How to test a leaking toilet tank
A leaking toilet tank can easily run your home's water bill, while keeping them unnoticed. The loss occurs when the plug on the top of the toilet begins to deteriorate, which limits its ability to retain water in the toilet tank above. Because the water in the toilet is diverted outward, you will never notice an increase in the water level in the container, and the leak may be slow enough so that it is not visible. Instead of calling a plumber to determine if the toilet tank has a leak, there is a test that allows you to detect leaks of yourself. Performing the test itself takes approximately 15 minutes, requires a common element of the house and allows you to avoid hiring a plumber to inspect the toilet.

Instructions
1 Lift the tank lid up and out of the tank. Place it on a solid and sturdy surface that will prevent it from falling and potentially breaking.
2 Remove any bathroom cleaners that may affect the color of the water. Pull the chain to ensure that the water in the tank is clear.
3 Apply the dyes with the water in the upper tank. Alternatively, if you do not have food coloring, use fruit juice powder or instant coffee. Make sure the water in the tank is a deep color, not clear.
4 Allow the toilet to sit for approximately 15 to 30 minutes. Do not let anyone use the toilet during this time.
5 Look at the water in the toilet after the allotted time has elapsed. If there is any dye in the toilet bowl, the toilet tank leaks.
