The easiest and most cost-efficient way to test the accuracy of a meter is to conduct a bucket test. To conduct a bucket test, first, turn off all water sources within and outside the home. Open the meter box and take a manual read of the meter. If you are unable to open the meter box lid easily, you can purchase a water meter box key at any hardware store. When opening the meter box, please make sure to do so slowly and carefully, as the City’s Advanced Metering Infrastructure (AMI) equipment is generally mounted to the bottom of the meter box lid and is connected via a wire to the meter register.
Next, fill a 5-gallon bucket with water from your home. Return to the meter and verify that the read increased by only 5 gallons. If only 5 gallons are measured, the meter is measuring accurately.
