Looking at splitting a feed and return line into 2 branches.
I have come up with 2 different manifold ideas but I am wondering what would be better to get equal pressure for each.
I have actually made option A but after making it I am not convinced that it will pass through the water equally (i.e the first pipe out will receive water first then once all through the second pipe out will get water)
As this is for central heating does it really matter? Would it mean one radiator gets hotter first?
