Cold water diverters
In most plumbing setups, it takes a while for hot water to reach the hot tap when it's turned on. Cold water diverters recycle the cold water which would otherwise pour down the drain in this time.
WELS labels and ratings
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.
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.
Water meters
Find out what the law says about the installation and operation of water meters, how they work, and what you can and can't do with them.
Sub metering and smart water meters
See what the law says about water sub metering for apartment blocks, and using smart meters to assess and manage your water usage.
