The water meter “spins” to register how much water your household is using. A quick test you can do is turn off all taps inside the house and make sure nothing is dripping. Now go outside and have a close look at your water meter. Is it still moving? If so, you could possibly have a leak or burst pipe. A more accurate test is to do this test overnight when you know no one is using the water. Take a close photo of the meter before you go to bed and one as soon as you wake up. Have the numbers increased? If so, call Koalafied Plumbing to put an end to it.
