I would like to use 10 waterway poly storm jets in the spa with 10GPM each, so 100GPM.
According to Hydraulics 101,
I would need perhaps a 3" suction and 3" return (or 2 2.5" return spa loops)
It seems I might be at 16' of head, plus pump and jets.
Hard to figure out jet head loss but I saw a thread that mentioned waterway and said 35' head loss.
Based on all this it seems like a dedicated 2HP pump might be fine?
Any reason to go with VF or VS for a spa jet pump?
Anyone have any experience with the triple jet assemblies from waterway jets?
