Definitions.
As used in this
				  section:
(1) "Air gap" means the unobstructed
				  vertical distance through the free atmosphere between the lowest opening from
				  any pipe or outlet supplying water to a tank plumbing fixture, or other device,
				  and the flood level rim of the receptacle. The vertical physical separation
				  shall be at least two times the inside diameter of the water inlet pipe above
				  the flood rim level but shall not be less than one inch;
(2) "Air vent type backflow preventer" means
				  a device containing two independently operating check valves separated by a
				  chamber which can automatically vent to the atmosphere if backflow
				  occurs;
(3) "Atmospheric vacuum
				  breaker" means a mechanical device which automatically air vents a pipeline to
				  prevent backsiphonage;
(4) "Double
				  check valve assembly" (DCVA) means a device which contains two independently
				  acting check valves located between two tightly closing shutoff valves and
				  fitted with properly located test cocks;
(5) "Fire sprinkler system" for fire
				  protection purposes means an integrated system of underground and overhead
				  piping designed to provide fire protection for a building or structure. The
				  installation includes one or more automatic water supplies. The portion of the
				  sprinkler system above-ground is a network of specially sized or hydraulically
				  designed piping installed in a building, structure, or area generally overhead,
				  and to which sprinklers are attached in a systematic pattern. The valve
				  controlling each system riser is located in the sprinkler riser or its supply
				  piping. Each sprinkler system riser includes a device for actuating an alarm
				  when the system is in operation. The system is usually activated by heat from a
				  fire and discharges water over the fire area;
(6) "Hose bibb vacuum breaker" means an
				  atmospheric vacuum breaker designed to be attached to an outlet having a hose
				  connection thread;
(7) "Owner"
				  means the customer of a public water system;
(8) "Pressure vacuum breaker" means a device
				  which contains a spring loaded check valve and a spring loaded atmospheric vent
				  which opens when the pressure approaches atmospheric. The unit shall include
				  two tightly closing shut-off valves located at each end of the device and two
				  test cocks properly located for testing the device;
(9) "Reduced pressure principle backflow
				  preventer" (RPD) means a device containing within its structure a minimum of
				  two independently acting, approved check valves, together with an automatically
				  operating pressure differential relief valve located between the two check
				  valves. The first check valve reduces the system pressure a predetermined
				  amount so that during normal flow and a cessation of normal flow the pressure
				  between the checks shall be less than the system pressure. In case of leakage
				  of either check valve, the differential relief valve, by discharging to
				  atmosphere, shall operate to maintain the pressure between the checks less than
				  the system pressure. The unit shall include tightly closing shut-off valves
				  located at each end of the device and each device shall be fitted with properly
				  located test cocks;
(10) "Siamese
				  connection" means an inlet equipped with one or more couplings to which a fire
				  hose can be attached and through which water can be delivered by a fire
				  department pumper to a sprinkler system; and
(11) "Toxic or objectionable substance" means
				  any compound which could affect the public health, the potability, or the
				  aesthetic quality of the water.
