This Enduramaxx range covers large, above-ground vertical water-storage tanks from 500 to 30,000 litres. The options include standard non-potable tanks and dedicated CAT 5 Type AB break tanks, so the complete variant description must be checked before ordering.

Choose the correct tank type

• Non-potable: for compatible irrigation, rainwater, process-water and wash-down applications where drinking-water certification is not required.
• CAT 5 Type AB: incorporates an air-gap weir for a correctly designed installation requiring Fluid Category 5 backflow protection.

Each tank is rotationally moulded from medium-density polyethylene. The selected variant states its capacity, diameter, height, lid size and BSP male outlet. Several capacities have more than one footprint or height, so compare the full dimensions rather than capacity alone.

Confirm usable volume, water classification, inlet and overflow requirements, outlet size, supporting base, access and offloading before ordering. CAT 5 compliance depends on the complete installed arrangement, while a non-potable variant must not be assumed suitable for drinking water.
