NOTES:
1Critical level (C-L)
is defined as the level to which the vacuum breaker may be submerged
before backflow will occur. Where the C.L is not shown on the preventer,
the bottom of the device shall be taken as the C.L.

(5)
Connections subject to back pressure. Where a potable
water connection is made to a line, fixture, tank, vat, pump or other
equipment with a hazard of back-flow or back siphonage where the water
connection is subject to back pressure and an air gap cannot be installed,
the installation of an approved reduced-pressure-principle backflow
preventer shall be required. A partial list of such connections is
shown in the following table, Partial List of Cross-Connections Which
May Be Subject to Back Pressure.

G.
Double check - double gate valves. The Board may authorize
installation of approved double check - double gate valve assemblies
with test cocks as protective devices against backflow in connections
between a potable water system and other nonhazardous substances which
would not endanger the health of the consumer but would be a nuisance
if introduced into the public water supply system.
H.
Low-pressure cutoff required on booster pumps. When
a booster pump is used on a water pressure booster system and the
possibility exists that a positive pressure of 10 pounds per square
inch or less may occur on the suction side of the pump, there shall
be installed a low-pressure cutoff on the booster pump to prevent
the creation of a vacuum or negative pressure on the suction side
of the pump, thus cutting off water to other outlets.
A.
General requirements. It shall be the responsibility
of building and premises owners to maintain all backflow preventers
and vacuum breakers within the building or on the premises in good
working order and to make no piping or other arrangements for the
purpose of bypassing backflow devices.
B.
Backflow preventers. These devices should be inspected
frequently after the initial installation to assure that they have
been installed properly and that debris resulting from the installation
has not interfered with the functioning of the device. The testing
procedures shall be in accordance with the manufacturer's instructions
and in compliance with all local, state and federal requirements.
Testing shall be conducted by a backflow prevention device tester
certified by the New York State Department of Health, and the devices
shall bear an inspection certification tag indicating the date of
inspection and the name and address of the backflow prevention device
tester who conducted such inspection.

A.
Notification of violation. When a violation of this
article is found, the Board or its administrative official, if so
appointed, shall notify, by written notice, the owner of the property,
as indicated on the then-current Village tax roll.
B.
Notice requirements.
(1)
The notice shall identify the sections of the article
that have been violated and the basis for the notice of violation.
(2)
The notice shall inform the owner that, should he
disagree with the conclusion as to the violation, he shall have seven
calendar days from receipt of the notice, or a shorter time period
determined by the Board of Trustees or the Superintendent of the Village
Water Department, to file a written request at the Village Hall for
a hearing on the matter before the Village Board of Zoning Appeals.
The Board or Superintendent may set a shorter time if the Board or
Superintendent determines that exigent circumstances exist, threatening
the health, safety or welfare of Village residents.
(3)
The notice shall inform the owner that if he does
not request a hearing and he fails to cure the violation within seven
calendar days of the receipt of the notice, or a shorter time period
determined by the Board of Trustees or the Superintendent of the Village
Water Department, the agents of the Village Water Department shall
have the right, but not the duty, to enter onto such owner's land
to perform the testing required. The Board or Superintendent may set
a shorter time period if the Board or Superintendent determines that
exigent circumstances exist, threatening the health, safety or welfare
of Village residents. In any event, the curing of the violation shall
be at the expense of the owner of the land. If the agents of the Village
Water Department perform the testing required, a fee of $250 will
be due and owing to the Village from the property owner. In the event
that the owner fails to pay the Incorporated Village of Old Westbury
$250 within 30 days after demand therefor is sent to the last address
for the owner indicated on the then-current Village tax roll, the
fee of $250 shall be added to the property's November water assessment.
(4)
The notice shall be given by personal delivery to
the person to be served; be given by personal delivery to a person
of suitable age and discretion at the dwelling place of the person
to be served and by first-class mail to the person to be served; or
be given by registered mail, return receipt requested, at the last
known address of the person to be served.
C.
Notwithstanding the foregoing, if in the Board's judgment
a health hazard exists, the Board may cause the water service to the
building or premises to be terminated.
D.
Fines. The owner or authorized agent of the owner responsible for the maintenance of the plumbing systems and use of water on the premises or in the buildings thereon who knowingly permits a violation of any of the provisions of this article to remain uncorrected after the expiration of the time period set forth in the notice issued pursuant to Subsection B above shall, upon conviction by the court, be subject to and required to pay a fine of not in excess of $250 for each violation, and each day of failure to comply with the requirements of this article after the expiration of the time period set forth in the notice issued pursuant to Subsection B above shall constitute a separate violation.
