See below notice from the ABCB.
The COVID-19 (coronavirus) pandemic has seen an increase in the purchase by those performing do it yourself tasks, of plumbing products such as toilet seat bidet douches, handheld bidet sprays and trigger sprays, and other bidet type products that are connected to toilet water supplies.
The Australian Competition & Consumer Commission (ACCC) has just published an alert, COVID-19: Supplying and installing bidet products on the Product Safety Australia website: https://www.productsafety.gov.au/news/covid-19-supplying-and-installing-bidet-products.
The ACCC has prepared the alert for suppliers and consumers in consultation with the ABCB.
The key message of the communique is that the installation of bidet products connected to the drinking water supply must be undertaken by a licensed plumber and hold WaterMark certification. The alert will also be posted on the ABCB website.
If you have any questions, please direct them to me.
Kind regards
