backflow preventer may be installed subject to full static pressure.
(3)Â
Devices of all types. Backflow and backsiphonage preventing
devices shall be accessibly located, preferably in the same room with
the fixture they serve. Installation in utility or service spaces
is also permitted, provided that they are readily accessible.
F.Â
Protective devices required. Approved devices to protect
against backflow and backsiphonage shall be installed at all fixtures
and equipment where backflow and/or backsiphonage may occur and where
a minimum air gap cannot be provided between the water outlet to the
fixture or equipment and its flood-level rim.
(1)Â
Connections not subject to back pressure. Where a
water connection is not subject to back pressure, a vacuum breaker
shall be installed on the discharge side of the last valve on the
line serving the fixture or equipment. A list of some conditions requiring
protective devices of this kind is given in the table below, entitled
"Cross-Connections Where Protective Devices Are Required and Critical
Level (C-L) Settings for Vacuum Breakers." NOTE: "Critical level"
(C-L) is defined as the level to which the vacuum breaker may be submerged

the Superintendent may require the use of an approved reduced-pressure
backflow preventer. A partial list of such cross-connections which
may be subject to back pressure is as follows:
[Amended 8-28-2001 by L.L. No. 6-2001]
G.Â
Double check-double gate valves. The Superintendent
may authorize installation of approved double check double valve assemblies
with test cocks as protective devices against backflow in connections
between a potable water system and other fluid systems which present
no significant health hazard in the judgment of the Superintendent.
H.Â
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.
I.Â
Maintenance requirements.
(1)Â
General requirements. It shall be the responsibility
of building and premises owners to maintain all backflow presenters
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.
(2)Â
Reduced-pressure backflow preventers. Periodic testing
and inspection schedules shall be established by the Village for all
reduced-pressure backflow preventers, and the interval between such
testing and inspections and maintenance service of each device shall
be established in accordance with the age and condition of the device.
Inspection intervals should not exceed one year, and maintenance service
should not exceed five years. These devices shall 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 when approved by
the Village. Testing shall be conducted by a state-certified inspector,
and the devices shall bear an inspection certification tag indicating
the date of inspection and the name and address of the plumber who
conducted such inspection.
[Amended 8-28-2001 by L.L. No. 6-2001]
The Village shall give notice of violation in
writing to the owner or authorized agent of the owner of the building
or premises in which a violation of this Part 3 is found. The Village
shall set a reasonable time, not exceeding 120 days, for the owner
to have the violation removed or corrected. Upon failure of the owner
to have the defect corrected by the end of the specified time interval,
the Village may, if in its judgment an imminent health hazard exists,
cause the water service to the building or premises to be terminated
and/or recommend such additional fines or penalties to be invoked
as herein may be provided.
[Amended 12-17-1991 by L.L. No. 8-1991; 8-28-2001 by L.L. No. 6-2001]
Any owner or authorized agent of the owner responsible for the maintenance of the plumbing systems in the building who violates any provision hereof or knowingly permits a violation to remain uncorrected after the expiration of time set by the Village shall, upon conviction thereof, be required to pay a fine of $250 for each violation. Each day of failure to comply with the requirements of this Part 3 after the specified time provided under § 168-77 shall constitute a separate violation.
[Added 8-28-2001 by L.L. No. 6-2001]
Should any section or provision of this chapter
be adjudged as invalid by any court of competent jurisdiction, such
judgment shall not affect, impair or invalidate any other part of
this chapter or the remainder thereof but shall be confined in its
operation to only that section or part thereof directly or necessarily
involved in the controversy in which such judgment shall have been
rendered.
