Can anyone please advise me on how I can get my hands on a typical, generic plumbing schematic for the average Australian home? I have been told that the pressure on the hot water supply line and the cold water supply line, in the average Aussie home, is different. As all plumbing systems, with which I am familiar, are closed loop, the pressure is balanced on both the cold and hot side. I can’t understand how this is possible unless there are two separate water supply lines for each house. Can you steer me in the right direction in order to figure this out.
Pressure limiting valve on the hot water system, BUT not all hot water systems.
All advice is given with-out seeing the job, and hence all advice MUST be taken as advice with limited knowledge on the exact situation. NO responsibility can or will be taken. And yes, I am a licensed plumber with my own business in Brisbane Australia
