Installation, Operation & Maintenance Instructions for the
PRIER C-534 Self-Draining Anti-Siphon Wall Hydrant
*Please leave this sheet for the property homeowner*
Dear Homeowner,
Your plumbing contractor has selected the nest outdoor faucet
available for installation at your property. The patented design meets
or exceeds plumbing codes regarding anti-siphon and backow pre-
vention, keeping our potable water system safe. What’s more, the
hydrant is self-draining to prevent your pipes from bursting in freez-
ing weather, even if the hose is left attached.
A few important features of your new hydrant are as follows:
Your hydrant has drain holes under the packing nut (behind the han-
dle) that allow the water to drain from the hydrant after shutoff to
prevent freezing. After shutoff, water will drain from behind the pack-
ing nut for a few moments (Figure A). This is normal and according
to design.
If you use a hose nozzle, you should release the pressure from the
hose before shutting off the hydrant (Figure B). As you turn off the
hydrant, the water will drain from under the packing nut as described
above. The backow will sense a backow
condition in the hose and release the water
pressure at the hose threads. This assures
the backow preventor is working properly
(Figure C).
If you have any questions about the instal-
lation or operation of your PRIER freeze-
less hydrant, please call PRIER Customer
Service at 800-362-9055, or contact us
via e-mail at [e-mail]. PRIER has
been manufacturing products for plumbing
systems since 1881! PRIER products have
been purchased by your ancestors and will
be used by your grandchildren.
Upon shutoff, water will drain
from here.

Maintenance:
The C-534 Self-Draining Anti-Siphon 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.
