A little leak can go a long way.
Just one leaky loo can waste around 400 litres of water a day. You could save bucket loads on your usage by checking your property for leaks.
First up, let’s verify you have a leak
Find your water meter
If you live in a house, your meter is outside and usually near the front gate or fence. For units and apartments, your meter is connected to the main water meter and it may be near your front door or in a service cupboard. If you're not sure where your meter is, contact your building management or your owner's corporation.
Once you’ve found your meter, make a note of the numbers.
Stop using any water
Turn off all taps and appliances except the stop tap next to the water meter and the toilet.
Wait 10 minutes
Just make sure no one uses any water during that time.
Check your meter again
If the numbers on your water meter have changed or the wheel has moved, you may have a leak. Repeat the test again, just to make sure.
Open the cover of your meter and turn on the screen by putting your finger over the three dots.
Change to the kL/h or M³/h screen by putting your finger over the three dots for three seconds (this should be the second screen setting). This will tell you how many kilolitres or cubic meters per hour is flowing through your meter.

I have a leak; how do I find it?
Leaks aren’t always easy to see. These are the most common culprits.
A leaky toilet can really add up. A trickle can add more than $425 a year to your bill, while a big leak could add $3,000 or more. A good way to check if your toilet is leaking is the paper test:
Place a piece of toilet paper at the back of the toilet bowl.
Make sure the back of the toilet pan is dry (best to wait 30 mins after the last flush).
Leave it there for a few minutes (make sure no one uses the toilet during this time).
If the paper is wet or torn, you may have a leak.
Dripping taps might not seem like a big deal, but they can waste up to 20,000 litres of water per year or 55 litres a day—that’s roughly $25 extra each bill.
If you notice a tap dripping, the most likely cause is a worn washer, which you may be able to replace yourself.
Unexplained wet patches in your garden can indicate a fault or leak with your irrigation system.
These are generally located on rooftops. It’s normal for a small amount of water to drip from the pipe when in use. But if you see water running down the roof even when the system is turned off, or a wet patch appears on an internal ceiling or wall, you may have a leak.
Hot water units
The most common problem with hot water systems is that the Pressure Temperature Relief Valve (PTRV) can malfunction and release water.
As hot water services are generally located on the side of a house (where people normally don’t walk) these leaks can go undetected for ages. To check for a leak, simply find your hot water unit and see if there is water running out of the pipe.
Faulty automatic top-ups for your water tank or swimming pool
These can malfunction and overflow without you even knowing it. It's a good idea to check these regularly to make sure they're working properly and not wasting precious water.
If you can't locate the leak, you may have a break in your water pipes.
