OPERATION, MAINTENANCE AND INSTALLATION
INTRODUCTION
This manual will provide you with the information to
properly install, maintain and ensure a long service
life for the FloodSafe

contamination of the potable water system due to
flooding and malicious tampering as described in
ASSE Standard 1063. The FloodSafe

pipeline operation to allow full airflow in both
directions. The float check(s) will rise and seal when
the surrounding atmosphere is filled with water.

RECEIVING AND STORAGE
Inspect the FloodSafe
shipment. Unload all devices carefully to the ground
without dropping. Remove all blocking material
inside of the metal basket.
The devices should remain boxed, clean and dry
until installed to prevent weather related damage.
For long term storage greater than six months, the
rubber seat should be coated with a thin film of FDA
approved grease such as Lubriko #CW-606. Do not
expose rubber seat to sunlight or ozone for any
extended period.
DESCRIPTION OF OPERATION
The FloodSafe
lower chamber and upper, redundant chamber. Both
chambers contain identical float checks that are
open during normal pipeline operation and allow full
airflow in both directions. If flooding occurs the
lower float check will rise, preventing floodwater from
reaching the outlet of the air valve and subsequently
the pipeline. If the lower float check fails the upper,
redundant float check will close preventing
floodwater from reaching the air valve. The basket
screen prevents debris from interfering with the
operation of the FloodSafe

standard connection practices. The bolting for 6"
and larger devices conforms to ANSI B16.1 for class
125# flanges. An optional mounting bracket (80)
may be used to mount the device to wall supports.
Flanged connections should only be mated with flatfaced pipe flanges equipped with full-face or ring
type resilient gaskets. The bolts should be tightened
in gradual steps using the crossover method.

TROUBLESHOOTING
Several problems and solutions are presented below
to assist you in troubleshooting the FloodSafe
efficient manner.
Air valve water discharge: It is normal for air
valves to discharge some water before closing.
Continuous leakage requires maintenance of
the adjacent air valve.
Leaks during field test: Clean and inspect the
resilient seats and the float checks.

DISASSEMBLY
WARNING:
Close the isolation valve underneath the
adjacent air valve. Failure to close the isolation
valve may allow discharge of air into the
FloodSafe
Note: If the FloodSafe is connected to the optional
mounting bracket (80), the FloodSafe™ will need to
be removed from the bracket.
1. Remove the basket (12).
a) On sizes with side taps, use an allen wrench
b) On sizes without the side taps, use an open-
2. Remove the lower chamber (1B) by removing
the bolts (7A) and nuts (7B) joining the two
chamber halves.
The FloodSafe® chambers may be heavy.

and away from the chamber.
end wrench to remove the bolts holding the
basket to the lower chamber flange.
CAUTION:
3. Remove the seat (4) by pulling it upward and out
of the chamber. Tilt the chamber to remove the
float check (5).
4. The upper chamber is removed in the same
manner as the lower chamber. Remove the
bolts joining the chamber and cover using care
to support the chamber. The seat and float
check can be removed in the same manner as
before.
REASSEMBLY
All parts must be clean. Worn or damaged parts
should be replaced during reassembly.
1. Install the float check (5A) into the chamber
(1A).
2. Insert the seat (4A) with the raised circular
surface facing down into the chamber (1A).
3. Connect the upper chamber (1A) to the cover (2)
with the bolts (7A) and nuts (7B) using the cross
over method. One washer is installed under the
head of the bolt and one underneath the nut.
4. Install the float check and seat into the lower
chamber per steps 1 and 2.
5. Connect the lower chamber (1B) to the upper
chamber (1A) by using the bolts (7A) and (7B).
One washer is installed under the head of the
bolt and one underneath the nut.
6. Install the basket (12) to the lower chamber (1B).
a) On sizes with the side taps, start the socket
head cap screws into the lower chamber
flange. Install the basket by pushing upward
and turning clockwise. Tighten the socket
head cap screws to secure the basket.
b) On sizes without the side bolts, install the
bolts through the bottom flange and into the
tapped holes on the basket screen. One
washer is used underneath the head of the
bolt.

FIELD TESTING THE FLOODSAFE
The FloodSafe® inflow preventer should be tested
after installation, and periodically thereafter as
recommended by the local authority having
jurisdiction, but at least annually.
For field testing, a testing kit available from the
manufacturer is required consisting of test cocks and
a test pipe that can be used for multiple installations.
ISOLATE DEVICE
1. Close the isolation valve under the adjacent air
valve with which the FloodSafe
2. Remove the three pipe plugs on the side of the
FloodSafe
with the test kit.
3. Remove the basket screen by loosening the
screws and twisting the screen. Clean the
basket if needed.
4. Block the bottom port with the expandable plug
provided in the kit. Open the three test cocks A,
B, and C.
®
and install the test cocks provided
Figure 4: Field Test Piping
®
is connected.
TEST LOWER CHAMBER
5. Connect the test pipe to test cock A in the lower
chamber as shown in Figure 4. A quickdisconnect coupling is provided to facilitate the
assembly.
6. Fill the clear test pipe and lower chamber with
clean water by pouring water into the test pipe
and maintain the water level above the
“Minimum Test Level” for 5 minutes while
observing test cock B for leakage. The water
level in the tube may drop due to leakage in the
fittings, bottom plug, or as air escapes between
the float and the seat (acceptable). The device
shall be rejected and repaired if water is
observed from test cock B during the 5 minute
test period.
TEST UPPER CHAMBER
7. Close test cock A. Move the test pipe up to the
upper chamber test cock B. A quick-disconnect
fitting under the clear pipe will aid in its removal.
8. Fill the clear test pipe and upper chamber with
clean water by pouring water into the test tube
and maintain the water level above the
“Minimum Test Level” for 5 minutes while
observing test cock C for leakage. The device
shall be rejected and repaired if water is
observed from test cock C during the 5 minute
test period.
9. If one of the initial tests fail and repairs are
made, a “Final Test” shall be conducted and
recorded. Repairs typically consist of removing
the chamber bolts and cleaning the float and
cleaning or replacing the rubber seat.
RETURN TO SERVICE
10. When the tests are complete, open test cock A
and drain the water and remove the test piping
and bottom plug. The test cocks may be left in
the device, but all three must to be closed.
11. Re-assemble the basket screen to the lower
chamber. Tighten the screen bolts.
12. IMPORTANT: Open the isolation valve underneath
the air valve that was closed in step 1.
