I was personally more interested in a series configuration
because it appeared to simplify the plumbing, placement, and installation, and
because the makers seemed to imply that flow would be unimpeded by the second
pump. Thanks to Russell, we know that's not the case, so it's time to
reinvestigate the parallel configuration.
Just as a small
correction- it's Todd that's been testing the EWP's, though I do have two on
order that should arrive this week.
