Setup Instructions
Follow these steps for proper installation of your KADAX Rain Tank:
- Choose Location: Select a stable, level surface near a downspout from your gutter system. Ensure the ground can support the weight of a full tank (approx. 210 kg).
- Prepare Gutter: Install the provided gutter connectors and filters into your existing downspout. Refer to the specific instructions included with the connectors for detailed steps.
- Connect Tank: Position the rain tank so that the inlet opening aligns with the gutter connector. Secure the connection to prevent leaks. The tank offers two options for drainage pipe attachment.
- Install Tap: Locate the designated tap opening on the tank. Screw the tap securely into place. Ensure it is tightened sufficiently to prevent water leakage.
- Optional: Install Stand (if applicable): If using a stand (sold separately or as part of a different variant), ensure it is assembled correctly and provides a stable base for the tank.

Operating Instructions
Using your KADAX Rain Tank is straightforward:
- Rainwater Collection: Once installed, rainwater will automatically flow from your gutter system, through the filter, and into the tank. The integrated filter helps prevent debris from entering the tank.
- Water Dispensing: To access the collected water, simply open the tap located at the bottom of the tank. You can connect a hose or fill a watering can directly.
- Overflow Protection: Ensure that the overflow mechanism (if present in your gutter connection kit) is correctly installed to prevent flooding once the tank is full.
- Planting Function: The wide top opening allows for planting flowers or herbs directly into the tank, adding a decorative touch while collecting water. Ensure proper drainage for plants if using this feature.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your rain tank:
- Filter Cleaning: Periodically check and clean the gutter filter to prevent blockages and ensure continuous water flow into the tank. Remove any leaves, twigs, or other debris.
- Tank Cleaning: Annually, or as needed, empty the tank and rinse the interior to remove any sediment buildup. Use a mild detergent if necessary, and rinse thoroughly.
- Winterization: Although the tank is frost-resistant, it is recommended to empty the tank completely before the first frost to prevent potential damage from freezing water expansion. Disconnect the gutter connection if possible.
- Tap Inspection: Check the tap periodically for leaks or blockages. Ensure it operates smoothly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No water collecting in tank. | Gutter filter blocked; improper gutter connection; no rainfall. | Clean gutter filter; check and secure gutter connection; wait for rain. |
| Slow water flow from tap. | Tap partially closed; sediment buildup near tap; tap faulty. | Ensure tap is fully open; clean tank interior and tap area; replace tap if necessary. |
| Water leaking from connections. | Loose connections; damaged seals. | Tighten all connections; inspect and replace any damaged seals or gaskets. |
| Tank overflowing prematurely. | Overflow mechanism blocked or not installed; tank full. | Check and clear overflow; ensure overflow pipe is correctly installed; tank is simply full. |
