Hi,
If you are not sure get a plumber out there asap he can check the flow rates, charge you a small fee and give you a certificate, it will save you a fortune.

Hi,
As per nsw law if you upgrade to the current water efficiency laws such as taps and shower heads and get a certificate from the plumber you do not pay for water usage the Tenant does, you only pat for the service fee.
