Product Support

PRIER has been manufacturing the C-155/157 Anti-Siphon Angle Sill Faucets since the late 1980's. 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 includes:

1. When the water is running, water leaks out from behind 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 shut off

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 angle sill faucets. This bibb washer is a standard 1/4 L beveled bibb washer, available from your plumbing supply house. The appropriate kit for this item is part # C-135KT-802.

5. The stem end is damaged and I cannot operate the 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.

The proper replacement stem for the C-135/137/235/155/255/165/265 is part # 231-0001.

6. How do I convert the faucet to loose key?

PRIER freezeless hydrants and angle sill faucets can be converted after installation from handle operated to a loose key operation. 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 product. To convert to the loose key vandalproof option, part number C-134KT-804 is required.

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.

The parts required for this is a C-434KT-906 Vacuum Breaker Replacement Kit

Installation Instructions:
To repair the vacuum breaker on any of the above items, it first needs to be removed from the valve. The vacuum breaker is sealed to the valve and needs to be heated with a torch to be removed. Once it is removed you can reinstall the new parts in the order as shown above.
