I'm wondering, for all you SWCG cogniscenti: Should I install the manifold as close to the filter as possible, or as close to the return as I can? I also tee off to feed my solar panels, just before the return. Should the manifold come before or after the tee?

I'm guess that the closer to the filter is better as there is a minimum pump pressure required. But I'm also guess with my setup, where the distance from the filter to the return is less than 10' and a pretty straight shot, that it doesn't matter as long as the manifold is upright and well supported.

Any thoughts?
