Mystery Case File:
Are there water leaks in your home? Undetected leaks can waste thousands of gallons of water every month.
Your Mission:
- Help your family use water wisely by checking your toilet for leaks
- Investigate where there are leaks elsewhere in your home
- Report your findings to Leak Detection Headquarters!
Step 1:
Use 10 drops of food coloring or a toilet dye strip/tab to check your home’s toilets for leaks. You may need a grown-up to help you with this part! Here’s how:
- Remove the toilet tank lid.
- Drop 10 drops of food coloring into the toilet tank. Then put the lid back on the tank. Do not flush!
- Wait 20 minutes.
- Check your toilet bowl. If you see colored water, you have a leak. If not, you don't.

Step 2:
Fixing leaks should be left to grown-ups, but you can help by using your detective skills to find leaks around your home.
Check the places marked with a water drop in the picture to find common leaks (sinks, toilets, showers, bathtubs, washing machines, dishwashers, water heaters).
Share what you have found with a grown-up. Then proceed to Step 3!
Step 3:
Report your leak detection findings to Headquarters. They'll give you details on your next water-saving mission!
