TopTank 2500 Litre Cylindrical Water Tank, UV-Stabilized Polyethylene

TopTank 2500L Cylindrical Tank

The TopTank 2500 Litre Tank serves as a high-durability reservoir for potable water storage in residential, agricultural, and industrial environments. This vertical unit utilizes food-grade Linear Low-Density Polyethylene (LLDPE) to ensure chemical resistance and structural integrity. It meets the rigorous demands of site managers requiring consistent water supply for construction or facility backup.

Built for the Job

Plumbing contractors and site supervisors specify this vessel for its robust rotomoulded construction. The seamless design eliminates joints, which significantly reduces the risk of leaks under hydrostatic pressure. It functions effectively in harsh outdoor environments where high UV exposure typically degrades standard plastics. This container provides a reliable buffer for borehole systems or municipal supply failures.

• Rainwater harvesting setups for commercial buildings and large residential properties.

• Temporary water storage on construction sites for mixing mortar and general dust suppression.

• Secondary storage for multi-unit housing developments requiring gravity-fed distribution systems.

Product Highlights

UV-8 Stabilization

The outer layer features UV-stabilized pigments that prevent polymer breakdown and brittleness during long-term sun exposure.

Algae Prevention Design

• Multi-layer construction blocks sunlight penetration into the water column.
• The dark interior prevents the photosynthesis process required for microbial growth.
• Maintains water quality for longer periods compared to single-layer alternatives.

Technical Specifications

What’s Included

• 1 x 2500L Vertical Storage Tank

• 1 x Heavy-duty Threaded Manhole Cover

• Pre-moulded Inlet and Outlet Bosses

On-Site & Workshop Notes

• Always install the storage unit on a level, reinforced concrete plinth to prevent base deformation.

• Ensure all pipework connected to the 2500L container is independently supported to avoid stress on the tank wall.

• Verify that the ventilation cap is clear of obstructions to allow air displacement during rapid filling or drainage.

• Use flexible couplings when connecting rigid PVC or galvanized pipes to accommodate minor expansion and contraction.
