After I flush my toilet I notice a small yet constant trickle of water that comes out of the rim hole closest to the tank.
I've replaced the flush valve, tank gasket and overflow valve. I then did the food coloring test where you put a few drops of food color in the tank to check for leaks and I didn't get any color in the bowl.
This trickle of water will last for about two or three hours then finally stop.
Has anyone seen this before or have any suggestions?
