TopTank 1350 Litre Cylindrical Water Storage Tank

TopTank 1350L Cylindrical Tank

The TopTank 1350 Litre Tank provides a heavy-duty solution for potable water storage in residential, agricultural, and commercial environments. This rotationally molded vessel uses food-grade polyethylene to ensure safe water containment. It is engineered to withstand outdoor exposure in tropical climates while maintaining structural integrity.

Built for the Job

Site supervisors and plumbers specify this vertical storage unit for its balance of footprint and capacity. The cylindrical profile distributes internal hydrostatic pressure evenly across the walls, preventing bulging or stress fractures over time. It is commonly installed on ground-level concrete pads or elevated steel towers to provide gravity-fed water pressure to fixtures. The black finish serves a functional purpose by blocking light transmission, which effectively prevents algae growth inside the reservoir. This makes the unit suitable for long-term storage of borehole water or harvested rain.

• Residential backup water supply for multi-bathroom households or small apartment blocks.

• Agricultural irrigation buffering for greenhouses and small-scale livestock watering.

• Commercial facility water reserves for fire safety or sanitation during mains outages.

Product Highlights

Roto-Molded Construction

The manufacturing process creates a seamless, single-piece body that eliminates weak points found in welded alternatives.

Material Specifications

• UV-stabilized Linear Low-Density Polyethylene (LLDPE) prevents brittleness.
• Food-grade certified material ensures no chemical leaching into the water supply.

Technical Specifications

What’s Included

• 1 x 1350 Litre Cylindrical Storage Vessel

• 1 x Heavy-duty Threaded Manhole Cover

On-Site & Workshop Notes

• The installation surface must be a level, smooth, and reinforced concrete slab capable of supporting over 1.4 tonnes of static weight.

• Always use flexible connectors between the tank outlet and rigid PVC or PPR piping to prevent stress on the bulkhead fittings during expansion.

• Ensure the breather vent is clear of obstructions to prevent a vacuum from forming during high-draw periods, which could collapse the walls.

• Do not drag the unit across abrasive surfaces during positioning to avoid compromising the base thickness.
