We've just moved into a new house which is a duplex in Sydney (Randwick area). The water pressure seems very low (in both units) versus our old house. We're seeing about 6L/minute from just about everywhere at the new place (the front garden taps, inside hot taps, laundry, upstairs cold and hot water taps). In our old house we were seeing about 24+Litres/minute (could fill a 12L bucket in 32 seconds) yet in the new place it's taking about 2 minutes to fill the same bucket... Like i say this is everywhere, including the garden taps in the new house which i presume have no water saving devices nor aeration filters etc attached. We do have instantaneous hot water systems fitted (24L/minute capacity i believe) however given we have such low flow at the front garden tap i would hazard a guess the hot water systems are not prime suspects, but i have no idea really.
I've asked the builder to do a pressure test (we're waiting..) but i thought i would ask if anyone knows about NSW/Sydney regulations relating to new dwellings (basix?) and perhaps being a duplex if that complicates matters (perhaps dividing the pipes, although both units have their own meter) or perhaps being a "multi-dwelling" that could complicate matters with basix water saving devices fitted to such dwellings.
Anyone exeperenced significantly low water pressure in their new (vs old) house? It's driving us nuts.
