• A leak the size of a pinhead can waste 1,362,708 litres per year, enough to fill 12,000 bathtubs to the overflow mark
• A dripping tap/hose bib can lose up to 680 litres a month or 8,170 litres per year.

This test should be conducted for a 30 minute period, during which time no water is being used on the property.

1. A dripping tap/hose bib can lose up to 680 litres a month or 8,170 litres per year.
2. Write down the numbers indicated on the meter at the start of this test.
3. Return to check the meter reading after 30 minutes have passed.
4. If the numbers have not changed, you do not have a leak in your pressurized water system.
5. If the numbers are moving this indicates you have an internal leak and you should contact a licensed plumber to inspect your system.

Record the meter reading and check again after seven days at about the same time. The difference between the first and second reading is your weekly water consumption. Divide by seven to estimate daily usage.
