Same Loading Units Different Flowrates

Hi

I have created a HWS system consisting largely of en-suits of bedrooms. Each en-suite has a two number of basins and 1 shower nozzle. They are calculated using the same method  (BS EN 6700), and have the same loading units.

They branch coming in differs, although this branch splits into a shower branch and basin branch.

Any assistance.
