After the toilet bowl was flushed, there would always be a strange sound when the float reached the highest point. At the same time, the water would stop filling. Why? It sounded like a low, strange cry that had never been heard before.

Answer 1

This was a common scenario in toilet flushing, known as the "water seal."

Water seal was a technique that formed a layer of water film in the pipe to prevent the liquid from flowing in the pipe while maintaining the water level in the pipe. When the toilet is flushed, the float will stay at the highest point at the bottom of the toilet. At this time, the water seal will prevent water from flowing out of the toilet and maintain the water level in the toilet.

When the strange sound appeared and the water stopped pouring, it might be because the water seal had been tightly sealed in the pipe and could not continue to pour water. This usually happens when the water in the water seal has been used up or the water seal has been damaged.

It should be noted that in reality, the water seal of the toilet bowl is usually made of plastic or rubber. It cannot withstand the influence of environmental factors such as high temperature or pressure. Therefore, if there is any problem in the pipeline, it may cause the water seal to rupture or be damaged, causing the water in the toilet to leak.
