Malfunction of the drain mechanism
Water leaks from the tank. This problem may occur if the drain mechanism or gaskets that are responsible for the tightness of the washing of the flush to the tank came out of the system. In the first case, turn off the water supply and replace the float mechanism. In the second case, wait for the water to completely merge from the toilet, unscrew the mount from the toilet to the tank and change the gasket.
