Toilet tank leaks waste water and cause higher water bills. If you suspect your toilet tank is leaking, a simple do-it-yourself home toilet leak test can detect if your toilet tank is leaking water into your toilet bowl.
Following these steps to test if your toilet tank has a leak:
Step 1: Remove the toilet tank lid and add a small amount of red food coloring to the tank’s water.
Step 2: Replace toilet tank lid and do not use toilet for at least an hour.
Step 3: After an hour, check to see if the water in your toilet bowl has any signs of the red dye. If it does, then the water in the tank is continuously leaking into the toilet bowl. Be sure to flush and clean your toilet immediately following the test to prevent dye stains.
