All new homes need to meet plumbing standards, however default downpipe positions can sometimes be annoying. When reviewing your plans look for downpipes that are located on the front façade or close to outdoor living areas. You may find that standard downpipe positions are not necessarily the same as those shown on display homes.
Your new home plans will show the number and locations of all outdoor garden taps. Additional outdoor taps will provide better access for watering your garden and other cleaning applications. Some new housing estates will give you access to recycled water taps for garden irrigation; these taps will usually be purple, and the usage will be charged at a cheaper rate than non-recycled water.
If you plan on having a water tank connected to your toilets and washing machine, it will need to be plumbed into the home and also requires mains or recycled mains backup for continued supply if the tank becomes empty. You'll also need a water pump and an electrical connection for this pump to operate.
