Did you know that most water leaks are silent? That makes it difficult to know if you have one in your home, and it could be the cause of a higher-than-usual water and wastewater bill. The City of Vaughan is sharing tips to help you detect water leaks before they cost you.

Check your water meter

To test for water leaks on your property, record the number on your water meter before going to bed. Remember, the water meter is typically located in the basement. Then, avoid running sprinklers, appliances or toilets overnight. 

In the morning, check the number on your water meter. If the number has changed, this indicates water has passed through the meter, meaning you may have a water leak somewhere inside or outside your home.

Test your toilets

The most common cause of high water and wastewater bills is toilet leaks. Here’s how to test if you have a leaky toilet:

1. Remove the tank lid from the back of the toilet.

2. Put one dye tablet or five drops of food colouring in the toilet tank at the back. If you don’t have these materials, you can also use Worcestershire sauce or another dark liquid.

3. Close the toilet lid and wait 30 minutes – do not use or flush the toilet during this time. Then look at the water in the toilet bowl. If you see coloured water in the toilet bowl, you may have a leak. If the bowl is clear and all the coloured water remains in the tank, that means the toilet likely doesn’t have a leak.

4. Repeat these steps with every toilet in your home.

5. If you think you have a water leak, call a licensed plumber to investigate and repair it as soon as possible.
