Water meters are positive displacement devices. They cannot register usage unless water under pressure flows through them. If you feel your meter is malfunctioning, it can be flow-tested for accuracy by written request. The current fee is $25.00 plus $100.00 meter installation fee, but can vary based on meter size. If the meter should fail the flow-test, a new meter will be installed at no expense to the customer, and the $125.00 will be refunded. If, however, the meter tests out to be accurate, the $125.00 fee will stand.
