Installation Instructions
Series 009 and LF009
2
Indoors – Figure 1
For indoor installations, it is important that the assembly be eas-
ily accessible to facilitate testing and servicing. If it is located in a
line close to a wall, be sure the test cocks are easily accessible.
A drain line and air gap (see literature ES-AG/EL/TC) should
be piped from the relief valve connection as shown, where
evidence of discharge will be clearly visible and so that water
damage will not occur. Therefore, never install in concealed
locations.
Outside – Figure 2
In an area where freezing conditions do not occur, Series 009 and
LF009 can be installed outside. The most satisfactory installation
is above ground and should be installed in this manner whenever
possible.
In an area where freezing conditions can occur, Series 009
and LF009 should be installed above ground in an insulated
enclosure.
Series 009 and LF009 must be installed in an accessible loca-
tion to facilitate testing and servicing. A discharge line should be
piped from the air gap at the relief valve connection making sure
that there is adequate drainage. Never pipe the discharge line
directly into a drainage ditch, sewer or sump. Series 009 and
LF009 should never be installed where any part of the unit could
become submerged in standing water.
It is generally recommended that backflow preventers never be
placed in pits unless absolutely necessary and then only when
approved by local codes. In such cases, a modified pit installa-
tion is preferred.
Parallel – Figure 3
Two or more smaller size assemblies can be piped in parallel (when
approved) to serve a large supply pipe main. This type of installa-
tion is employed where increased capacity is needed beyond that
provided by a single valve and permits testing or servicing of an
individual valve without shutting down the complete line.
The number of assemblies used in parallel should be deter-
mined by the engineer’s judgement based on the operating
conditions of a specific installation.
For parallel valve installations, the total capacity of the assem-
blies should equal or exceed that required by the system.
Annual inspection of all water system safety and control
valves is required and necessary. Regular inspection,
testing and cleaning assures maximum life and proper
product function.

NOTE: Shutoff Valves: When shutoff valves are removed and reassembly is
necessary, the shutoff valve with the test cock is to be mounted on the inlet
side of the backflow preventer.
A. The 009 and LF009 should always be installed in an accessible location to
facilitate testing and servicing (See page 2). Check the state and local codes
to ensure that the backflow preventer is installed in compliance, such as
the proper height above the ground.
B. We recommend a strainer be installed ahead of 009 and LF009 series assem-
blies to protect the internal components from unnecessary fouling.
CAUTION:
Do not install with strainer when backflow preventer is used on seldom-used
water lines which are called upon only during emergencies, such as fire sprin-
kler lines.
Start Up: The downstream shutoff should be closed. Open upstream slowly and
fill valve. When valve is filled, open the downstream shutoff slowly and fill the water
supply system. This is necessary to avoid water hammer or shock damage.
C. Water discharge from the relief valve should be vented in accordance with code
requirements. The relief valve should never be solidly piped into a drainage ditch,
sewer or sump. The discharge should be terminated approximately 12" above
the ground or through an air gap piped to a floor drain.
NOTE: Relief Valve Discharge Rates
The installation of an air gap with the drain line terminating above a floor drain
will handle any normal discharge or nuisance spitting through the relief valve.
However, floor drain size may need to be designed to prevent water damage
caused by a catastrophic failure condition. Please refer to Figure No. 1 for
maximum relief valve discharge rates, size and capacity of typical floor drains.
NOTE: Do not reduce the size of the drain line from the air gap fitting. Pipe full
line size.
D. After initial installation, a discharge from the relief valve opening may occur due
to inadequate initial flushing of pipe lines to eliminate dirt and pipe compounds.
If flushing will not clear, remove the first check valve and clean thoroughly.
NOTE: Periodic relief valve discharge may occur on dead end service applica-
tions, such as boiler feed lines or cooling tower makeup lines due to fluctuating
supply pressure during a static or no flow condition. To avoid this discharge,
install a spring-loaded rubber seated check valve ahead of the backflow assem-
bly to “lock-in”the downstream pressure.
E. Backflow preventers should never be placed in pits unless absolutely neces-
sary and then only when and as approved by local codes. In such cases,
provision should be made to always vent above flood level or for a pit drain to
ensure an adequate air gap below the relief port.
F. It is important that Series 009 and LF009 backflow preventers be inspected
periodically for any discharge from the relief valve which will provide a visual
indication of need for cleaning or repair of check valves. Also testing for proper
operation of the device should be made periodically in compliance with local
codes, but at least once a year or more often, depending upon system condi-
tions.
Relief vent will discharge water when, during no-flow periods, (1) the first check
valve is fouled or (2) the inlet pressure to the device drops sufficiently due to
upstream pressure fluctuations to affect the required operating differential
between the inlet pressure and reduced pressure zone. Otherwise, such relief
(spitting) can occur when the second check is fouled during emergency back-
flow or resulting from a water hammer condition. For troubleshooting guide
send for S-TSG.
NOTE: Special considerations are necessary when testing assemblies
installed on Fire Prevention Systems.
Fire Protection System Installations: The National Fire protection Agency
(NFPA) Guidelines require a confirming flow test be conducted whenever a
“main line”valve such as the shutoff valves or a backflow assembly have been
operated. Certified testers of backflow assemblies must conduct this confirm-
ing test.

push the seat inward and rotate clockwise against the cage.
The seat, spring cage, spring and disc assembly are now
individual components.
NOTE: 3⁄4" M2 modules snap apart.
3. The disc assembly may now be cleaned and re-assem-
bled or, depending on its condition, may be discarded and
replaced with a new assembly from the repair kit. O-rings
should be cleaned or replaced as necessary and lightly
greased with the FDA approved grease. Refer to parts price
list, PL-RP-BPD for more information.
4. Re-assemble the check valve modules. Check modules are
installed in the valve body with the seat facing the valve inlet.
The modules must be securely in place before the retainer
can be replaced. On the 3⁄4" size retainer may have to be tilt-
ed slightly into place. Replace relief valve assembly.

11⁄4" – 2" (32 – 50mm)

1. Remove the four or six relief valve cover bolts while holding
the cover down.
2. Lift the cover straight off. The stem and diaphragm assembly
will normally remain with the cover as it is removed. The relief
valve spring will be free inside the body at this point.
3. The relief valve seat is located at the bottom of the body
bore, and can be removed, if necessary, for cleaning. The
disc can be cleaned without disassembly of the relief valve
module. If it is determined that the relief valve diaphragm
and/or disc should be replaced, the relief valve module can
be readily disassembled without the use of special tools.
NOTE: The disc rubber is molded into the disc holder and is
supplied as a disc holder assembly.
4. To reassemble the relief valve, press the seat firmly into place
in the body, center the spring on the seat, and insert the
cover and relief valve module as a unit straight into the bore.
Press down on the cover to assure proper alignment. Insert
and tighten bolts.
CAUTION:
If cover will not press flat against body, stem assembly is
crooked and damage can result. Realign stem and cover
before bolts are inserted.
NOTE: No special tools required to service Series 009

1. Remove the relief valve assembly as outlined on page 5.
2. Remove the retainer from the body bore. The check valve
modules can now be removed from the valve by hand or
with a screwdriver.
NOTE: The seats and springs of the first and second check
modules are not interchangeable. The heavier spring and
smaller diameter seat belong with the first check module.
3. The check seats are attached to the cage with a bayonet
type locking arrangement. Holding the cage in one hand,
push the seat inward and rotate counterclockwise against
the cage. The seat, spring cage, spring and disc assembly
are now individual components.
4. The disc assembly may now be cleaned and reassem-
bled or, depending on its condition, may be discarded and
replaced with a new assembly from the repair kit. O-rings
should be cleaned or replaced as necessary and lightly
greased with the FDA approved silicon grease. For more
information refer to repair parts price list PL-RP-BPD.
5. Reassemble the check valve modules. Check modules are
installed in the valve body with the seat facing the valve inlet.
The modules must be securely in place before the retainer
can be replaced. Replace relief valve assembly.
NOTE: No special tools required to service Series 009 21⁄2" – 3"
