§ 50.35 DEFINITIONS.
   For the purpose of this subchapter, the following definitions apply unless the context clearly indicates or requires a different meaning.
   AIR GAP. The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture, or other device and the flood-level rim of the receptacle.
   APPROVED. Accepted by the Municipal Water and Sewer Department as meeting an application specification stated or cited in this subchapter, or as suitable for the proposed use.
   AUXILIARY SUPPLY. Any water source or system other than the potable water supply that may be available in the building or premises.
   BACK-SIPHONAGE. Backflow resulting from negative pressures in the distributing pipes of a potable water supply.
   BACKFLOW. The flow of water or other liquids, mixtures, or substances into the distributing pipes of a potable supply of water from any source or sources other than its intended source. Back-siphonage is one type of BACKFLOW.
   BACKFLOW PREVENTER. A device or means to prevent backflow.
   CHECK VALVE. A self-closing device which is designed to permit the flow of fluids in one direction and to close if there is a reversal of flow.
   CROSS-CONNECTION. Any physical connection between a potable water supply and any unapproved source or system through which backflow can occur. Furthermore, it is any potable water supply outlet which is submerged or can be submerged in wastewater and/or any other source of contamination. See definitions of BACKFLOW and BACK-SIPHONAGE.
   DRAIN. Any pipe that carries wastewater or waterborne wastes in a building drainage system.
   FIXTURE, PLUMBING. Installed receptacles, devices, or appliances supplied with water or that receive or discharge liquids or liquid-borne wastes.
   FLOOD-LEVEL RIM. The edge of the receptacle from which water overflows.
   HAZARD, HEALTH.
      (1)   Any conditions, devices, or practices in the water supply system and its operation which create, or, in the judgment of the Public Works Manager, may create, a danger to the health and well-being of the water consumer.
      (2)   An example of a HEALTH HAZARD is a structural defect in the water supply system, whether of location, design, or construction, that regularly or occasionally may prevent satisfactory treatment of the water supply or cause it to be polluted from extraneous sources.
   HAZARD, PLUMBING. Any arrangement of plumbing including piping and fixtures whereby a cross-connection is created.
   HYDROPNEUMATIC TANK. A pressure vessel in which air pressure acts upon the surface of the water contained within the vessel, pressurizing the water distribution piping connected to the vessel.
   MANAGER. The Public Works Manager of the village.
   OUTLET. 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.
   POLLUTION. The presence of any foreign substance (organic, inorganic, radiological, or biological) in water that tends to degrade its quality so as to constitute a hazard or impair the usefulness of the water.
   REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTER. An assembly of differential valves and check valves, including an automatically opened spillage port to the atmosphere designed to prevent backflow.
   SURGE TANK. The receiving, nonpressure vessel forming part of the air gap separation between a potable and an auxiliary supply.
   VACUUM. Any pressure less than that exerted by the atmosphere.
   VACUUM BREAKER, NONPRESSURE TYPE. A vacuum breaker designed so as not to be subjected to static line pressure.
   VACUUM BREAKER, PRESSURE TYPE. A vacuum breaker designed to operate under conditions of static line pressure.
   WATER AND SEWER DEPARTMENT. The Village Water and Sewer Department.
   WATER, NONPOTABLE. Water that is not safe for human consumption or that is of questionable potability.
   WATER, POTABLE. Water free from contaminants in amounts sufficient to cause disease or harmful physiological effects. Its bacteriological and chemical quality shall conform to the requirements of the federal and state drinking water regulations and to any regulations of the public health authority having local jurisdiction.
