Z1315 Service Guide
Step 1: Shutting Off the Water Supply to the Hydrant
Locate the supply shut-off valve and rotate until water supply is off.
Step 2: Removing the Face Nut and Adjacent Components
Using crescent wrench or 1-1/2 inch open-end wrench, remove the face nut
(4) from head (1) by turning counterclockwise.
Step 3: Removing the Internal Operating Assembly
The internal operating assembly (5-8 and 10-12) can be removed by gripping
the square end of the operating screw (5) with a pair of pliers and pulling
straight out.
If the operating screw O-Ring was not the reason for service – skip to step 5.
Step 4: Replacing the Operating Screw O-Ring
Remove the operating screw (5) from operating coupling (7) by turning
clockwise and slip the old O-Ring (6) off, and replace with new O-Ring (6).
Reinstall operating screw (5) into operating coupling (7) by turning counter-
clockwise. (Note: Lubricate the operating screw (5) threads and the O-Ring
(6) with Lubriplate FGL-2 if needed.)
If the hydrant shutoff washer was not the reason for service – skip to step 8.
Step 5: Replacing the Hydrant Shutoff Washer
Remove #10-24 NC x 3/8 screw (12) using a flat screwdriver and turning
screw (12) counterclockwise, remove washer (11) and replace with new
washer (11) and new screw (12) turning screw clockwise until tight.
Step 6: 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 (5) turned counterclockwise into operating coupling
(7) 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 7: Replacing the Face Nut
Insert face nut (4) into head (1), and rotate clockwise until hand tight, then
using a crescent wrench or 1-1/2 inch open end wrench, snug nut (4) tight.
Step 8: Turning On the Water Supply
Locate the water supply shut-off valve and rotate until water supply is on.
