INSTALLATION INSTRUCTIONS
MAINTENANCE INSTRUCTIONS
1. Dig hole for hydrant approximately 2 feet in diameter and
deeper than the bury depth.
2. Flush gravel, debris, etc. out of supply line before connecting
hydrant.
3. Install hydrant with drain hole below frost line.Use wrenches
on supply line fitting and brass valve body only. This avoids
over tightening the hydrant assembly which could affect
operation.
4. If supply line to the hydrant will not support hydrant, use
re-bar, length of pipe or other suitable support driven in
bottom of pit to help
excavation, turn on water and check hydrant connection for
leaks.
5. Provisions must be made to allow the water to drain from the
hydrant drain hole each time the hydrant is closed.
(a) If the hydrant is installed inside a structure or concrete
driveway, connect 1/8″copper drain tubing to the drain hole
and dig a remote drain field outside the structure for the drain
pipe to empty into. Without this remote piping drain field, the
water from the hydrant drainage
surface around or near the hydrant and will damage the floor
surface or cause muddy areas around hydrant.
(b) Saturated ground in the hydrant drain field can prevent the
hydrant from draining and may result in freezing. If the area
where the hydrant is located is low lying or has a tendency to
have standing water, a largerdrain field or pit may be required
to provide the hydrant a place to drain.
(c) Fill bottom of pit with ½″gravel to a level about 3″above
brass drain valve body, to insure adequate drainage.
Linkage Adjustment
The adjustment can be made with the water supply on by
tightening the packing nut enough to hold the hydrant closed.
To increase the tension: With the hydrant in a closed position, loosen the set screw in the side
of the pivot. Lift the handle, which should lift the linkage without moving the stem, to the desired location
and reset the set screw.
To decrease the tension: Lift the handle part way open and loosen the set screw in the side of the pivot.
Lower the handle, which should lower the linkage without moving the stem, to the desired location and
reset the set screw.
The handle, at the end of the closing stroke, should "snap" closed.
To adjust the linkage, remove the lower link bolt that connects the lower link to the clevis
assembly. Loosen the set screw in the lower link. Turn the lower link out (counterclockwise) to
increase tension and in to decrease tension. The handle, at the end of the closing stroke, should
ìsnapî closed. Tighten set screw. Install lower link bolt.

PLUNGER REPLACEMENT ON ALL YARD HYDRANTS
1. Shut off water supply to hydrant.
2. Lift handle to open position.
3. Remove handle linkage and handle.
4. Loosen packing nut.
5. Remove head casting using two pipe wrenches, one
on head casting, one on pipe.
6. Remove operating pipe assembly by gripping pipe
with vise grips and prying upward. attach vise
grips to brass stem. Damage to stem may cause
leakage around packing nut.
7. Remove plunger from operating pipe with either pipe
wrenches or vise grips.
8. Install new plunger.
9. Apply a small amount of Silicone grease to plunger to
aid the reinsertion into hydrant. (Do not use petroleum
based grease)
10. Insert operating rod assembly in hydrant using a
mallet or a block of wood. Tap rod assembly until plunger
is seated in the valve body.
11. Reinstall head, handle and linkage.
12. Adjust linkage so handle will snap closed at very end
of closing.
DO NOT
TROUBLESHOOTING LEAKAGE PROBLEMS
1. Rocks or other debris in valve seat, causing plunger
not to seat properly. Remove head and operating rod per
instruction and let the water flow to flush the casing.
Examine plunger for damage and replace if necessary.
Tighten the packing nut as
needed, especially in freezing weather. If water is
allowed to seep up around the stem, it may freeze and
cause the stem to stick.
2. Handle linkage out of adjustment. Handle should
“snap” closed when it is approximately 2″from the head
casting upon turning hydrant off. Adjust linkage as
required.
3. Damaged plunger: Replace with new plunger.
4. Packing nut leakage:

PLUNGER &
When the hydrant is closed, no water is
in the riser pipe or head. The plunger
stops water below the frost line where
freezing can not occur.
CLOSED OPEN - WATER FLOWING
Water flows when the handle is raised.
The plunger is lifted allowing water to
flow and seals the drain hole.
Closing the handle pushes the plunger
down to shut off the water and open the
drain hole. This allows the water in the
head and riser pipe to drain into the
gravel bed. The hydrant is now empty
and cannot freeze.
