 What do you look for in a bathroom? Stylish lines? Modern colours? Plenty of natural light? Oh, a good source of fresh air? What you should be looking for is the watermark. Why? Just because a product looks good doesn't mean it is good. And you'll find it on the tap, its fittings and the shower head. In fact, most plumbing and drainage products installed in Australia must be watermark certified. A licensed plumber simply can't fit it if it's not. Every certified product must come with a watermark logo and license number, included on the product when sold. Watermark is a mandatory scheme for plumbing and drainage products, and it means that products are being tested and certified to make sure that they work properly and the water you use is safe. So, how do you know if it's watermark certified? The product and its licensed details will be listed in the Watermark Product Database, located on the watermark website at watermark.abcb.gov.au. The database allows you to search for certificates and products by watermark license number, brand name, model name, model ID, licensee name or product description. Some problems are harder to see than others, so always make sure that it's safe and fit for purpose and always look for the watermark.
