Points of attention
- The surface beneath the rainwater column must be flat and sturdy. A full rainwater column is heavy.

- Use a leaf guard to prevent the rainwater column from filling up with debris.
- Ensure that the rainwater column is closed at the top to prevent it from becoming a breeding ground for insects.
