  6. Solar Water Heaters: Consider investing in a solar water heating system. In Australia, with its abundant sunshine, harnessing solar energy for water heating can be a sustainable and cost-effective option.
  7. Energy-Efficient Appliances: Choose energy-efficient dishwashers and washing machines, which consume less water and energy. Look for appliances with high ENERGY STAR ratings.

The Role of Government Initiatives

The Australian government is committed to promoting sustainability and eco-friendly practices, including in plumbing. The Water Efficiency Labelling and Standards (WELS) scheme is a prime example of such initiatives. The WELS scheme requires all water-using products to be registered and labeled with their water efficiency information, making it easier for consumers to make informed choices about the water-efficiency of plumbing products.

In addition to national initiatives, various states and territories have introduced rebates and incentives to encourage homeowners to adopt eco-friendly plumbing practices. These incentives often aim to offset the initial cost of purchasing and installing water-saving fixtures, rainwater harvesting systems, and solar water heaters.
