TopTank 850L Loft Tank
The TopTank 850L Loft Tank provides a high-capacity water storage solution specifically engineered for residential and commercial attic spaces. This rectangular unit utilizes food-grade polyethylene to ensure safe potable water containment. Its low-profile design allows for installation in areas with restricted vertical clearance where standard cylindrical tanks cannot fit.
Built for the Job
Contractors prioritize this storage solution for gravity-fed plumbing systems in multi-story buildings. The rectangular footprint distributes weight more effectively across ceiling joists compared to tall vertical tanks. It is frequently used for header tank applications or as primary storage in houses with pitched roofs. Plumbers find the flat sidewalls easier for drilling precise inlet and outlet holes using standard hole saws. The material resists corrosion from treated municipal water, ensuring a long service life without the risk of rust or scale buildup common in older metal cisterns.

On-Site & Workshop Notes
-
Always install the unit on a flat, level, and fully supported base that exceeds the tank footprint dimensions.
-
Use flexible pipe connectors at the inlet and outlet to accommodate slight expansion and contraction of the plastic walls.
-
Verify loft hatch dimensions before delivery to ensure the rectangular profile can pass through the access point.
-
Tighten the lid securely after installation to prevent debris or insects from entering the potable water supply.
