What should I do if the toilet overflows?

The water is blocked, so find a property to go into the water.

1. The biggest reason for the backwater problem of sewer pipe is that the pipe wall is getting thicker and thicker, so it can't be discharged in time when draining, but it will cause backwater.

2. If the sewer pipe in Palace x * * is blocked, it mostly happens when it rains, especially when it rains heavily. There is a lot of water in the pipeline, which can't be discharged in time, which will lead to the problem of anti-water in the pipeline.
