supply, provided that, except in the event of an emergency, with respect
to the inspection of any residential dwelling or dwelling unit, consent
to such inspection shall first be obtained from a person of suitable
age and discretion therein or in control thereof.
C.
Entrance onto premises. The owner, lessee or occupant
of every such dwelling, building, structure, enclosure or premises
shall give the Director or his designated agent free access thereto
for the purpose of performing his duties under this Article. It shall
be unlawful to refuse entrance or impede anyone authorized under this
Article from entering, inspecting, examining or testing the plumbing
system in such building or premises at all reasonable times upon the
display of proper identification.
D.
No liability. Except as may otherwise be provided
by statute, local law or ordinance, no officer, agent or employee
of the village charged with the enforcement of this Article shall
render himself personally liable for any damage that may accrue to
persons or property as a result of any act required or permitted in
the discharge of his duties under this Article. No person who institutes
or insists in the prosecution of a criminal proceeding under this
Article shall be liable for damages hereunder unless he acted with
actual malice and without reasonable grounds for believing that the
person accused or prosecuted was guilty of an unlawful act or omission.
As used in this Article, the following terms
shall have the meanings indicated:

A.
General. A potable water supply system shall be designed,
installed and maintained in such manner as to prevent contamination
from nonpotable liquids, solids or gases from being introduced into
the potable water supply through cross-connections or any other piping
connections to the system.
B.
Cross-connections prohibited. Cross-connections between
potable water systems and other systems or equipment containing water
or other substances of unknown or questionable safety are prohibited
except when and where, as approved by the authority having jurisdiction,
suitable protective devices such as the reduced pressure zone back-flow
preventer or equal are installed, tested and maintained to ensure
proper operation on a continuing basis.
C.
Interconnections. Interconnection between two or more
public water supplies shall be permitted only with the approval of
the Nassau County Department of Health.
D.
Individual water supplies. Cross-connections between
an individual water supply and a potable public supply shall not be
made unless specifically approved by the health authority having jurisdiction.
E.
