"AUXILIARY WATER SYSTEM OR SUPPLY." Any water supply available to the premises other than the city's public potable water supply.
"BACKFLOW." The undesirable reversal of flow in a potable water distribution system as a result of a cross connection.
"BACKPRESSURE." A pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or any other means that may cause backflow.
"BACKFLOW PREVENTION ASSEMBLY” or “BACKFLOW PREVENTER (BFP)." An assembly that meets the design and performance standards of the American Water Works Association used to prevent a backflow.
"BACKFLOW PREVENTION ASSEMBLY TESTER." A person certified by the University of Florida Certification Program or the Florida Water & Pollution Control Operators Association Program for backflow prevention assembly testers or other FDEP approved programs.
"BACKSIPHONAGE." Backflow caused by negative or reduced pressure in the supply piping.
"CROSS CONNECTION." A connection between a potable water system and any other environment containing other substances in a manner that would allow such substances to enter the potable water system.
"DOUBLE CHECK VALVE ASSEMBLY (DCVA)." The approved double check valve assembly consists of two internally loaded check valves installed as a unit between two shutoff valves with properly located test cocks.
"REDUCED PRESSURE BACKFLOW PREVENTION ASSEMBLY (RPBA)." The approved reduced pressure principle backflow prevention assembly consists of two independently acting approved check valves together with a hydraulically operating, mechanically independent pressure differential relief valve located between the check valves and below the first check valve. These units are located between two shutoff valves as an assembly and equipped with properly located test cocks.
"RESIDENTIAL DUAL CHECK (RDC)." A compact unit manufactured with two independent spring actuated check valves. It is approved by the State of Florida, according to 62-555.360 FAC.
"SERVICE CONNECTION." The terminal end of the public potable water system, i.e., where the city loses jurisdiction and sanitary control over the water at its point of delivery to the consumers' water system. If a meter is installed at the end of the service connection, then the service connection shall mean the downstream end or consumers' side of the meter.
"VACUUM BREAKER, ATMOSPHERIC." An approved vacuum breaker - non-pressure type is designed for use where it will not be subject to static line pressure. It consists of a float check, a check seat and an air inlet port.
"VACUUM BREAKER, PRESSURE (PVB)." An approved assembly which consists of an independently operating internally loaded check valve and an independently operating loaded air inlet valve located on the discharge side of the check valve, with properly located test cocks and shutoff valves attached at each end of the assembly.
"WATER, POTABLE." Water from any source which has been treated to Florida Department of Environmental Protection standards and which has been approved for human consumption. “POTABLE WATER” is water of excellent quality intended for drinking, cooking, and cleansing uses.
