Installation, Operation & Maintenance Instructions for the
PRIER C-144/244 Diamond Series Freezeless Wall Hydrant
Please leave this sheet for the property homeowner
Thank you for purchasing the PRIER C-144/244 Diamond Series Freezeless Wall Hydrant, the finest quality freezeless wall
hydrant available. Your C-144/244 will provide you years of dependable service with little or no maintenance.
1. Determine the location for the installation of the hydrant. The valve must be installed into a heated area of the structure
that won’t drop below freezing. Ensure there is adequate work room in the interior of the structure for securing the hy-
drant to the plumbing piping. Bore the hole size listed above through the wall in the desired position for the installation.
2. All freezeless wall hydrants require a slight downward pitch to aid the draining process of the hydrant once the product
is turned to the “off” position. PRIER has machined an appropriate pitch into the casted backflange to assist and ensure
that a proper drainage pitch results after installation.
3. Position the spout of the hydrant in the downward position. From the interior of the structure, utilize the date code
on the copper pipe near the inlet. When the code is pointed down, the spout is oriented in the proper position on the
outside of the structure.
4. If you are planning to solder the connection (D, S or F style seats), be certain the hydrant is in the fully open position to
prevent seat damage from the heat. If you are installing using a threaded adapter, hand tighten until valve is snug, then
orient spout in the proper direction. Use a strap wrench if necessary. DO NOT OVERTIGHTEN.
5. Connect the water supply piping to the freezeless wall hydrant as desired. With a closed-end hose on the valve creating
back pressure, test the installation for leakage.
6. After the water supply connection is made, secure the hydrant to the structure using appropriate screws through the two
mounting holes on the casted back flange.
