The meter must be attached to a fire hydrant with a minimum of a double detector check valve by use of the provided hydrant spanner wrench, not a pipe wrench. Water flow must be controlled by the gate valve on the meter, not the hydrant valve. The meter must be secured at all times. If the meter is lost or stolen, it is the customer's responsibility to file a police report and contact Hesperia Water District promptly. A new meter will not be issued until a police report number is provided, along with applicable fees and deposits.
