3. Product Overview
The Prier P-164D04 is a heavy-duty, quarter-turn frost-free anti-siphon outdoor hydrant. It is constructed from brass, copper tubing, stainless steel, and aluminum components, designed for durability and reliable performance in various weather conditions. Its frost-free design allows the valve seat to be located inside the heated portion of the structure, preventing freezing.
Figure 1: Prier P-164D04 Hydrant showing overall dimensions. The hydrant measures approximately 10 inches (24 cm) in total length, with the main body and handle visible, and a copper pipe extending downwards.
Key Features:
- Quarter-Turn Operation: Provides quick and easy control of water flow.
- Frost-Free Design: The valve closes inside the heated wall, preventing water from freezing in the pipe exposed to cold.
- Anti-Siphon (Vacuum Breaker): Prevents contaminated water from being siphoned back into the potable water supply.
- Durable Construction: Made with heavy brass, copper tubing, stainless steel, and aluminum for long-lasting performance.
- Inlet/Outlet: 1/2" MIP x 1/2" SWT connections.
- Length: 4-inch length, designed to connect within the heated portion of a structure.
4. Setup & Installation
Proper installation is crucial for the frost-free and anti-siphon features to function correctly. If you are unsure about any step, consult a professional plumber.
Tools and Materials Required:
- Pipe wrench or adjustable wrench
- Pipe cutter (if modifying existing plumbing)
- Soldering equipment (torch, solder, flux, steel brush) if using sweat connections
- Thread sealant tape or pipe dope (for threaded connections)
- Drill and appropriate bits (for mounting)
- Mounting screws/anchors
Installation Steps:
- Prepare the Location: Select an exterior wall location where the hydrant's inlet can connect to a water supply line within the heated portion of your structure. The 4-inch length of this hydrant is designed for standard wall depths.
- Shut Off Water Supply: Locate your main water shut-off valve and turn off the water supply to your home. Open a nearby faucet to drain the lines and relieve pressure.
- Create Wall Opening: If installing in a new location, carefully create an opening in the exterior wall for the hydrant body and a corresponding opening in the interior wall to access the water supply line.
- Connect to Water Supply:
- The hydrant features 1/2" MIP (Male Iron Pipe) x 1/2" SWT (Sweat) connections.
- For threaded connections, apply thread sealant tape or pipe dope to the male threads of the water supply line. Carefully thread the hydrant onto the supply line, ensuring a tight, leak-free connection.
- For sweat connections, ensure surfaces are clean. Apply flux to both the hydrant's sweat connection and the copper supply pipe. Solder the connection according to standard plumbing practices. Note: If soldering, disassemble the hydrant first to protect internal rubber seals from heat damage.
- Position and Secure: Ensure the hydrant is properly angled for drainage when shut off. Mount the hydrant securely to the exterior wall using appropriate screws and anchors.
- Restore Water Supply: Slowly turn the main water supply back on. Check all connections for leaks.
- Test Operation: Turn the hydrant handle to the open position and check for water flow. Turn it off and ensure the flow stops completely.
5. Operating Instructions
The Prier P-164D04 hydrant features a simple quarter-turn operation for water control.
- To Open: Turn the handle approximately 90 degrees (a quarter-turn) counter-clockwise to open the valve and allow water to flow.
- To Close: Turn the handle approximately 90 degrees (a quarter-turn) clockwise to close the valve and stop water flow. Ensure the handle is fully turned to the closed position to engage the frost-free feature and prevent drips.
- Anti-Siphon Feature: The integrated anti-siphon (vacuum breaker) mechanism prevents backflow of non-potable water into your drinking water supply. This device operates automatically.
6. Maintenance
Regular maintenance ensures the longevity and proper function of your Prier hydrant.
- Winterization: Before the first freeze of the season, it is critical to disconnect all hoses, splitters, and other attachments from the hydrant. This allows any residual water in the hydrant's spout to drain completely, activating the frost-free mechanism and preventing freezing damage.
- Cleaning: Clean the exterior of the hydrant with a soft cloth and mild soap and water. Avoid abrasive cleaners or pads that could damage the finish.
- Leak Checks: Periodically inspect the hydrant for any signs of leaks, especially at connection points. Address any leaks promptly to prevent water damage.
- Vacuum Breaker Inspection: The anti-siphon device (vacuum breaker) is designed to prevent backflow. If you notice constant dripping from the vacuum breaker cap or water not flowing correctly, it may require inspection or replacement.
