High volume water leaks often come from toilets. Toilet leaks are often silent which makes them hard to detect, and are usually caused by a worn or misaligned part. A toilet that continues to run after flushing could be wasting 20 – 40 litres per hour - that's 175,000 to 350,000 litres per year, enough water to fill a swimming pool!
To check for a toilet leak, use a dye tablet,* food colouring, juice crystals or instant coffee. Carefully remove the toilet tank lid. Place a dye tablet (or alternative) in the tank. Wait about 10 minutes without flushing. After 10 minutes, check the water in your toilet bowl. If the water is coloured, you've got a leak.
The leak may be due to an old or worn-out toilet flapper that can be easily replaced – learn how. Some toilet repairs may require the assistance of a plumber.
