Before applying the color in the toilet bowl, mark the original water level in the bowl where it is always supposed to be.
Apply a few drops of the color in the toilet bowl. Once done, flush the toilet with full pressure. Now, wait for at least one hour to ensure that the toilet bowl has cracked. Because when the crack or leak is too thin, it will take enough time to drop the water level.

If you find water, check if it has color to ensure the bowl is cracked. If you can identify there is colored water, it means the toilet bowl slowly loses water because of the cracked toilet bowl.

To check this, turn on all the faucets and then flush the toilet. If the vent can’t pass the air properly, while passing water in the drains, it will sound like gargling.
