The comparison determines deterioration of system
performance or condition and the need for further testing or
maintenance.
Monthly:
.1 Inspection of gauges (water supply and system
pressure) to ensure good condition and normal water
supply pressure.
.2 Flow Control valve shall be externally inspected. The
valve inspection shall verify the following:
a. The gauges indicate normal supply water pressure is
being maintained.
b. The valve is free of physical damage.
c. All valves are in the appropriate open or closed position.
d. There is no leakage from the alarm drains.
Quarterly:
- Alarm Device (pressure or flow switch).
(
Testing by opening the inspector's test connection
)
- Main Drain Test (Riser Flow Test) to determine if change
in water supply or control valve position.
Test procedure:
-
Record the pressure indicated by the supply water
gauge.
-
Fully open the main drain valve.
-
Record residual pressure.
-
Close the main drain valve slowly.
-
Record the time taken for supply water pressure to
return to the original pressure.
-
Open the alarm control valve
Semi-Annually:
- Valve supervisory switch shall be tested to verify the
operation of the switch upon movement of the hand
wheel.
Annually:
-
Manual Pull station test.
-
Record indicating the date of the last trip, tripping time
and name of organization conducting the test shall be
maintained at a location available for review by the
Authority Having Jurisdiction.
Every 5 years:
- Alarm valve and associated strainers, restriction orifice,
gaskets, moving parts shall be inspected internally.
- Test on gauge (gauge precision required: less than 3%
of the full scale)
- Test on control valves operation
