The sewer of the 28-story building reaches the underground garage. If I live on the second floor, how can I avoid sewer blockage as much as possible?

It seems that the sewer pipes from the first floor of the high-rise building to the underground garage are all cast iron. In order to avoid the blockage of sewer pipes, we should try not to forget to throw toilet paper and ladies' long hair in the toilet. At the same time, we should negotiate with the property management company to clear the sewer pipe in the basement on time within one or two months.

I hope you can adopt.
