ARTICLE II. WATER* Page 9 of 19 (1) Devices shall be installed as close as practical to the customer's service connection and shall be installed above grade in an accessible location approved by the department. (2) Devices shall have at least the same cross -sectional area as the water meter. In those instances where it is determined that a continuous water supply is necessary, two (2) sets of devices shall be installed in parallel. Where parallel devices are required, the sum of the cross -sectional areas of the devices shall be at least equivalent to the cross - sectional area of the meter. (E) Maintenance, testing, and records. (1) The customer shall test and service such devices at least once a year and immediately after installation, relocation or repair. A report, in a form acceptable to the department, which sets forth the results of such test(s) shall be filed immediately with the department. The department may require a more frequent testing schedule if it is determined to be necessary and all costs shall be borne by the customer. (2) Devices shall be serviced, overhauled or replaced whenever they are found to be defective and all costs of such service, overhaul or replacement, including testing, repair and maintenance shall be borne by the customer. (3) The department will supply affected customers with a list of persons acceptable to the department to test devices. (4) The department will notify affected customers by mail when annual testing of a device is needed. Failure to notify shall not relieve the customer of the obligation to test and service its devices. (F) Backflow prevention device removal. (1) The department must be notified and approval must be obtained from the department before a device is removed. (a) Removal in general.

(b) Removal for relocation. A device may be relocated following confirmation by the department that the relocation will continue to provide the required protection to satisfy installation requirements. A retest will be required, prior to return to service, following the relocation of the device. (c) Temporary removal for repair. A device may be removed for repair or service, provided water use is either discontinued until repair is completed and the device is returned to service, or the service connection is equipped with backflow protection approved by the department. A retest will be required, prior to return to service, following the repair or service of the device. (d) Temporary removal for replacement. A device may be removed and replaced provided water use is discontinued until the replacement device is installed. All replacement devices must be approved by the department prior to being put into service and must be commensurate with the degree of hazard involved. A retest will be required, prior to return to service, following the replacement of the device. (G) Water system survey. (1) Plans and specifications must be submitted to the department upon request for review of possible cross -connection hazards for new or existing service connections.
