C-234 | PRIER's Original Design

PRIER C-234 provides a year round source of water to areas of structures that are subject to freezing temperatures. The hydrant valve is connected to the supply piping in the heated portion of the structure, eliminating the possibility of freezing.

Ordering the C-234 gives you the same style hydrant as the C-134 but with a vandalproof extended lockshield with operating key.

The PRIER C-234 is the original freezeless hydrant that is made in the same heavy pattern fashion that made it famous. It is available in stock lengths from 1 1/2" to 24", and longer sizes are available on request.

Additional Info

PRIER has manufactured the C-134/234 Freezeless Wall Hydrant since 1949. This freezeless hydrant has truly passed the test of time. It is a simple operating product that is fairly simple to repair.

Possible Repair Issues for the C-234 Freezeless Wall Hydrant:

1. When the water is running, water leaks out from behind the handle [VIDEO]

This is a common maintenance occurrence for any packed valve of any brand or manufacture. It is overcome by simply tightening the packing nut with a crescent wrench. This will force the packing tighter around the stem to eliminate leakage.

Occasionally, the packing will need to be replaced if the packing nut has been repeatedly tightened.

The packing kit required for this reapir is part number C-134KT-803.

2. The hydrant drips after shutoff [VIDEO]

A freezeless wall hydrant shuts off inside the heated portion of the structure therefore, the water inside the hydrant will drain out after shutoff. The shutoff point could be any distance from 4" to 24" inside the structure. This installation should also be pitched to allow the water to easily drain out of the hydrant. The hydrant may drip for up to 60 seconds after shutoff. If the water continues to drip after that time, you most likely need to replace the bibb washer.

To determine which bibb washer your hydrant requires, you need to determine the type of stem in the hydrant. That can be accomplished in a few different manners.

   1.   Determine the date of installation:

  1. Before 1972, PRIER utilized a 1/4 L beveled bibb washer for freezeless hydrants. The appropriate kit for this item is part number C-135KT-802.


  1. After 1972 PRIER used a OO beveled bibb washer for this style freezeless hydrant. The appropriate kit for this item is part number C-134KT-802.




  2.   Determine the type of stem inside the freezeless hydrant

In order to distinguish the proper replacement bibb washer, you will need to determine the following:

  1. The length of the stem, from brass tip to brass tip. Do not include the rubber bibb washer in this measurement.
  2. The "A" Dimension as shown on the picture below. This "A" Dimension will either be 1/2" or 9/16". A caliper may be necessary to determine this dimension.
  3. Using the acquired dimensions, determine which bibb washer is required from the chart below:

3. Water is leaking from the hydrant inside my house

Unfortunately, your freezeless hydrant is broken, most likely beyond repair. This happens when the water becomes trapped within the hydrant. The water freezes, expands and ruptures the copper shaft of the hydrant located on the inside the structure. The most common reason for this problem is leaving the garden hose attached during freezing weather, or the hydrant was not installed with the proper drainage pitch.


Please remove the handle to prevent accidental operation until the problem is repaired by your plumber.


4. The operating key is missing from my hydrant

For any one of numerous reasons, your operating key may be missing. PRIER's operating key is unique to its products - it has one flat side and the rest is rounded. This style key mates perfectly with our stem-end for a snug fit and years of reliable operation.

The required part number is C-108KT-808.

5. How do I convert my hydrant to handle design?

PRIER freezeless hydrants and angle sill faucets can be converted after installation from loose key operated to handle operation. 

To convert to the handle option, part number C-234KT-804 is required.

6. The stem end is damaged and I cannot operate the freezeless hydrant

Occasionally the stem of the PRIER hydrant gets damaged beyond repair. This is most commonly caused by the hydrant being operated by pliers and damage to the brass on the end.

To determine the proper replacement stem, you need to determine the following:

1. Overall length (OAL) of the stem, from tip to brass tip. Do not include the rubber bibb washer in this measurement.

2. The "A" Dimension as shown on the picture below. This "A" Dimension will either be 1/2" or 9/16". A caliper may be necessary to determine this dimension.
