1. Product Overview
The Red Flag Products Auto Fill Valve is designed to automatically maintain a desired water level in various applications such as ponds, water tanks, and skimmers. Constructed from durable ABS plastic and stainless steel, it resists corrosion and water damage, ensuring reliable performance over time.
Key Features:
- Adjustable arm for vertical or horizontal installation.
- Durable ABS and stainless steel construction.
- Standard 1/2-inch pipe thread inlet.
- Includes nut and gasket for "through-wall" mounting.
- Free flow outlet.
2. Safety Information
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in property damage or injury.
- Ensure all connections are secure and watertight to prevent leaks.
- Do not exceed the maximum operating pressure of 40 PSI.
- If connecting to a municipal water supply for aquatic environments, be aware that tap water may contain chlorine or other chemicals harmful to aquatic life. Consider using appropriate water treatment additives if substantial amounts of water will be added.
- Keep the valve and its components out of reach of children.

4. Setup and Installation
Follow these steps to install your Auto Fill Valve:
- Prepare Mounting Location: Identify a suitable location in your pond, tank, or skimmer where the water level needs to be maintained. This location should allow the float arm to move freely without obstruction.
- "Through-Wall" Installation: If mounting through a wall or bulkhead, drill an appropriately sized hole. Insert the threaded inlet of the valve through the hole. Place the gasket on the threaded portion on the outside of the wall, then secure it with the mounting nut. Tighten firmly by hand, then use a wrench for a final snug turn, ensuring not to overtighten.
- Connect Water Source: Attach a standard 1/2-inch pipe thread water supply line to the inlet of the valve. Use appropriate thread sealant (e.g., PTFE tape) to ensure a watertight connection.
- Adjust Float Arm: The float arm can be adjusted to set the desired water level. The arm can be positioned vertically or horizontally. Loosen the wing nut on the arm, adjust the float to the desired height, and then re-tighten the wing nut. The valve will close when the water level reaches the float.
- Test System: Slowly turn on the water supply. Check for any leaks at the connections. Observe the valve filling the system and ensure it shuts off correctly when the desired water level is reached. Make further adjustments to the float arm if necessary.

5. Operation
Once installed and adjusted, the Red Flag Products Auto Fill Valve operates automatically. As water evaporates or is lost from the system, the water level drops, causing the float to lower. This opens the valve, allowing water to flow in until the float rises to the pre-set level, at which point the valve closes. This process ensures a consistent water level without manual intervention.
6. Maintenance
Regular maintenance helps ensure the longevity and proper function of your auto fill valve:
- Periodic Inspection: Annually inspect the valve for any signs of wear, damage, or debris accumulation.
- Clean Float and Arm: Ensure the float and arm are free from algae, mineral deposits, or other obstructions that could impede their movement. Clean with a soft brush and water if necessary.
- Check for Leaks: Periodically check all connections for leaks. Tighten connections if any drips are observed.
- Winterization (if applicable): In freezing climates, if the system is exposed to freezing temperatures, disconnect the water supply and drain the valve to prevent damage from ice expansion.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not fill. | Water supply off; float arm stuck; debris in valve. | Ensure water supply is on; check float arm for obstructions; inspect valve for debris and clean. |
| Valve overfills. | Float arm set too high; float arm stuck; valve mechanism faulty. | Adjust float arm to a lower position; check float arm for obstructions; if problem persists, valve may need replacement. |
| Water leaks from connections. | Loose connections; insufficient thread sealant; damaged gasket. | Tighten connections; reapply thread sealant; inspect and replace gasket if damaged. |
