Installation & Pre-Purchase Checklist.
300 L Horizontal Water Tank – Dark Grey
- Check floor base: Ensure the unit is placed on a level surface capable of supporting full weight (~300 L of water ≈ 300 kg + tank weight).
- Space clearance: Allow for access around the tank for inlet, overflow, suction/outlet and occasional maintenance.
- Plumbing: Plan for rain-harvest inlet from downpipe, overflow outlet to drain or soak away, and outlet to pump or distribution system if needed.
- Exposure & finish: While UV-stabilized, ensure tank location is not subject to extreme heat or direct sunlight reflection from adjacent surfaces for prolonged periods.
- Use intent: Clarify whether it’s for non-potable use (watering) or whether needs potable certification if used for indoor or drinking water use; check local regulations accordingly.
- Installation accessories: Confirm lid size, access for cleaning, and whether first flush diverter or filter is needed for rainwater entry to reduce debris and leaves.
