If the Equa-Balance® seal was not the reason for service -

Step 3: Replacing the Equa-Balance® Seal
Remove the current Equa-Balance® seal (21). Check
seal for damage (punctures, rips, etc.). Replace damaged

Step 8: Replacing the Internal Operating Assembly
There is a flat or a V-notched boss inside of the hydrant
head (1) that keeps the operating coupling (7) from rotating
when hydrant is turned on and off. With operating screw

until it stops, and making sure that a flat side or corner
of operating coupling (7) lines up with appropriate boss,
reinsert the internal operating assembly into the hydrant.
Step 9: Replacing the Faceplate
Insert nozzle (17) into place and fasten the faceplate (18) to
