TopTank 1900L Cylindrical Tank
The TopTank Cylindrical Water Tank provides a reliable 1900-litre capacity for residential and commercial potable water storage. This vertical vessel uses food-grade polyethylene to ensure liquid safety and long-term durability. It suits rainwater harvesting systems and municipal backup setups in high-demand environments.
Built for the Job
Contractors specify these units for their structural integrity and ease of installation. The vertical orientation maximizes storage volume while maintaining a compact footprint on concrete plinths. Plumbers utilize these for gravity-fed systems or pressurized pump configurations. This storage solution handles the weight of nearly two metric tons of water without compromising the base structure. Site supervisors appreciate the lightweight empty weight which simplifies positioning before plumbing. The cylindrical design offers superior stress distribution compared to rectangular alternatives. This prevents corner fatigue and extends the service life of the installation.
-
Backup storage for domestic properties during municipal supply interruptions.
-
Collection point for large-scale rainwater harvesting from warehouse roofing.
-
Header tank for multi-story residential plumbing systems requiring gravity pressure.
Product Highlights

On-Site & Workshop Notes
-
Install this unit on a level, smooth concrete base at least 100mm thick.
-
Ensure all pipe connections use flexible couplings to prevent stress on the tank walls.
-
Check local building codes for required setbacks from property lines or structural foundations.
-
Do not bury this specific model underground as the walls are designed for above-ground atmospheric pressure.
-
Regularly inspect the inlet screen to prevent debris from entering the main chamber.
-
Use a standard hole saw for drilling additional inlet or overflow ports to ensure clean edges.
-
Always vent the tank correctly to prevent vacuum collapse during high-flow discharge.
