    I recently replaced the overflow tube and flapper due to intermittent phantom flushing of the toilet. However, after putting a couple of drops of food coloring into the tank, it showed that water is STILL leaking from the toilet to tank. What might be the fundamental issue here? Any help would be much appreciated. I hope I don't need to replace the toilet.

    Pictures of inside your tank, with the tank fully filled and then one of it empty, would help.
    You might have improperly installed the gaskets and seals on the flush valve (which contains the overflow tube).
    There could be a burr or nick on the rim that the flapper seals against, letting water sneak past.
    The chain could be too short.
    The flush handle could be gunked up or rusty where it rotates going through the wall of the tank, so after a flush it cannot return to its correct position.
    Your fill valve could be screwed up in many different ways, trickling water after it should have shut off.

    Thank you for your reply! The water level is normal. The chain is normal. And I placed the dye in the tank water in general and watched it slowly leak into the bowl.

    Thanks for the reply! Out of all the things you listed, I think it could be the fill valve. However, how would the trickling water from the fill valve leak into the bowl unless something was wrong with the flush valve?[/QUOTE]

    I don't believe the dye gets stuck to the flapper or settles on the flapper if that is what you mean. What would it indicate if the dye did go to the flapper? I should also note that it took over 30 minutes for the dye to appear in the toilet bowl, indicating a very slow leak.

    The black hose is about 4-5 inches long. You can see it in the picture below.

    If the leak is being caused by a problem with the gasket or seals under the flush valve, the leak might stop as the seals gradually relax and form themselves to their final shape.
    There could be a small crack or flaw in the plastic of the flush valve.
    Try a different flapper that fits your flush valve.
    Maybe a squishier one will seal better.
    Try feeling the entire rim of the flush valve for any defects, it can be sanded lightly with very fine sandpaper.
    Also, the link that attaches the flapper chain to the flush lever looks to be installed wrong.
    That link looks hung up.
    The squarish fatter end should be hanging off the hole in the flush lever.
    So that big boxy end can move freely as the flush lever goes up and down.
    The end with the opening should be hanging down, with the chain hanging from it.
    Also, sometimes you have to move that link to a different hole on the flush lever, to get the right angle of pull to make the flapper stay properly centered when it drops back down after a flush.

    Thank you for the advice! Do you think it could be that there is a crack in the porcelain of the tank, causing the leak?

    Possibly, but it would need to be just at the edge of the base of the flush valve. Close enough so that any leaking water is channeled to the bowl by the big fat gasket that seals the tank to the bowl. A crack anywhere else would let water out that would find its way onto the floor.
    Try a few different flappers.

    You might not have properly tightened up the big nut that holds the flush valve to the tank.
    Or there was a burr or crud somewhere under the rubber seal, letting water sneak past.

    If it took a half hour for any dye to show up, you are pbly leaking only a few ounces of water a day. Forget about it, it only will cost a dollar a year in water.
    And it might very well seal itself up from minerals and rust eventually.

    Ok, got it. Maybe I should try tightening the big nut some time.
