TopTank 700L Rectangular Loft Water Tank, UV Stabilized LLDPE

TopTank 700L Rectangular Tank

The TopTank 700L Water Tank provides a reliable solution for gravity-fed plumbing systems and domestic reserve storage. This unit utilizes high-density polyethylene to ensure long-term durability in varied environmental conditions. Plumbers and site managers select this specific model for its low-profile dimensions and high volumetric efficiency within confined structural spaces.

Built for the Job

This storage vessel is engineered specifically for attic and loft installations where vertical clearance is limited. The rectangular footprint allows for better weight distribution across ceiling joists compared to vertical cylindrical tanks. It fits through standard internal access hatches, making it suitable for retrofit projects in existing residential buildings. The structural design prevents bulging when the container reaches full capacity.

• Gravity-fed domestic water systems requiring header tanks in roof voids.

• Secondary reserve storage for properties with intermittent municipal supply.

• Industrial rainwater harvesting setups with height restrictions.

Product Highlights

Food-Grade Material Construction

The manufacturer uses 100% virgin LLDPE to ensure the stored liquid remains free from chemical contaminants.

Advanced UV Protection

• Integrated carbon black additives prevent light penetration.
• The material resists algae growth and thermal degradation.

Technical Specifications

What’s Included

On-Site & Workshop Notes

• Always install this container on a flat, level, and fully supported base to prevent stress fractures.

• Use a marine-grade plywood spreader board if the joist spacing exceeds 400mm centers.

• Ensure all pipe connections use appropriate bulkhead fittings to maintain a watertight seal.

• Verify that the loft floor structure can support the 700kg static load of the full vessel.
