Re: Larger plumbing pipes in WA 7Feb 03, 2018 1:39 pm You could spend your $1500 and find that you have no pressure issue. The water regulator specifies a very large window of 'allowable' pressures supplied to customers. There would be a significant difference in flow rates for people living in the lower pressure areas compared to higher pressure. Even comparisons between the same suburb wouldn't mean it was an individual house problem, because the way that the water supply works sometimes means even neighbouring houses will get water from a different source (and potentially different pressure). Very generally speaking, if your house is on a hill, then your pressure probably won't be as good as if you live in a valley / close to sea level. There are so many variables that I would say your $1500 is probably not worth it. Also agree that there's often fittings in taps etc to reduce the flow rates. Ours popped out of the bath tap by accident and it fills so much faster now! Re: Larger plumbing pipes in WA 8Feb 03, 2018 2:18 pm The maximum pressure within the home is mandated to not exceed 500 kPa. The hydraulic performance at the end fixtures is determined by hydraulic calculations that takes into account the maximum and minimum mains water supply pressures and the pipe sizing calculations 'shall' (note that AS/NZS 3500.1.3.2.3.2 states "shall" and not must) use the minimum pressure. Unfortunately, calculations for individual properties are often not done and home owners often end up with cookie cutter plumbing. 3in1 Supadiverta.
