The Relationship Between Watermark, WELS, And Australian Standards

Navigating bathroom product certifications can be confusing, but understanding how Watermark, WELS, and AUSTRALIA STANDARD work together simplifies the process. Think of these as three complementary layers of protection. First, AUSTRALIA STANDARD specifications (like AS/NZS 3718 for TAPWARE, AS/NZS 1172 for TOILETS, and AS/NZS 3662 for SHOWER systems) establish the technical requirements products must meet . Second, Watermark certification verifies that products have been independently tested and comply with these standards, ensuring they are safe and fit for purpose . Finally, the WELS scheme rates products based on water efficiency, helping consumers make informed choices about running costs and environmental impact . For example, a WELS-registered tap will display its star rating and flow rate, while its Watermark certification guarantees it meets AS/NZS 3718 requirements . All three elements are mandatory for regulated products installed in Australian plumbing systems . By choosing fixtures that carry both Watermark certification and WELS registration, consumers ensure complete compliance with Australian regulations while enjoying products that perform reliably and conserve water.
