Tankworld Tasmania – 10 Year Poly Tank Warranty

Effective Date: 1st July 2025

At Tankworld Tasmania, we’ve been proudly supplying Tasmanians with quality poly water tanks for over 30 years. Our tanks are built tough for local conditions, manufactured to meet Australian Standards, and backed by decades of experience, stringent quality control, and a commitment to long-term customer satisfaction. That’s why we stand behind every tank with our Watertight Poly Tank Warranty.

1. Warranty Period

Round Poly Tanks:
10-year warranty from the date of delivery when installed in domestic applications.

Slimline Poly Tanks:
10-year warranty from the date of delivery when installed in domestic applications.

Other Products (including commercial applications and heavy-weight industrial tanks):
5-year warranty from the date of delivery, subject to appropriate use, installation, and environmental conditions.

Fittings (including inlet strainer, overflow, outlet, and ball valve):
1-year manufacturer’s warranty from the date of delivery.

2. Warranty Coverage

This warranty covers:

  • Defects in materials and workmanship under normal use.
  • Structural integrity of the tank body when correctly installed.
  • UV stabilization of the polyethylene material.

This tank has been manufactured for the storage of drinking water, and all materials are suitable for contact with drinking water.

3. Warranty Exclusions

This warranty does not apply to any defect, failure, or deterioration in the tank where any of the following is a contributing factor:

  • The tank is not properly secured upon delivery or is damaged through mishandling or being stored on its side for an extended period.
  • The tank is installed on an inadequate or improperly prepared base, including unboxed fill or uneven ground.
  • The site deteriorates due to erosion, subsidence, or lack of maintenance after installation.
  • The tank is relocated or moved from its original installation site.
  • The tank is modified or altered in any way without prior written approval from Tankworld Tasmania.
  • Fittings not supplied or installed by Tankworld Tasmania are attached to the tank.
  • Excessive water pressure, suction, or plumbing stress is applied to the tank or its outlets.
  • A sustained or temporary load is applied to the top of the tank, including standing, sitting, climbing, or placing objects on the roof.
  • The tank is used to store any substance other than potable (drinking) water at ambient temperature, including chemicals, greywater, or wastewater.
  • Damage is caused by natural disasters or environmental conditions including fire, flood, storm, earthquake, lightning, or high winds.
  • External damage occurs from tree roots, vermin, insects, machinery, tools, falling objects, or abrasive contact.
  • The tank is exposed to harmful fumes, chemical vapours, or foreign substances not compatible with polyethylene.
  • The tank’s surface shows cosmetic changes such as discolouration, fading, surface chalking, or algae growth. These are considered normal wear and do not affect performance.
  • Colour fade or surface deterioration resulting from prolonged exposure to sun, wind, frost, or ice is not covered.
  • The tank fails due to physical abuse, neglect, or malicious damage.
  • A defect or issue is not reported to Tankworld Tasmania within 7 days of being discovered, or the tank is not made available for inspection within 28 days of notification.

4. Conditions of Warranty

To maintain this warranty, the following conditions must be met:

Installation Requirements:

  • Tanks must be installed on a level, compacted crusher dust or road base surface.
  • Installation on fill is not recommended.
  • Retaining beams must be used to prevent erosion of the base material.
  • Tanks must be tied down during delivery and prior to installation.
  • Flexible hoses (minimum 30cm) must be used on all outlets.
  • Overflow plumbing must match inflow capacity and must be directed away from the tank base.

Tank Use:

Tanks are intended for the storage of potable (drinking) water at ambient temperatures only. Use for chemicals, greywater, or other non-potable contents will void this warranty.

Burial Depth Limitation:

Standard poly tanks must not be installed deeper than 400mm in-ground. Deeper installation is unsupported by the raw material manufacturer and will void this warranty.

Modifications or Misuse:

Any unauthorised modification, physical abuse, or applied load (e.g., plumbing strain) may distort the tank and void this warranty.
