If you suspect you have a toilet leak on your hands, you're probably wondering which area of your toilet contains the source of the leak. Well, you'll be pleased to know that locating a toilet leak can be a very simple undertaking, particularly with a handy set of instructions. Read on to learn everything you'll need to know.

Step 1 - Determine the Most Likely Area for the Leak

If you're dealing with a toilet leak, the leak is either emanating from your toilet tank or your toilet bowl. After making an educated guess as to which part contains the source of the leak, you'll be ready for the next step.

Step 2 - Apply Your Food Coloring

Now that you've chosen an area, apply your food coloring to the perceived source of the toilet leak. If you suspect the toilet leak is emanating from your tank, apply ten droplets of food coloring after carefully removing the tank's lid. If you suspect your bowl to be the source of the leak, apply 20 droplets, as the bowl contains more water.

Step 3 - Wait it Out

After applying your food coloring, wait for about an hour, then carefully inspect the area directly beneath the leak's perceived source for any signs of food coloring. If you find some, your question is answered. However, if no food coloring can be spotted, you should repeat the second step with the part of the toilet you initially chose not to test.
