If your daily water usage is higher than you expect it to be, follow the steps below to check whether you have a leak.


Step 1. Confirm whether you have a leak or not

Close up of meter with numbers

  1. Turn off all water inside and outside (including evaporative coolers and washing machines).

  2. Write down the black and red numbers on your water meter.

  3. Don't turn any water back on for 2 hours (including flushing the toilet).

  4. After 2 hours write down the black and red numbers again.

    • If the numbers have changed, there may be a leak. Go to step 2 below.

    • If they haven't changed, there's no leak, but you may want to find out why your property is using so much water.


Step 2. Find out where the leak is coming from

To find out where the leak is coming from:

  • Look for dripping taps, including washing machine and dishwasher connections.

  • Check your toilet for leaks:

    • Place a few drops of food colour in the tank/cistern.

    • Without flushing it, look for colouring in the toilet bowl.

    • If there is colour in the bowl, your cistern is leaking.

  • Look outdoors for leaks on garden taps, hoses, watering systems, and swimming pools.

  • Check appliances including solar panels, hot water and air conditioners.

These are called 'detectable leaks' and it's your responsibility to fix them. Contact a licensed plumber if you need help.


Step 3. If you can’t find where the leak is coming from

If you can't find the leak yourself, contact a licensed plumber to locate and repair it.

If the plumber confirms that you weren't reasonably able to locate the leak yourself, you may be eligible for a rebate on the cost of repair. Refer to Undetected leaks.
