Does water in a toilet tank flow backwards into the pipe? Seek help?

Under normal circumstances, the water in the toilet tank does not flow back. Because the pressure rod in the tank will automatically crush the valve when the water is full, preventing backflow.

However, if the toilet bowl has been used for a long time, the valve is easy to break if it has been used for too long. At this time, if the water is stopped, or the water pressure fluctuates greatly, the water supply pipe is empty, but there is water in the water tank of the flush toilet, when the water supply is restored again, the moment the valve or faucet is opened, the instantaneous negative pressure will be generated in the water supply pipe, resulting in a strong suction, and the water in the water tank will flow back into the water supply pipe.
