Saving Water

Aim to install water-efficient taps, toilets, washing machines and dishwashers to save you water and money throughout the year.

You can also adopt some water-saving habits that still keep you comfortable but can save you money and reserve Australia’s water supply.

If you have a rain water tank you can install a gauge which will help you to keep an eye on the water volume in your tank. The analogue way of checking water is to knock on the tank wall and listen to the change in sound!

Having trouble with your hot water heater? 

Check that your plumber/builder has installed a pressure reduction valve (PRV) either on your water meter (on the side that connects to the house) or before your hot water system. Some people choose to remove the pressure reduction valves from their meter to increase water pressure to the home. This is not only against the National Construction Code (Vol 3, B1P5 Pressure) but is very likely to damage your water appliances, especially during periods of low water use in the suburb which causes water pressure in the mains to increase. A pressure reduction valve ensures that all water flowing to the house or hot water service does not exceed 500 kPA, keeping your appliances and water fixtures safe.

To check if you have a PRV open your water meter box and look for a bell or cylinder-shaped device after the water meter. If there is no PRV, check your water supply to your hot water heater. If you cannot find a PRV you may like to call your builder or plumber to come and check for it and or install one. All standard building contracts should include a PRV as it is part of the National Construction Code in Australia.
