3 steps to test your toilet for leaks

Leaky toilets can waste the most water in the home. Most leaks are silent, but signs of a toilet leak may include a hissing sound, continual water running, or flushing on its own.

Does your toilet have the runs? Flush out leaks with the leaky toilet test!

TEST IT
Drop food colouring or leaky toilet test strip in your toilet tank. Wait 15 minutes without flushing.
CHECK IT
Check the water in your toilet bowl. If the water is coloured, you’ve got a toilet leak!
FIX IT
Most leaks are caused by a worn out flapper. They’re inexpensive and as easy to replace as a lightbulb.
