Manufacturing technology
  • Manufactured using latest rotational moulding technology
  • Rotational moulding technology is better than others for producing large, high quality products with low stresses and high durability
  • Only technology to have BIS approval for use in manufacturing water storage tanks having the ISI mark
  • Unibody construction without any welds or joints
  • Many manufacturers use blow moulding technology, which is more suitable for small products like water bottles
  • Blow moulding has inherent stresses due to high pressure. These stresses cause the product to fail when exposed to sunlight and adverse weather conditions
  • Many manufacturers use locally assembled machinery for rotational moulding, which hampers consistency and product quality
  • No fine print and no hidden conditions
  • Storewel guarantee is one you won’t need to use
  • Guarantee fine print often includes depreciation charts
  • Even free replacements involve the hassle of refitting the plumbing and movement of the tank
