Backsiphonage means the flowing back of used, contaminated or polluted water from a plumbing fixture or vessels or other sources into a water supply pipe due to a negative pressure in such pipe.

Barometric loop means a loop of pipe rising approximately thirty-five (35) feet, at its topmost point, above the highest fixture it supplies.

Check valve means an automatically operated device which is designed to permit the flow of fluids in one (1) direction and to close if there is a reversal of flow.

City water means any water which, according to recognized standards, is safe for human consumption as purified and transported by the parish water systems.

Contamination. See "pollution."

Cross-connection means any physical connection or arrangement between two (2) otherwise separate piping systems, one (1) of which contains potable water and the other water of unknown or questionable safety, steam, gases or chemicals whereby there may be a flow from one (1) system to the other. See "backflow" and "backsiphonage."

Inlet means the open end of the water supply pipe through which the water is discharged into the plumbing fixture.

Plumbing system includes the water supply and distribution pipes, plumbing fixtures and traps: soil waste, and vent pipes; building drains and building sewers, including their respective connections, devices and appurtenances within the property lines of the premises, and water-treating or water-using equipment.

Reduced pressure principle backflow preventer means an assembly of differential valves and check valves including an automatically opened spillage port to the atmosphere designed to prevent backflow.

Surge tank means the receiving, nonpressure vessel forming part of the airgap separation between a potable and an auxiliary supply.

Vacuum means any pressure less than that exerted by the atmosphere.

Vacuum breaker, nonpressure type means a vacuum breaker which is designed so as not to be subjected to static line pressure.

Vacuum breaker pressure type means a vacuum breaker designed to operate under conditions of static line pressure.

Water potable means any water which, according to recognized standards, is safe for human consumption.
