4. Filling the Base
Properly filling the base is crucial for stability and safety. The base is designed to hold approximately 330 lbs when filled with a mixture of sand and water.
- Locate Fill Ports: Identify the fill ports on each of the two base plates. These are typically covered with twist caps.
- Recommended Filling: For optimal weight and stability, it is recommended to fill the base with 90% sand and 10% water.
- Filling Procedure: Carefully pour sand into the fill ports until each section is approximately 90% full. Then, add water to fill the remaining 10% of the capacity. Ensure a tight seal by securely fastening the twist caps.
- Preventing Mold: To prevent mold or algae growth inside the water-filled sections, consider adding a small amount of white vinegar or bleach to the water.
