Installation, Operation & Maintenance Instructions for the
PRIER C-633/C-634 Commercial Wall Hydrant
Please leave this sheet for the property homeowner
Thank you for purchasing the PRIER C-633/C-634 Commercial Wall Hydrant, the finest quality commercial
hydrant available. Your C-633/C-634 will provide you years of dependable service with little or no maintenance.
Please note: Your C-633/C-634 hydrant has drain holes under the packing nut. After shutoff, the drain holes will
allow water to drain for a few moments to prevent freezing. This is normal and according to design.
1. No special installation tools are required. Determine the location for installation of the hydrant. This valve
is designed for installation in either horizontal or vertical position. If installing vertically, install with hose
connection in “up” position.
2. Using the template provided on the box, bore a 1-3/8” diameter hole through the wall in the desired position,
and a ¼” alignment hole that is ½” deep.
3. Insert the hydrant through the hole and secure it to the inside wall using the provided wall clamping ring.
Seal through wall penetration if required.
4. Flush all foreign particles from the water line before connecting the hydrant.
5. Connect the water supply piping to the hydrant as desired. With a closed-end hose on the valve creating
back pressure, test the installation for leakage.
6. If planning to solder the hydrant to the supply piping, open the hydrant to the full open position before
soldering. Excess heat to the valve will damage the sealing surfaces on the stem of the hydrant.
INSTALLATION
Installation procedures may vary slightly depending on the seat option purchased and the installation inlet
options. The C-633/C-634 wall hydrant is available with the following inlet options:
Inlet Style
Inlet Specifications
N
1” MPT x 3/4” FPT
P
1” Male SWT x 3/4” Female SWT
V
3/4” ProPress Ready
C-634 AND C-633NCC (Straight)
*P and V inlets not available on C-633NSV model
1. No special installation tools are required. Determine the location for
installation of the hydrant. This valve is designed for installation in either
horizontal or vertical position. If installing vertically, install with hose
connection in “up” position.
2. Using the provided template, Bore two holes through the wall and remove
the excess material between those to create an opening for the swivel inlet of
the valve.
3. Align your rotating inlet to the supply piping and secure the valve to the
outside wall. Seal through wall penetration if required.
4. Flush all foreign particles from the water line before connecting the hydrant.
5. Secure the hydrant to the supply piping and test for leakage with a closed-
end hose as described above.

:
5
. Flush all foreign particles from the water line before
connecting the Freezeless Hydrant. Foreign particles
may clog the vacuum breaker/backflow preventor caus-
ing it to fail.
6
. Insert the Freezeless Hydrant through the previously
bored hole and secure the hydrant to the inside of the
wall with the provided wall clamping ring.
7
. Secure the Freezeless Hydrant to the supply piping.
Test the installation for leakage.
1
. Determine the location for installation of the Freeze-
less Hydrant. Be sure there is adequate work area on
the interior of the structure for securing the Freezeless
Hydrant to the waterline.
3
. Using the template provided on the box, bore a 1
3
/
8
”
diameter hole through the wall in the desired position,
and a
1
/
4
” hole that is
1
/
2
” deep.
2
. The Prier C-634 is designed for installation in either
horizontal or vertical position. If using vertical installa-
tion, it is recommended that the hydrant be installed with
the hose threads in the “up” position. Refer to drawings
to the right for correct installations.
4
. If planning to solder the Freezeless Hydrant to the
supply piping, remove the operating stem before apply-
ing heat to the valve. Heating the valve will damage the
sealing surfaces on the stem of the Freezeless Hydrant
O
PERATION
:
The operation of a Prier C-634 Freezeless Wall
Hydrant is simple. The Freezeless Hydrant will
begin to flow at about 1 full turn of the key and will
achieve maximum flow at 2
1
/
2
full turns.
After shutoff, the hydrant will drain water from be-
hind the packing nut. If the water drains for more
than 1 minute, the stopper may need to be replaced.
Do not overturn when opening or closing the hydrant!
M
AINTENANCE
:
The Prier C-634 Freezeless Wall Hydrant requires no
scheduled maintenance for long wear life. If the op-
erating stem is removed, replacement of the O-Ring
on the worm sleeve and worm drive is recommended.
