Operation
Once installed, the POOLHACKER fountain is ready to operate. Its dual-spray design and adjustable features allow for a customized pool experience.
Adjusting Spray Direction and Height
The fountain features 360° adjustable horizontal and vertical tubes, allowing you to customize the spray direction and height to suit your preference and pool layout. You can achieve various effects, from a wide waterfall to a focused spray.

This image demonstrates the versatility of the fountain, allowing users to adjust the spray to create various effects, such as cross water or parallel spraying, to suit different pool sizes and shapes.
Water pressure and spray height can be further adjusted using the side valve located at the bottom of the unit. Rotate the valve to control the flow of water and achieve your desired spray intensity.

This diagram shows the three settings for the side valve: Full Open (Low Pressure), Partial Open (Medium Pressure), and Full Close (High Pressure), allowing precise control over the fountain's output.
Cooling and Relaxation Benefits
The dual spray design actively cools down your pool water temperature by approximately 6-10 degrees Fahrenheit, providing a refreshing experience on hot days. Additionally, the gentle sound of falling water creates a soothing ambiance, contributing to a relaxing environment.

- Regular Inspection: Periodically inspect the fountain for any debris, leaves, or mineral buildup that might be blocking the nozzles or affecting water flow.
- Cleaning: If necessary, turn off the pump, remove the fountain, and clean it with mild soap and water. Rinse thoroughly to remove any soap residue.
- Winterization/Storage: During the off-season or when temperatures are expected to drop below freezing, remove the fountain from the pool. Drain all water from the unit and store it in a dry, protected area to prevent freezing and potential damage.
Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low or No Spray | Insufficient pump power | Ensure your pool pump is at least 0.2 HP. A 0.75 HP sand pump is recommended for optimal performance (spray height up to 14ft). |
| Low or No Spray | Clogged nozzles | Turn off the pump, remove the fountain, and clear any debris from the nozzles. |
| Low or No Spray | Side valve not fully open (for high pressure) | Adjust the side valve to the 'Full Close' position for maximum pressure. |
| Leaks at Connection | Loose connection or missing O-ring | Ensure the fountain is securely screwed onto the adapter and the adapter is tightly connected to the return jet. Check for and replace any damaged O-rings. |
| Fountain Submerged | Water level too high or insufficient extension | Adjust pool water level or install the optional 3-inch extension tube (if not already used). |
