Consumer Comments:
"Hi Joe,
Pump arrived one day early. It took 20 minutes to get it wired and installed. It's a prefect replacement for the Aqua-flo Circ-master HP and at considerable savings. This pumps runs very quiet. If I didn't have the water fall on I don't think I'd hear it. Will be in the spa shortly.
Regards, Ken Ekern"
