01

Identify the actual product and intended use

Define the plumbing or drainage product, its function, models and intended installation conditions. Compare that definition with the current WaterMark Schedule of Products and Schedule of Excluded Products. The schedule identifies relevant specifications; water contact or a familiar trade name alone does not establish the certification route. Confirm the current specification and relevant directions before treating a file as ready.

Conditional example: a filter assembly has a replaceable cartridge and a novel connection. Determine what the assembly and its components actually do and whether an approved specification covers them. A missing catalogue match is not evidence of exemption. If the product cannot be evaluated to an approved specification, clarify the specification-development or amendment route with the appropriate scheme participants.

02

Connect evidence to the configuration being supplied

Prepare a model and variant list, materials, drawings, intended-use limits, existing reports and manufacturing quality records. WaterMark evaluation connects testing, an applicable specification, approved production quality management and the declared scope of use. A laboratory report is an input to assessment, not a complete product licence. The competent WaterMark Conformity Assessment Body (WMCAB) determines the evidence it can accept.

Conditional example: a hose report describes different end fittings or an internal material from the proposed sale model. Identify the tested configuration and the differences. Ask the WMCAB whether the evidence represents that model and what further assessment is needed; do not transfer a report merely because the hose length, brand or appearance is similar.

03

Verify the licence and keep installation duties separate

A competent WMCAB evaluates and certifies the product; ABCB administers the scheme. Kayra can organise preparation but is not assumed to be a WMCAB, a testing laboratory or the licensing decision maker. Check the actual model, licence and status in the official product database and connect them to the product marking and Scope of Use statement.

Compare Scope of Use limits with the proposed installation, rather than treating a licensed component as approval for a whole building or plumbing design. Relevant installation and regulatory responsibilities remain. Check WELS separately where it applies to the actual product: WaterMark and water-efficiency registration are different obligations, and neither a shared brand nor a logo proves both are complete.

04

Responsibility

Kayra supports the actual plumbing-product scope, model/test/production records and coordination. An authorised WMCAB makes the WaterMark certification and licence decision; ABCB administers the scheme. The licence holder and manufacturer retain the product and production duties, while applicable installation and WELS work remain separate. Consultancy is not WMCAB designation and does not guarantee licensing or a date.
