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 ® is connected.
2. Remove the three pipe plugs on the side of the
FloodSafe ® and install the test cocks provided
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.

TEST LOWER CHAMBER
5. Connect the test pipe to test cock A in the lower
chamber as shown in Figure 4. A quick-
disconnect 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.
