As used in this local law, the following terms shall
have the meanings indicated:
AIR-GAP SEPARATION
A physical break between a supply pipe and receiving vessel.
The air gap shall be at least double the diameter of the supply pipe,
measured vertically above the top rim of the vessel and in no case
less than one inch.
APPROVED CHECK VALVE
A check valve that seats readily and completely. It must
be carefully machined to have free-moving parts and assured watertightness.
The face of the closure element and valve seat must be bronze composition
or other noncorrodible material which will seat tightly under all
prevailing conditions of field use. Pins and bushings shall be bronze
or other noncorrodible, nonsticking material, machined for easy, dependable
operation. The closure element (e.g., clapper) shall be internally
weighted or otherwise internally equipped to promote rapid and positive
closure in all sizes where this feature is obtainable.
APPROVED DOUBLE-CHECK-VALVE ASSEMBLY
An assembly of at least two independently acting approved
check valves, including tightly closing shutoff valves on each side
of the check valve assembly and suitable test cocks plus connections
available for testing the watertightness of each check valve.
APPROVED REDUCED-PRESSURE-PRINCIPLE BACKFLOW PREVENTION DEVICE
A device incorporating two or more check valves and an automatically
operating differential relief valve located between the two checks,
two shutoff valves and equipped with necessary appurtenances for testing.
The device shall operate to maintain the pressure in the zone between
the two check valves, less than the pressure on the public water supply
side of the device. At cessation of normal flow, the pressure between
the check valves shall be less than the supply pressure. In case of
leakage of either valve, the differential relief valve shall operate
to maintain this reduced pressure by discharging to the atmosphere.
To be approved, these devices must be readily accessible for maintenance
and testing and installed in a location where no part of the device
will be submerged.
APPROVED WATER SUPPLY
Any water supply approved by or under the public health agency
of the State of New York, the County of Ulster or the Highland Water
District. In determining what constitutes an approved water supply,
the Department of Public Health of the State of New York (herein called

the same management and for the same purpose.
PROTECTIVE DEVICE
Any of the following devices:
(2)
Approved reduced-pressure-principle backflow
prevention device.
(3)
Approved double-check-valve assembly.
SERVICE CONNECTION
The terminal end of a service connection from the district
water supply at its point of delivery to the consumer. If a meter
is installed, "service connection" means the downstream end of the
meter. No unprotected takeoffs from the service line ahead of any
meter or backflow protective device located at the point of delivery
to the consumer shall be permitted.
