Water meters are positive displacement devices. They cannot register usage unless water under pressure flows through them. Water meters fail by slowing down and eventually stopping. 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.
