    Hi Chesswood

    I believe Sydney Water has decided to reduce  Mains Pressure to protect their old degrading mains , and now mains pressure will only reach level 3 as is the case in our 8 level block at Caringbah aka Highfield

    We have dual pressure pumps that are serviced half yearly , only 1 issue over the last 3 years when a bit of a washer came in through the mains and stuck in one of the pressure pumps

    However the high pressure required to boost the water up 8 floors appears to be  damaging tempering valves and  residents on lower floor are encountering whistling and squealing plumbing noises.

    Plumbers also have differing opinions about how this issue is best handled as reducing pump pressure will compromise the water pressure to the upper levels

    Sorry I cannot be more helpful
