§ 20-140.3. Installation, maintenance and repair of devices.

A.

In order to effectively protect the drinking water system, all backflow prevention devices must be maintained in a safe and reliable operating condition. The customer shall be responsible for the continued maintenance of all backflow prevention devices on his/her premises.

B.

Installation, maintenance, testing and repairs shall be performed by one of the following:

1.

A qualified specialist trained and certified by the University of Florida T.R.E.E.O. Center Backflow Prevention Technician Training Institute or FWPCOA certified.

2.

A manufacturer's representative.

3.

A City of South Daytona Public Works Department employee.

C.

Installation, maintenance and repair of all backflow prevention devices affecting automated fire sprinkler systems must be performed by a specialist qualified to work on said fire systems.

D.

Test, maintenance and repairs of backflow prevention devices shall be conducted on the following backflow prevention devices:

1.

Double Check Valve Backflow Prevention Device—A double check valve backflow prevention device (as distinguished from a dual check valve) shall be inspected and tested initially upon installation and thereafter at least annually.

2.

Reduced Pressure Zone (RPZ) Backflow Prevention Device—This device shall be tested and inspected at the time of installation and at least annually thereafter. In addition, the bottom of differential relief valve must be at least 18 inches above the 100 year flood level. Because of this latter requirement and the potential for damage to the device due to possible accident, tampering or freezing weather, consideration should be given to locating the RPZ inside of protective structure or buildings.

3.

Synthetic Components Within a Device—These should be replaced according to a schedule recommended by the manufacturer of the backflow device. Generally, components should be replaced every five years or sooner.

E.

Records of the initial installation, subsequent repairs and maintenance (including regularly scheduled testing) shall be maintained by the customer for a minimum of three years preceding the current year. Records of installations, annual testing and maintenance are to be submitted to the Chief Building Official for review and a second copy furnished to the Public Works Director. If records are not made available upon request or are found to be substantially incomplete, the customer shall be required to immediately have the device serviced and tested by a qualified technician and a record of such test submitted to the Chief Building Official and Public Works Director.

F.

All backflow prevention devices and maintenance records shall be subject to periodic inspection by the Chief Building Official and the Public Works Director. If a device is found to be inoperative or malfunctioning, the customer will be given 30 days to complete the corrections required. If at the end of the allotted time, satisfactory corrections have not been made, notice will be given that the water service will be terminated after seven days from receipt unless the customer completed the corrections. At the end of that seven day period the water service will be terminated if satisfactory corrections have not been completed.
