Setup and Installation
This section provides general guidance for setting up your FloodStop Controller Unit. For detailed, kit-specific instructions, please refer to the manual included with your complete FloodStop leak detection kit.
Components Overview
- Controller Unit: The central processing unit for leak detection and valve control.
- Motorized Ball Valve: Connects to your water supply line to automatically shut off water flow.
- Water Sensor: Detects the presence of water and sends a signal to the controller.
- Power Adapter: Provides primary power to the controller (AC/DC, not included with this unit).
- AA Batteries: Optional backup power source (4 AA batteries, not included).
Installation Steps (General)
- Mount the Controller: Securely mount the controller unit to a wall near the appliance or fixture you wish to protect. Ensure it is in a location where you can easily access the buttons and view the status indicators.
- Connect the Valve: Install the motorized ball valve into the main water supply line of the appliance. Ensure proper plumbing connections to prevent leaks.
- Connect the Sensor: Place the water sensor on the floor or in a drip pan in the area where a leak is most likely to occur. Connect the sensor cable to the designated port on the controller unit.
- Connect Power: Plug the AC/DC power adapter (if using) into the controller unit and then into a standard electrical outlet. For backup power, insert 4 AA batteries into the battery compartment.
- Test the System: After installation, perform a system test to ensure proper functionality. This typically involves placing a small amount of water on the sensor to trigger a leak detection and verify the valve closes.

Operating Instructions
The FloodStop Controller Unit is designed for simple operation. The front panel features three illuminated buttons: OPEN, CLOSE, and MUTE.
- OPEN Button: Press this button to manually open the connected valve, allowing water flow. The corresponding indicator light will illuminate.
- CLOSE Button: Press this button to manually close the connected valve, stopping water flow. The corresponding indicator light will illuminate. This feature is useful for temporarily shutting off water, such as when leaving for vacation or during appliance maintenance.
- MUTE Button: If a leak is detected and the alarm sounds, press the MUTE button to silence the audible alarm. The valve will remain closed until manually opened or the leak condition is resolved.
- Status Indicators: The illuminated lights above the buttons provide visual feedback on the valve's status (open/closed) and system alerts.
- Adjustable Sensor Sensitivity: The controller unit features adjustable sensor sensitivity, allowing you to fine-tune how readily the sensor detects water. Refer to your kit's specific manual for details on adjusting this setting.
- Monthly Auto-Cycling: The system performs a monthly automatic cycle of the valve(s) to ensure they remain operational and prevent mineral buildup. This is a maintenance-free feature.

Maintenance
- Monthly Auto-Cycling: The FloodStop system is designed for minimal maintenance, featuring an automatic monthly valve cycling to ensure proper function and prevent seizing.
- Battery Replacement: If using the optional battery backup, regularly check the battery status. Replace the 4 AA batteries as needed to ensure continuous backup power during outages.
- Sensor Cleaning: Periodically inspect the water sensor for any debris or buildup that might interfere with its ability to detect water. Clean gently with a soft, damp cloth if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not responding / No power | Power adapter unplugged or faulty; dead backup batteries. | Check power adapter connection and outlet. Replace AA batteries if installed. |
| Valve not closing during leak detection test | Sensor not detecting water; valve connection issue; faulty valve. | Ensure sensor is wet and connected. Check valve wiring. Manually test valve with CLOSE button. |
| False alarm / Valve closes without a leak | Sensor sensitivity too high; sensor placed in a damp area; sensor malfunction. | Adjust sensor sensitivity (refer to kit manual). Relocate sensor to a dry area. Inspect sensor for damage. |
| Audible alarm sounds continuously | Leak detected; MUTE button not pressed. | Locate and address the leak. Press the MUTE button to silence the alarm. |
