Does having that 3rd leg effect the flow? Would more get sucked in through the middle since it is a direct route out? (Especially since the "outer" 2 legs overpass the spigot, rather than connect close to it?
Mind you, I think regardless of which is used (2 legged loop, 3 legs with an overpass like yours or 3 legs that came together before the spigot) the differences would be negligible.
What size copper pipe for the manifold itself is recommended?
