TopTank 920L Rectangular Tank
The TopTank 920L Loft Tank serves as a high-capacity header or storage unit designed specifically for installation in attics, crawl spaces, and areas where vertical clearance is limited. This food-grade polyethylene vessel provides reliable water containment for gravity-fed plumbing systems. The rectangular footprint ensures efficient space utilization on structural platforms.
Built for the Job
Site supervisors and plumbers specify this rectangular storage solution for residential and commercial retrofits where a standard cylindrical tank cannot fit through access hatches or under low roof pitches. The low-profile design distributes the weight of 920 litres of water over a wider surface area compared to vertical models. This helps manage structural load requirements when positioned on reinforced joists. The seamless rotational molding process eliminates joints, preventing leaks under constant hydrostatic pressure. This container remains a standard choice for header tanks in multi-story gravity systems across Kenya.
-
Installation in roof voids for gravity-fed bathroom and kitchen supplies.
-
Secondary water storage for facility managers in height-restricted utility rooms.
-
Header tank applications for solar water heating systems requiring consistent pressure.
Product Highlights
- LLDPE Construction
-
The unit utilizes high-quality Linear Low-Density Polyethylene which resists impact and chemical degradation over long service lives.
- Environmental Resistance
-
- UV-stabilized material prevents brittleness when exposed to indirect sunlight in open lofts.
- Food-grade composition ensures the stored liquid remains safe for domestic use without plastic leaching.
- Algae-resistant properties maintain water quality by blocking light penetration through the tank walls.

On-Site & Workshop Notes
-
Ensure the supporting platform is perfectly level and constructed from a solid material like 18mm marine plywood to support the full 920kg load.
-
Verify that the loft hatch dimensions allow for the width and height of the empty vessel before attempting interior installation.
-
Use standard tank connectors for inlet and outlet drilling; do not over-tighten fittings to avoid stressing the polyethylene walls.
-
Position the unit away from heat sources or sharp structural debris that could puncture the base during seasonal house movement.
