Plumbing product certification

There is a requirement in the Plumbing Code of Australia (PCA) for certain plumbing and drainage materials and products to be certified and authorised for use in a plumbing or drainage installation.  These materials and products are certified and authorised through the application of the WaterMark Certification Scheme.

WaterMarkTM Certification Scheme (WMCS)

Material and product failures in plumbing installations can cause failure of plumbing systems and lead to contamination of the water system. The WMCS is a mandatory certification scheme for plumbing and drainage products to ensure that plumbing and drainage materials and products are fit-for-purpose and appropriately authorised for use in plumbing installations. The Australian Building Codes Board (ABCB) manages and administers the WMCS.

In order to achieve WaterMark Certification, materials and products listed in the WaterMark Certification Scheme Schedule of Specifications must:

  • be tested by a recognised testing laboratory;
  • comply with an approved specification (either a relevant existing standard or an approved WaterMark Technical Specification);
  • be manufactured in accordance with an approved Quality Assurance Program; and
  • carry a warranty.

WaterMark product database

Materials and products complying fully with the applicable requirements of the WMCS are eligible to be certified by a WaterMark Conformity Assessment Body and are listed on the WaterMark Product Database.

The database may not contain the certified product you are looking for, as the details may not have been provided by the WaterMark Conformity Assessment Bodies to the ABCB for uploading.  However, a product or materials certification under the Scheme is identifiable by the presence of the WaterMark trademark on the item or its packaging.

Products outside the WMCS

The WMCS provides for the exemption from WaterMark certification.  Those that have formally been exempted can be found on the WaterMark List of Exempt Materials and Products.

The PCA includes a Tasmanian Appendix, which provides for local (State) authorisation and accreditation of certain plumbing products and systems.  These include septic tanks, on-site waste water management systems and unique plumbing products.  A unique plumbing product is a plumbing or drainage product that is:

  • a prototype
  • made on site
  • purpose built (the only one of its type)
  • imported from outside Australia for one-off use
  • determined by the Director of Building Control to be a unique plumbing product
