Did you know most plumbing and drainage products need WaterMark certification?

The Plumbing Code of Australia (PCA) 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 by a licensed plumbing practitioner.

If a product listed on the Schedule of Products is to be installed in Australia, including those purchased via online stores like eBay and Amazon, the product must be:

  • WaterMark certified;
  • marked with the WaterMark trademark, WaterMark licence number and the applicable product specification;
  • listed on the WaterMark product database; and
  • provided with a Scope of Use statement specifying its intended use.
  • Any associated product packaging and promotional material must also be marked with the WaterMark trademark and licence number.


    It is legal to sell non-WaterMark certified plumbing and drainage products in Australia. However, if the product type is listed on the Schedule of Products, but is not WaterMark certified, a licensed plumbing practitioner is not permitted to install it.

    Also, if a non-WaterMark certified product is installed where a WaterMark certified product is required by the PCA, the state or territory plumbing administration may not accept the installation.

    For this reason it’s important that you look for the WaterMark on products and packaging before purchasing and installing, to ensure the product is certified and authorised for use. If you’re buying online, ask the supplier for this information if it’s not available on the website.

    If your client is supplying their own plumbing products for you to install, remember to ask them to look for the WaterMark and to only supply you with WaterMark certified products. Buying WaterMark certified products means they are fit for purpose, authorised for installation and safe for you and your clients.
