Plumbing product certification
The WaterMark Certification Scheme is a mandatory certification scheme which ensures plumbing materials and products are fit for purpose and appropriately authorised for use in plumbing installations.
Under the Plumbing Code of Australia (Vol.3 of the National Construction Code), it is illegal for plumbing practitioners to install any of the plumbing and drainage products listed in Part A2 of the Code, if they do not have the appropriate authorisation or certification.
All authorised products must display the WaterMark symbol. If in doubt, you can find all certified materials and products on the WaterMark product database.
If the product cannot be found on the WaterMark database, you should contact the manufacturer and obtain confirmation that the specific product is authorised for use and has been WaterMark certified.
The Australian Building Codes Board is responsible for administering and managing the scheme.
