The toilet is a common source of unnoticed leaks. Undetected, hundreds of litres of water can be wasted each day. Often leaks occur when the toilet is out of adjustment or parts are worn. To tell if your toilet is leaking:
- Listen carefully to it. If you hear the sound of running water, your toilet is leaking.
- Add food colouring or dye to the toilet tank and wait 20 minutes. If coloured water appears in the toilet bowl, a leak is present. Toilet leaks are not hard to fix, and you can ask for advice at your local hardware store or call a plumber.

These devices can be purchased at your local hardware store and placed under major household appliances, such as dishwashers and washing machines that may spring leaks. The device alerts you as soon as water starts to collect underneath.
