Approved plumbing products


The WaterMark Certification Scheme (WMCS) is a national mandatory certification scheme. It ensures plumbing materials and products are fit for purpose and appropriately authorised for use in plumbing and drainage installations.

Under the Plumbing Code of Australia (PCA), it is unlawful for plumbing practitioners to install any plumbing and drainage products listed in the PCA (and the technical standards) if the products do not have the appropriate authorisation or certification under the WMCS.

All authorised products must display the WaterMark symbol. If in doubt, you can find all certified materials and products in the WaterMark product database.

If you can’t find the product 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 WMCS scheme. For more information about the scheme, refer to the ABCB's website.
