Section 7. Approved Devices and Installation Thereof: Required Methods ofBackflow
Prevention.
A. New Assemblies. All backflow prevention assemblies required under this ordinance shall
be of a type and model approved by the Oregon Health Division, and shall be installed in accordance
with Oregon Administrative Rules 333-61-0071 Sections (1) through (4), as now existing or later
amended. Suitable pressure-relief devices to prevent damage from thermal expansion shall be
required in conjunction with the installation of all new backflow prevention assemblies.
B. Existing Assemblies. Backflow prevention assemblies installed before the adoption of
this ordinance and which were approved by the Oregon Health Division at the time they were
installed, but are not on the current list of approved assemblies, shall be permitted to remain in service
provided they are properly maintained, are commensurate with the degree of hazard, are tested at
least annually, and perform satisfactorily. When assemblies of this type are moved, or require more
than minimum maintenance or are on services that are modified, changed size or remodeled, they shall
be replaced by assemblies which are on the Oregon Health Division list of approved assemblies.
c. Required Backflow Prevention Methods. The method ofbackflow prevention required
under this ordinance shall at a minimum be commensurate with the degree of hazard which exists, and
not less than the following:
(1) When the substance which could backflow could be hazardous to health, an approved air
gap of at least twice the inside diameter, but not less than one inch, of the incoming supply
line measured vertically above the top rim of the vessel shall be installed, or an approved
reduced pressure backflow (RPBA) assembly shall be installed.
(2) When the substance which could bacldlow is objectionable but does not pose an
unreasonable risk to health, an approved double check valve assembly (DCV A) shall be
installed. An approved double check valve assembly shall be the minimum protection for fire
sprinkler systems using piping material that is not approved for potable water use and lor
which does not provide for periodic flow through during each 24 hour period.
(3) An approved pressure vacuum breaker assembly (PVBA) or an atmospheric vacuum
breaker (A VB) shall be installed where the substance which could backflow is objectionable
but does not pose an unreasonable risk to health and where there is no possibility of
backpressure in the downstream piping. A shutoff valve may be installed on the line
downstream of a pressure vacuum breaker but shall not be installed downstream of an
atmospheric vacuum breaker.
Section 8. Testine Required.
A. When Required. The water user or the owner of the premises where one or more

reduced pressure assembly (RPBA), double check valve assembly (DCV A), or pressure vacuum
breaker (PVBA) have been installed shall have the assemblies tested by a certified tester at least once
per year. Assemblies installed at facilities which pose an extreme health risk and assemblies which
repeatedly fail shall be tested on a more frequent basis as determined by the City. Backflow
assemblies which have been moved or which have been installed shall be tested before use.
B. Malfunctioning Assemblies. Backflow prevention assemblies found not to be
functioning properly shall be promptly repaired by the owner or water user, and failure to do so may
result in the denial or discontinuance of service as provided in this ordinance.
c. Test Procedures and Reports. Tests performed by certified testers shall be in
conformance with procedures adopted under OAR 333-061-0070 (10), as now existing or later
amended. Reports on the tests shall be prepared by the certified tester and copies shall be provided
to the City and to the water user or owner of the premises.

ordinance and subject to the City budget, the City Engineer may authorize administrative subsidies
for the installation of required backflow prevention devices after a finding that such installation will
protect the City water system and will benefit the public interest.
Section 10. Severabilitv. The provisions of this ordinance are severable. If a portion of
this ordinance is for any reason held by a court of competent jurisdiction to be invalid, such decision
