Why does the flush toilet tank leak what to do if the toilet tank leaks

Analysis of the causes of toilet tank overflow and solutions: >>>More

You need to make it clear whether it is a leak at the inlet or outlet. If it is a leak at the water inlet, just replace the water inlet pipe, generally the rubber pad is aging, and just changing the gasket can also solve the problem. If it is a leak at the outlet, it means that there is water flowing down the drain from the toilet all the time, then it is that the drain valve in the toilet tank is broken or the rubber mat is stuck with debris. >>>More

This is because the plug did not reset the last time you flushed, and you only need to press it a few more times to hear the plug snap and it won't leak again.

This is the last time you pressed the water for too long, resulting in the plug not reset, you can press it again, just hear the snap sound to reset.

Please describe your problem in detail, preferably with images.
