What Does the Warranty Cover?

The Clark Tanks manufacturer’s warranty covers defects or faults attributable to defective materials or workmanship, subject to the manufacturer’s conditions.

Where a qualifying defect is established, Clark Tanks may, at its discretion, repair the product or provide a replacement of comparable specification.

Important: Where a replacement is supplied, the manufacturer’s contribution is calculated on a pro-rata basis according to the original purchase price and the remaining warranty period. The warranty does not necessarily provide a full-value replacement throughout its duration.

Important Warranty Conditions

To maintain eligibility under the manufacturer’s warranty, customers must comply with the applicable conditions, including:

• Proof of purchase: Retain your tax invoice or receipt as evidence of purchase.
• Correct installation: Tanks must be installed on a suitable base in accordance with Clark Tanks’ written installation instructions.
• Appropriate use: Standard SG ≤ 1.0 water tanks are designed for potable water storage at temperatures not exceeding 40°C. Higher-SG tanks must only be used for compatible substances approved by the manufacturer.
• Proper maintenance: Tank bases, fittings, pipework, inlets and overflows must be maintained in accordance with the manufacturer’s requirements.
• Original purchaser: The manufacturer’s warranty applies to the original purchaser and is not transferable.
• Modifications and relocation: Relocation, modifications or repairs require prior written approval from Clark Tanks where specified by the warranty.

For detailed base preparation and plumbing requirements, refer to our Clark Tanks information section and the manufacturer’s Delivery & Installation Guide.

What Is Not Covered?

The manufacturer’s warranty contains exclusions for defects or damage arising from circumstances including:

• Incorrect site preparation, inadequate tank base support or improper installation.
• Failure to follow the manufacturer’s installation, usage or maintenance instructions.
• Use of incompatible liquids or exceeding the tank’s specified SG or temperature rating.
• Unauthorised modifications, repairs or relocation.
• Damage caused by storms, flooding, fire, hail, wind, tree roots or other specified external events.
• Damage caused by excessive loads on the tank roof or insufficient overflow capacity.
• Improper handling, storage or transportation after delivery.
• Normal wear and tear, weathering, colour changes or fading.
• Normal distortion or bulging of polyethylene tank walls, particularly during high temperatures.

These are examples only. Please consult the full Certificate of Warranty for all exclusions and limitations.

Making a Warranty Claim

If you believe your Clark Tanks product has developed a manufacturing defect, please notify Tank Shop or Clark Tanks promptly.

Under the manufacturer’s warranty claim procedure:

1. Notify the manufacturer within 7 days of the fault or defect occurring. The manufacturer must be given an opportunity to inspect the product within 28 days.
2. Complete the manufacturer’s warranty claim form, available through the Clark Tanks website.
3. Provide supporting information, including proof of purchase, photographs and details of the suspected defect where requested.
4. Allow assessment by Clark Tanks to determine whether the claim is covered under the manufacturer’s warranty.

Reasonable direct costs of making a warranty claim may initially be payable by the purchaser. The manufacturer provides for reimbursement where the defect is covered by its warranty or the Australian Consumer Law.

Your Rights Under Australian Consumer Law

The Clark Tanks manufacturer’s warranty is provided in addition to any rights and remedies available under the Australian Consumer Law (ACL).

Australian Consumer Law provides consumer guarantees that cannot be excluded. Depending on the circumstances, customers may be entitled to a repair, replacement, refund or compensation for reasonably foreseeable loss or damage.

The manufacturer’s warranty periods, exclusions and claim procedures do not remove any applicable statutory consumer rights.
