I'm finishing up a pool build and my water features have a 1.5HP pentair Whisperflo pump Model #011773. The pool/spa pump is a pentailr VS 3PH model# 011018. The water feature pump is way too loud and needs to be changed out. The 3HP Pool pump at full speed setting is probably half the dB of the "Whisperflo" pump.
I'm going to see if the PB will swap it out with a quieter pump, if not any ideas of quiet single speed pumps? I don't mind buying another VS pump if that is the only route to get the sound level needed but would rather save the money with a lower HP single speed since the pumps only requirement is running (3) 24" water sheers.
Is it possible to just purchase the motor/VFD assembly for the same VS pump I currently have and mount onto the 1.5HP pump housing(correct term?)
