Certified plumbing products - WaterMark

Material and product failures in plumbing installations can cause failure of plumbing systems and lead to contamination of the water system. The WaterMarkᵀᴹ Certification Scheme (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.
