Many people don’t know you can test your toilet for a secret leak in three easy steps and in less than 20 minutes.
1. Put 10 drops of food coloring in the tank.
2. Don’t flush for 15 minutes.
3. If the colored water shows up in the bowl, you have a leak.
Encourage your residents to report leaks as soon as they are spotted. If leaks are happening more and more, it’s time to consider new toilets or retrofitting your current hardware.
