Section 4.7 D shall be modified to read as follows, and Section E and F, shall be added as
follows:
D. Retrofit Of Existing Systems This applies to an existing fire protection system
which is being modified, extended, or enlarged. Such systems include a
modification or extension to an existing network such as (distribution piping,
sprinkler heads, control valves, etc. are added to an existing system), or where an
additional fire protection system (new feed line, riser, control valve, distribution
piping, sprinkler heads, etc.) is added to an existing system. If any of the
conditions are met the system will be required to be upgraded to meet minimum
standards
E. The installation of properly sized assembly may cause an excessive pressure loss in
some altered Class 1 and 2 systems. Such loss could make the system
noncompliant with NFPA Pamphlets 13 and 14 as adopted. The Responsible
Managing Employee shall document to the Approving Authority that reasonable
modifications will not compensate for the additional loss. The documentation shall
contain a listing of the minimum flow and pressure, headloss summary, desired and
calculated sprinkler head output and a summary of the options examined to reduce
headloss. For these installations, if not already installed, the existing cross
connection control device will be replaced with two check valves in series (one of
which can be the alarm valve), each valve meeting AWWA C508-82, UL 312-88,
• or UL 193-88, or the latest versions thereof, and equipped with a resilient seating
surface. The valves or adjacent piping shall be equipped with a sufficient number
of resilient seated test cocks (minimum diameter of one quarter to one-half inch) to
determine the effectiveness of each valve (there shall be no leakage past any check
valve). Sufficient resilient seated isolation valves - one valve upstream of the
valves and one valve downstream of the valves - shall be present or added to the
system to permit this testing.
F. Existing Systems Existing fire protection systems, which have no single check
valves or alarm valves are required to meet the minimum standards for a Class 1
and 2 fire protection system. The minimum protection for cross connection
control for existing systems is the same as listed for new systems, except for
existing systems which have a minimum of a single check valve. The check valve
must have 2 resilient seated test cocks installed, one up stream and one
downstream of the valve to determine the effectiveness of the valve. The
performance testing of the check valve shall be preformed at intervals
predetermined by the Approving Authority. Should a check valve fail during any
performance test, it will automatically be subject to upgrade to meet the minimum
for protection requirements.
9
Existing fire protection systems which have a Class 4, 5, or 6 rating must have at a
minimum a DRPZA installed on either the main riser or it can be installed on the
chemically effected section of the piping system.
Section 4.8 CONSUMER RESPONSIBILITIES shall be modified to read as follows:
The consumer shall:
A. Eliminate all cross connections or install an approved backflow prevention
assembly on the water service line.
B. Immediately correct any malfunction of the backflow prevention assembly.
C. Inform the Approving Authority of any proposed or modified cross connections
and of any existing cross connections of which the consumer is aware.
D. Submit construction plans for approval, and install an approved backflow
prevention assembly. Failure, refusal, or inability on the part of the customer to
install, maintain, and have tested, any backflow prevention assembly on the
consumer's property shall constitute grounds for discontinuing water service
until such requirements have been satisfactorily met.
E. Have the type of backflow prevention assemblyand
manner of installation
approved by the Approving Authority.
F. Install a backflow prevention assembly if a private water source is operational even
if it is not cross connected to the Water System.
G. Install two (2) backflow prevention assemblies in parallel if uninterrupted water
service is desired during testing or repair.
H. Not install a by-pass around any backflow prevention assembly unless there is a
backflow prevention assembly of the same type in the bypass.
I. Have a certified operational test within 10 days of installation. All RPZA's,
DCVA's, PVBA's, DRPZA's, and DDCVA's will be tested at intervals not to
exceed one (1) year after installation and annually there after. In those instances
where the Approving Authority deems the degree of hazard to be great, an
operational test may be required at more frequent intervals.
I
10
J. Have only personnel licensed by the Arkansas State Health Department accomplish
repairs, installation, maintenance and testing of backflow prevention assemblies.
Assemblies for fire protection lines tapped from a domestic service line shall meet
the same criteria. Repairs shall be made immediately upon notification by the
tester. Overhaul shall be accomplished at intervals not to exceed five (5) years.
Section 5.1 BACKFLOW PREVENTION ASSEMBLIES shall be modified to read as
follows:
Only those assemblies that are approved by BWU shall be used for backflow
prevention in water service lines.
A. Approved Assembly: Assemblies that have been tested and approved by the
