be added with steel sheets.
Hehe, it's definitely okay, it's just overkill, because the requirements and price of the water supply pipe itself are higher than the drainage pipe, and the price is much higher than the drainage pipe.
It's a PVC telescopic pipe, neutral glass glue is fine, and the whole interface is sealed.
Generally use PVC material - this is the most widely used material at present!
