Given that you have the correct spacing between the lines, and from
the walls of the tun, your manifold will work better if you reduce the
distance runoff must travel to get to the outlet i.e., if the outlet
came off the centre of line 5 in your diagram (between line 2 and line
3), and all the pipes were slotted with the exception of the outlet
pipe. That way runoff will have a more direct route to the outlet
pipe.
In other words, the majority of the collection pipes in your manifold
should run in the same direction as the outlet pipe.
Looking at your diagram, wort collected in the centre of line 1 must
travel half of line 1, all of line 5 and half of line 4 to get to the
outlet.
With the drain in the centre of line 5, that same wort collected in
the centre of line 1 must travel only half of line 1 and half of line
5 to get to the outlet.
