JasonD. I dont know what the regs are in pomyland but I believe your best bet would be to contact a Master Plumber in your area, it could be that your pipesizing is wrong.
In Queensland we must size the service to attain a pressure with all taps on and at the highest outlet 50kpa or 5m head (16ft)at a max flow velocity of 3m/sec.
