Domestic Water Pressure

Did you know that the water pressure in you house, according to AS/NZS 3500:1, should be a
maximum of 500Kpa. In most areas you will find that the pressure coming into your house will be below
this. However in some areas like Byford, Treeby and suburbs at the bottom of the hills the inlet water

valve at the water meter.
