Installation Guide
Yard Hydrant
PFAF Series
CAUTION:
Use wrench on inlet valve body and fittings only!
CAUTION:
If the hose is attached to nozzle of hydrant when hydrant is shut
off, back siphoning can occur if end of hose is left in container of liquid. The
end of hose must be left open to the air so hydrant can drain back. Under no
circumstances should PROFLO yard hydrants drain back into well or drinking
water supply!
Ferguson disclaims all liability of any kind and voids the hydrant warranty for
installations of this product where it can or could drain back into a drinking
water supply.
INSTALLATION INSTRUCTIONS
Installing, adjusting and maintaining PROFLO Yard Hydrant.
INSTALLATION:
1. First be sure water line on which hydrant is to be installed has been thoroughly
flushed to wash out foreign particles. Ferguson will not warrant or accept any
responsibility if the water line is not flushed out prior to attachment of hydrant.
2. Be sure the hydrant is installed with provision for drainage below the frost line.
a. If hydrant is installed in a pit, the pit must have an open bottom or some
form of drainage.
b. If hydrant is buried in the ground, a few tile can be laid in gravel or coarse
material to form a field system for the drain.
c. If hydrant is buried in ground and no tile are used, be sure to put a quantity
of gravel, crushed rock or some coarse material, not sand, around the drain
of the hydrant. This will permit faster and better drainage.
3. IMPORTANT - If hydrant is buried in the ground, it is a good idea to put a brick
or large stone under the hydrant, because when the hydrant drains and this
subsoil becomes wet, it will allow the hydrant to settle and thus put a strain
on the pipe to which it is connected. A brick or stone would carry this weight.
4. To connect the hydrant to the water line, just turn it onto the male thread
connection for which it is intended.
a. CAUTION - When the hydrant is tightened, be careful that it is not tightened
so tightly that the hydrant head or valve body will be screwed further onto
the pipe and thus change the adjustment of the hydrant. If this should
happen, refer to the adjustment section for the proper adjustment.
5. IMPORTANT - Before backfilling the trench, turn on the water. Then turn on
the hydrant by raising the handle to let the water flow. If the hydrant is not
working properly, refer to Adjustment section. Ferguson will not accept any
responsibility for digging up the hydrant if the installer fails to flush out the
water line before attaching hydrant to water line AND to check the hydrant for
proper operation beforebackfilling the trench.
WARNING:
If the ground freezes at or below the bottom of this hydrant, your
warranty is void and damage due to improper installation or act of nature is not
covered by Ferguson.

ADJUSTMENT:
1. The correct adjustment of this hydrant can be checked by raising the lever.
Water should not run through the hydrant until the lever passes the half way
point or horizontal position. When water is flowing through the hydrant it
should shut off when lever comes down to the horizontal point. The last half
travel of the lever in closing the hydrant opens the drain hole. Also in turning
the hydrant on, the first half travel of the lever puts the cup seals in position
to positively close the drain before the water is turned on.
2. Adjusting the plunger in the lower valve body.
a. To lower the plunger assembly into the valve body, take the G-15 bolt out of
the head casting and remove the handle and G-20 draw straps (note: draw
straps are bent inward which applies pressure on the handle when opening
the hydrant). With two wrenches loosen the (2) 9/16" nuts on each side of
the G-25 pivot connector. To lower the plunger, turn the top nut upward,
(only one thread), then tighten the lower nut upward toward the G-25 pivot
connector (or raise the G-25), then tighten top nut.
b. To determine if the water is not draining out the stand pipe, turn the hydrant
on and let the water flow. Then push down the handle to close the hydrant
with a cup of water covering the nozzle. If the water in the cup siphons
back through the hydrant, the plunger is in the correct position. If the water
does not siphon out of the cup, then adjust the plunger in the same way
as stated in (a). Then check to see if the water siphons out of the cup after
adjustment.
MAINTENANCE:
1. In maintenance, nothing is needed - But, a few drops of oil occasionally on the
cam of the lever will prolong its life.
2. If the hydrant should ever need a new seat washer - it uses a beveled bibb
washer.
3. To replace any valve or plunger parts, NO NEED DIGGING UP HYDRANT - First
turn off water pressure, then simply mark the threads on the pipe by putting
a piece of electrical tape around the pipe just below the hydrant head and
unscrew entire head casting from stand pipe and pull up stem and valve
parts. Remove old plunger and install new plunger onto rod. Then thread head
casting back to same mark on pipe after parts are replaced.
