Water leaks account for approximately 12% of all water use in the average American home, and the toilet is one of the most likely places to find them.
Sometimes it is easy to tell that your toilet is leaking - you hear the sound of running water or a faint hissing or trickling. But many times, water flows through the tank silently, which is why these leaks are often overlooked.
- Remove the toilet tank lid.
- Drop one dye tablet or 10 drops of food coloring into the tank. (Dye tablets are often available for free through local water providers).
- Put the lid back on. Do not flush.
Wait at least 10-15 minutes, and then look in the bowl. If you see colored water, you have a leak. If not, you don't.
