Purpose
Jefferson Lab performs flow tests of
the public
main on site to ensure its continuous operation. Planned testing ensures irregularities
are detected and the risk of deficiencies within the system is mitigated
through maintenance.
This testing procedure is conducted in
accordance with accepted standards, codes, and manufacturers' recommendations.

5.0 Conduct the Test
5.1
Attach
a gage cap to the No. 1 hydrant, which is located along Hogan Drive (on the
north side of Jefferson Lab).
5.2
Open
the No. 1 hydrant and record its static pressure (in both psi and kPa).
5.3
Move
to the No. 2 hydrant, which is also located along Hogan Drive (west of the No.
1 hydrant).
5.4
Remove
the caps from the No. 2 hydrant.
5.5
Measure
the diameter of the outlets on the No. 2 hydrant, which are square and sharp.
5.6
Replace
one cap on the No. 2 hydrant.
5.7
Open
the No. 2 hydrant and record its Pitot reading (in both psi and kPa).
5.8
Return
to the No. 1 hydrant and record the residual pressure (in both psi and kPa).
5.9
Shut
off the water flow at the water-supply connection near the No. 1 hydrant.
5.10
Shut
down the No. 2 hydrant slowly and carefully.
5.11
Replace
all caps to the No. 2 hydrant.
5.12
Return
to the No. 1 hydrant and record the static pressure (in both psi and kPa). The
pressure should be equal to what was measured at the start of the test.
5.13
Shut
down the No. 1 hydrant.
5.14
Remove
the gage cap and replace it with the regular cap.
