Water-producing bathroom fittings in Australia need to comply with basic water-efficiency standards. As a part of the WELS scheme, they are rated and given a label that shows how efficient they are.

Pipe lagging

Lagging and heat loss

See how lagging (insulation) and the distance that hot water has to travel through your pipes can affect energy efficiency in your hot water system.

Grey water systems

Just because water from the tap has been used, it doesn't mean it can't be used again. See how grey water systems can help reduce your water waste.
