(B)
Any containment principle backflow preventer required
by rules
3745-95-04
and
3745-95-05
of the Administrative Code shall be installed at a location and in a manner
approved by the supplier of water or the director and shall be installed at the
expense of the water consumer. In addition, any backflow preventer required by
paragraphs (B) and (C) of rule
3745-95-05
of the Administrative Code shall be installed at a location and in a manner
that conforms to the following and is approved by the director as required by

6109.13
of the Revised Code:
(1)
Installed in accordance with the criteria outlined for
orientation in the applicable approval standard in paragraph (A) of this
rule.
(2)
Readily accessible for inspection, testing and
repair.
(3)
Installed to prevent submergence.
(4)
Protected from
freezing. Any provided heated enclosures shall conform to ASSE
1060.
(5)
Not installed within a pit or vault below ground for a
reduced pressure principle backflow prevention assembly or reduced pressure
principle-detector assembly.
(6)
Installed to have
a visible free discharge from a relief port and adequate floor drainage to
handle the discharge from the relief port, if applicable.
(C)
The
water consumer shall maintain any containment principle backflow preventer
required by rules
3745-95-04
and
3745-95-05
of the Administrative Code in proper working order and in continuous
operation.
(1)
The supplier of water shall retain authority over any
containment principle backflow preventer required by rules
3745-95-04
and
3745-95-05
of the Administrative Code.
(2)
The supplier of
water shall see that the tests and inspections required under this paragraph
are made.
(3)
The consumer shall, on any premises on which any
containment principle backflow preventer required by rules
3745-95-04
and
3745-95-05
of the Administrative Code are installed, have thorough inspections and
operational tests made of the backflow preventers at the time of installation
or repair, and as may be reasonably required by the supplier of water or the
director, but in all cases at least once every twelve months. The consumer
shall visually inspect and document that no connection or means of connection
exists between the public water system or a consumer's water system and the
auxiliary water system as required by rule
3745-95-04
of the Administrative Code and interchangeable connections as required by rule
3745-95-05
of the Administrative Code for purposes of this paragraph. These inspections
and tests shall be at the expense of the water consumer and shall be performed
by a person approved by the supplier of water and acceptable to the director as
qualified to inspect and test backflow preventers.
(4)
Backflow
preventers shall be repaired, overhauled or replaced at the expense of the
consumer whenever they are found to be defective.
(5)
Records of such
inspections, tests, repairs and overhauls shall be kept by the consumer and
made available to the supplier of water.
(6)
The supplier of
water shall maintain a paper or electronic record documenting the survey,
investigation and installation of containment principle backflow preventers.
The supplier of water shall maintain documentation of inspections, tests,
repairs and overhauls related to the containment principle backflow preventers
and that no connection or means of connection exists between the public water
system or a consumer's water system and the auxiliary water system required by
rules
3745-95-04
and
3745-95-05
of the Administrative Code for a minimum of five years.
(D)
The
supplier of water shall inspect or cause to be inspected all installations
where an approved connection exists between an auxiliary water system and the
public water system or a consumer's water system at least once every twelve
months and shall maintain an inventory of all such installations and inspection
records. Such inventories and inspection records shall be made available during
sanitary surveys and at other reasonable times. Paper or electronic inspection
records shall be maintained by the supplier of water for a minimum of five
years.
(E)
Containment principle backflow preventers approved by
the supplier of water and conforming to prior or subsequent editions of the
standards cited in paragraph (A) of this rule, and which are properly
maintained in accordance with paragraph (C) of this rule shall be excluded from
the requirements of paragraphs (A) and (B) of this rule if the supplier of
water and the director are assured that the backflow preventer will
satisfactorily protect the public water system. When containment backflow
preventers are replaced, the backflow preventers shall meet the requirements of
paragraphs (A) and (B) of this rule at the time of
installation.
(F)
For single property community water systems and
noncommunity water systems, other backflow preventers for plumbing applications
may be accepted by the director to abate or control the cross connection, if
the water use practice is not specifically addressed in this chapter, and the
backflow preventer is identified as an approved isolation backflow prevention
device in accordance with section 608 of rule 4101:3-6-01 of the Administrative
Code adopted by the board of building standards for the corresponding water use
practice. The consumer shall ensure these backflow preventers are inspected at
least once every twelve months, maintained in proper working order, tested, if
applicable, and maintain records of the results thereof. This paragraph does
not apply to water use practices posing a severe health hazard or in cases
where an auxiliary water system is on or available to the premises.
