Moving from Sydney to Adelaide?
If you're relocating from Sydney to Adelaide, expect visible limescale on taps and shower heads within weeks. You'll need to recalibrate your dishwasher's salt setting, increase kettle descaling frequency, and check your boiler warranty requirements. A shower filter and under-sink scale inhibitor are worth considering immediately.
