Field Testing Procedures (Continued)
Restore Operation
After testing restore all valves to their original positions.
Note: This is a suggested typical test method. Check with your
local code for approved test procedures in your area.
Testing with the FEBCO Test Kit
The FEBCO Test Kit includes gauge, complete with hoses, fit-
tings, adapters and laminated instructions in a compact plastic
case. The FEBCO Test Kit includes a differential pressure gauge
used to test all approved Reduced Pressure Assemblies including
the FEBCO Models 825Y, 825YA, 825YD Reduced Pressure
Assemblies and the 826YD Reduced Pressure
Detector Check.

Test for the 826YD
This device is tested with the same procedure as the Model
825YD. However, the bypass 825Y 3/
4
" valve must be isolated
from the mainline valve using the 3/
4
" ball valves during the test
and tested separately.
Proper Bypass Operations
Flow 3 GPM through the bypass by opening the mainline test
cock #4. Use the flow meter for this measurement (1 gallon flow
in a 20 second time period). After the flow rate has been set, col-
lect the discharge flow in a container for 20 seconds. The volume
of water collected should be one gallon.
