Why the watermark certificate is so important?

You’d be excused for not paying too much attention to a couple of labels on the packaging of a new showerhead or set of taps, but these two stickers are more important to your health, safety and wallet than you might realise. WaterMark and WELS are proof of a product’s quality and efficiency. Here’s what you need to know.

What is call watermark?

WaterMark™ is a certification trademark and used in relation to water supply, sewerage, plumbing and drainage goods. The plumbing industry in Australia supports the use of the WaterMark™ which, when used properly, is an excellent way of helping Australian consumers be confident about the quality of the plumbing product to which it is applied. The WaterMark™ is applicable to products manufactured both locally and overseas.

It is important that consumers are aware of the certification programme. If a product doesn’t carry a WaterMark certificate, plumbers cannot legally install it in this country. However, retailers may still sell non-certified products, so always check for a label.

What is call WELS?

WELS (Water Efficient Labelling Standard) is a scheme which requires manufacturers of plumbing products, sanitaryware and white goods to label their products with a star rating, which denotes their water efficiency in accordance with the regulatory standard AS/NZS 6400.

WELS is designed to encourage lower water consumption and help consumers make informed decisions when choosing water-using appliances. TheWater Rating website sums it up best: ‘the more stars on the WELS label, the less water that product will use, and the more money you will save.

Note: WELS and WaterMark are separate schemes – WELS relates to water usage, while WaterMark is proof that a product is high quality, suitable for Australian conditions and can be installed legally in your home.

Cost and environmental impact

The reduction of water usage could mean tangible changes in the next few years. A study found that by using water efficient products, Australians will help to:

  • Reduce domestic water consumption by more than 100,000 megalitres a year;

  • Save more than 800,000 megalitres (that’s more than in the Sydney Harbour!)

  • Savings will come from water-efficient showers (more than a third), washing machines (34%) and toilet and urinal usage (23%).

    All toilet, tapware, shower sold by The GMJ Company fully complies with the WaterMark Scheme. The products meet the requirements of the Australian Standards AS/NZS 3718:2005 – Water Supply – Tapware, and AS/NZS 3662:2005 – Performance of showers for bathing.
