Woodford Y34 Complete Head

Woodford 15003 Y34 complete Head. This head is for Y hydrants that have 1 1/4 inch Diameter Riser Pipe. When replacing a head, it is always a good idea to replace the plunger since the head is already off.

The Woodford Y34 complete head is a critical component used in outdoor water supply systems, particularly frost-free hydrants. Let’s explore its features and functionality:

1. Design and Components:

   • The Y34 complete head is specifically designed for Woodford Model Y34 frost-free wall hydrants.
   • It comprises several integrated parts that work together to ensure proper water flow and prevent freezing during cold weather.

2. Key Components:

   • Handle: The handle allows users to operate the hydrant. Turning the handle counterclockwise opens the water flow, while turning it clockwise shuts it off.
   • Packing Nut: The packing nut secures the hydrant stem and prevents water leakage.
   • Stem Assembly: The stem extends down into the hydrant body and connects to the water supply line.
   • Seat Washer: The seat washer provides a watertight seal when the hydrant is closed.
   • Drain Hole: Some models have a drain hole to prevent freezing by allowing water to escape.
   • Vacuum Breaker: A vacuum breaker prevents backflow contamination.
   • Locking Mechanism: Certain hydrant heads include a locking feature to prevent unauthorized use.
   • Material: The Y34 head is typically made of durable brass or other corrosion-resistant materials.

3. Functionality:

   • When the handle is turned counterclockwise, the hydrant opens, allowing water to flow.
   • Turning the handle clockwise shuts off the water supply.
   • The vacuum breaker prevents water from siphoning back into the water supply.
   • The drain hole ensures that any residual water drains out, preventing freezing.

4. Installation:

   • Proper installation ensures optimal functionality.
   • The Y34 head is attached to the hydrant stem, which extends through the hydrant body and connects to the water supply line.
