The National Construction Code requires any plumbing or drainage product of a type listed on the WaterMark Schedule of Products to be WaterMark certified before it can be installed.

Research undertaken by the ABCB revealed that Australian consumers of plumbing and drainage products often purchase from online stores, like eBay and Amazon, where non-WaterMark certified products are available.

Therefore, it is important to encourage your customers to look for the WaterMark, along with the licence number and product specification.
