Additional Info
Prier has manufactured the C-155/157 Anti-Siphon Angle Sill Faucets from the late 1980's until today. This product has all the time tested features of our C-135 series, with the added protection of a vacuum breaker and backflow preventor. It is a simple operating product that is fairly simple to repair.
Possible Repair Issues for the C-155 Angle Sill Faucet:
1. When the water is running there is water leaking from under the handle
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.

2. The Angle Sill Faucet drips after shutoff
The Angle Sill Faucet/Hose Bibb may drip for a few moments after shutoff. If the water continues to drip after that time, you most likely need to replace the bibb washer.
Prier utilizes a 1/4 L Beveled Bibb Washer for our Angle Sill Faucets. The appropriate Part Number for that item is C-135KT-802.

5. The stem end is damaged and you cannot operate the Angle Sill Faucet
Occasionally the stem of the Prier Angle Sill Faucet gets damaged beyond repair. This is most commonly caused by the hydrant being operated by pliers and damaging the brass on the end.
To determine the proper replacement stem, you need to determine the following:
1. Length of the stem, from brass tip to brass tip. Do not include the rubber bibb washer in this measurement.

2 1/2" Prier Part Number 231-0002
6. How do I convert the Angle Sill Faucet to Loose Key Vandalproof Design?
Prier Freezeless Hydrants and Angle Sill Faucets can be converted after installation from handle operated to Loose Key Vandalproof Design. This design allows for operation only with the provided operating key. It prevents operation of the Freezeless Hydrant or Angle Sill Faucet by vice grips or needle nose pliers.
Commonly this change occurs to prevent unauthorized usage of the Freezeless Hydrant or Angle Sill Faucet. To convert to Loose Key Vandalproof Operation, order the Prier Loose Key Conversion Kit, Part Number C-134KT-804.

8. Water is leaking from the holes on the vacuum breaker
The rubber washer inside the vacuum breaker has failed and needs to be replaced. This is accomplished by unthreading the vacuum breaker from the body of the hydrant and replacing the internals. The vacuum breaker is sealed to the body with a body sealant and may require heat to break loose.
