RotoTank 100L Cylindrical Water Tank, UV-Stabilized Polyethylene

RotoTank 100L Cylindrical Tank

The RotoTank 100L Water Tank provides a compact and durable solution for liquid storage in residential, agricultural, and light commercial plumbing systems. Manufactured from high-quality, food-grade polyethylene, this vertical vessel ensures safe storage for potable water or compatible chemicals. Its cylindrical profile allows for efficient placement in areas with limited floor space or as a header tank in gravity-fed systems.

Built for the Job

Plumbers and site supervisors utilize this specific 100-litre reservoir for applications requiring a localized water supply or pressure buffering. The rotational molding process creates a seamless, one-piece body that eliminates the risk of joint failure under hydrostatic pressure. Due to its lightweight construction, contractors can easily transport and position this unit on elevated platforms or within narrow utility closets without specialized lifting equipment.

• Installation as a header tank for domestic gravity-fed hot water systems.

• Secondary storage for small-scale hydroponic or irrigation setups on-site.

• Buffer tank for water treatment systems or chemical dosing applications.

Product Highlights

Material Integrity

Constructed from UV-stabilized Linear Low-Density Polyethylene (LLDPE) to prevent structural degradation from direct sunlight exposure.

Sanitary Standards

• BPA-free material prevents leaching into stored drinking water supplies.
• Smooth internal walls inhibit the growth of algae and bacterial biofilm.

Technical Specifications

What’s Included

• 1 x 100 Litre Cylindrical Storage Tank

• 1 x Secure-fit Manhole Cover/Lid

On-Site & Workshop Notes

• Ensure the storage unit sits on a completely flat, level concrete plinth or a reinforced timber platform to avoid stress points.

• Use flexible connectors when piping to the inlet and outlet to accommodate minor expansion and contraction of the plastic walls.

• Verify local building codes regarding the support structures if installing this container at height for gravity-fed plumbing.

• Standard tank connectors can be fitted using a hole saw; avoid over-tightening fittings to prevent stripping the polyethylene material.

• Regularly inspect the lid seal to maintain water purity and prevent ingress of debris or insects into the reservoir.
