Why Choose WRAS Approved Products?

WRAS (Water Regulations Approval Scheme) is an ISO 17065 accredited certification body, meaning it operates to the highest international standards for product certification. To achieve WRAS approval, products undergo rigorous independent testing in accredited laboratories. This ensures they meet strict requirements for quality, safety and performance.

WRAS approved products are tested to confirm they:

  • Prevent contamination of drinking water
  • Avoid misuse, waste or excessive consumption
  • Deliver accurate water measurement
  • Are made from materials of suitable quality and durability
