New guy here.
I just ordered an Ecotech EZ VS motor/controller to replace my single speed Emerson 1081 EB843. This is a Pentair WhisperFlo pump WFE-8 (circa 1997). I will replace the seals in the pump when I upgrade the motor.
Anyone have experience with the motor? Search turned up only five hits, so seems this is an uncommon replacement.
For $400, I'm hoping to recoup my costs quickly in energy savings. I'm in CA where Tier 4 rates are ~$0.35/kWh.
