W34 Yard Hydrant
1. Water leaks from the nozzle when the hydrant is off.
•Check the closing force of the handle. If the handle does not
“snap” closed at the end of the closing stroke, see Linkage
Adjustment instructions.
•If the hydrant leaks just after installation, the valve seat may be
fouled with debris, such as small rocks. The operating pipe
assembly will have to be removed and the hydrant casing
flushed. See Operating Pipe Assembly Removal instructions.
•To inspect and/or replace the plunger if it is worn or damaged,
see Operating Pipe Assembly Removal instructions.
2. Water leaks around the brass stem below the handle linkage when
the hydrant is on.
•The packing nut will occasionally need to be tightened to stop a
packing leak. Tighten the packing nut until snug and the leak
stops. Persistent leaks will require a new packing #10101. See
W34 Packing Replacementinstructions.
3. Water leaks from below ground level when the hydrant is on.
•A small leak may be the result of a leak at the drain hole.
Replace the plunger if it is old and worn. See Operating Pipe
Assembly Removal instructions.
•A large leak may be the result of a hole in the pipe casing
caused by electrolysis corrosion. Some soil conditions can cause
premature failure of the pipe casing near the valve body. Brass
pipe is recommended for these conditions. Contact the factory
for details.
4. Hydrant will not drain when shut off.
•Make sure there are no attachments on the nozzle, such as a
hose or vacuum breaker.
•Improper linkage adjustment (not enough tension) may prevent
the hydrant from draining properly. See Linkage Adjustment
instructions
•A poor drain field around the valve body or a blocked drain hole
will prevent drainage. See Yard Hydrant Installation Instructions.

Linkage Adjustment
To increase or decrease handle tension.
If the Handle does not “snap” closed approximately 3”
from the head casting upon turning off the hydrant,
follow the instructions to adjust the linkage and handle
tension.
Linkage adjustment can be made with the water supply
on by tightening the Packing Nut enough to hold the
hydrant closed.
To increase the Handle tension:
•With the Handle in a closed position, loosen the
Set Screw in the side of the Pivot. Fig 1
•Lift the Handle to the desired position and reset
the Set Screw. Fig 2
•The Handle, at the end of the closing stroke,
should "snap" closed against the Head Casting.
Fig 2
To decrease the Handle tension:
•Lift the Handle part way open and loosen the
Set Screw in the side of the Pivot. Fig 3
•Lower the handle to the desired location and
reset the set screw. Fig 4
•The handle, at the end of the closing stroke,
should "snap" closed against the Head Casting.

If rocks or other debris are believed to have settled in
the Valve Bo
dy, causing the Plunger not to seat
properly, follow these instructions for inspecting or
replacing the Plunger:
1. Shut off water supply to hydrant.
2. Loosen the linkage Set Screw. Fig 1
3. Loosen, do not remove, the Packing Nut. Fig 1
4. Remove head casting using two pipe wrenches,
one on head casting and the other on the pipe.
Fig 2
5. Remove operating pipe by gripping pipe with
vice grips and prying upward. DO NOT attach
vice grips to brass stem. Damage to stem
may cause leakage around packing nut. Fig 2
6. Turn on water and allow to flow and flush the
casing.
7. Examine plunger for damage and replace if
necessary. Fig 3
7a Remove plunger from operating pipe with
either pipe wrenches or vise grips.
7b Install new Plunger #10105 - Fig 3
8. Apply a small amount of Silicone grease to
plunger to aid the reinsertion into hydrant. (Do
not use petroleum based grease).
9. Insert operating rod assembly in hydrant using a
mallet or block of wood. Tap rod assembly until
plunger is seated in the valve body.
10. Reinstall head assembly.
11. Adjust linkage so handle will snap closed at very
end of closing. See “Linkage Adjustment”
