Follow these steps to conduct a simple leak detection test:
Step 1: Ensure that no water is being used in your house (turn off all water appliances, such as washing machines and dishwashers).
Step 2: Record the black and red numbers on you meter last thing at night.
Step 3: The next day, record your water use first thing in the morning.
Step 4: If the red numbers have changed, the test confirms there is a leak and further investigation is needed.
