[RE-wrenches] Booster pump

[Luke Christy]

Hi Nathan,
I am of the opinion that the booster pump should be on the output side  
of the main circulator, since when the booster pump is disabled it  
will represent a resistance to flow and you want that restriction and  
any resulting pressure losses to be on the output side of the main  
pump rather than the suction side.
Just my .02.

Thermal wrenches,

When plumbing a booster pump in series for a solar drainback system,  
should the booster pump go ahead of or behind the main circulator?

Cheers,
