My PB installed the plumbing yesterday and I noticed that the waterfall pump was a Supermax 2HP 2-speed pump. I was supposed to get a "Waterfall" pump from Pentair.
A quick calculation says I have about 15 feet or so of Head loss (waterfall 3' above pump, 60' of 2" pipe, 3" suction, and around a dozen elbows".) By reviewing the performance curve of the Waterfall Specialty pump it looks like it plays well with that amount of head loss but the Supermax pump is outside of its efficiency curve.
Will the Supermax be ok, or should I make the PB replace it with the Waterfall pump?
