Installation, Operation & Maintenance Instructions for the

PRIER C-634 Heavy Commercial Wall Hydrant

*Please leave this sheet for the property owner*

Thank you for purchasing the PRIER C-634 Heavy Commercial Wall Hydrant, the nest quality commercial

hydrant available. Your C-634 will provide you years of dependable service with little or no maintenance.

Please note: Your 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.

Installation:

Installation procedures may vary slightly depending on the seat option purchased and the installation inlet options. The
C-634 wall hydrant is available with the following inlet options:

N 1” MIP x 3/4” FIP
P 1” Male SWT x 3/4” Female SWT
V 3/4” ProPress Ready

*P and V inlets only available with CC length

1. Determine the location for the installation of the hydrant. Ensure there is adequate
work room in the interior of the structure for securing the hydrant to the plumbing
piping. Bore a 1 1/8” diameter hole through the wall in the desired position for the
installation and a 1/4” hole that is 1/2” deep.

2. The PRIER C-634 is designed for installation in either the horizontal or vertical
position. If using vertical installation, it is recommended that the hydrant be installed
with the hose threads in the “up” position. Refer to the drawings below.

3. If you are planning to solder the connection, be certain the hydrant is in the fully
open position to prevent seat damage from the heat.

4. 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.

5. After the water supply connection is made, secure the hydrant to the structure.

Operation:

Operation of the C-634 Commercial Wall Hydrant is a simple process. Water ows through the hydrant after turning the
loose key one full turn counter-clockwise to the “on” position. The hydrant will achieve maximum ow at 2 1/2 full turns.

Turn off the hydrant by turning the loose key clockwise to the “off” position.

The hydrant will drain for a few moments. If the dripping persists after a few moments, tighten the key slightly until the
dripping stops. Be careful not to overtighten the hydrant.

The C-634 incorporates an integral atmospheric anti-siphon vacuum breaker that, in the rare occurrence of a back siphon­age, opens to the atmosphere preventing contamination of the water supply.

As well as an atmospheric vacuum breaker, the C-634 incorporates vacuum breaker check valve in the rare case that
water is forced backwards into the valve.

Maintenance:

The C-634 Heavy Commercial Wall Hydrant leaves the factory fully air tested and operational. It is treated with an FDA

approved lubrication. The hydrant requires no scheduled maintenance to provide long life. If the stem is removed, the

bypass O-Ring needs to be replaced and lubricated with an FDA approved lubricant to avoid tearing.

*ALWAYS REMOVE HOSE DURING FREEZING TEMPERATURES*
