NOTE: If a change in orientation of the pumper outlet is required after installation, loosen the Traffic

Flange Nuts, lift hydrant slightly and rotate using caution not to damage or displace the O-ring. Re-tighten
Traffic Flange Nuts to 70-90 ft-lb.

F. Test hydrant with line pressure before backfilling. Remove the cap from the top hydrant outlet. Slightly open

the top outlet valve and slowly open the service gate valve to restore water to the hydrant. When all air is
evacuated from the hydrant, water will begin to come out of the top nozzle. Firmly seat top valve. Completely
open gate valve and check for leaks at flanges and seals.

G. Install concrete thrust collar at or near the ground line. Recommended collar dimensions are 8 inches thick and
30” x 30” square. These dimensions are dependent upon soil conditions.

H. Flush the hydrant after installation to remove any foreign material and ensure J-6000 is set in the open
position (assure full flow is achieved)
