The scope of the WaterMark Certification Scheme captures plumbing and drainage products where the installation is regulated by the PCA (excluding State and Territory Variations). Products installed outside the scope of the WaterMark Certification Scheme do not require WaterMark certification. These product categories currently include roof drainage systems, surface and subsurface storm water drainage systems, heating, ventilation and air-conditioning systems, on-site wastewater management systems and on-site liquid trade water systems. Also, some products have been predetermined to not require WaterMark certification and the WaterMark Schedule of Excluded Products lists those products.

Any products proposed to be used in a plumbing and drainage installation, that are not listed on the WaterMark Schedule of Products or the WaterMark Schedule of Excluded Products, require a risk assessment to be undertaken to determine if certification is required.

Refer to the How it works section for further information or contact a WaterMark Conformity Assessment Body.

NCP is an acronym for “non-compliant product”. A non-compliant product or material is not ‘fit for purpose’. It is used in situations that do not comply with the requirements of the NCC.
