Step 1. How to check for leaks...
Check for a hidden (concealed) leak
Turn off all taps, the washing machine, dishwasher and irrigation at your property.
Read your water meter and write down or take a photo of the numbers (including the red numbers, which indicate litres). Make sure you leave the water meter tap on.
Wait at least one hour before reading your water meter again - remember not to use any water, even to flush the toilet during this time.
If the reading has changed (last numbers or dial on the water meter), you may have a water leak. Please contact a licensed plumber to investigate.
Please note: the numbers on a water meter will only move if water is being drawn through it, either by something on your property (hose, washing machine, plumbed in fridges, dishwashers, etc.) or if there is a leak.
