I agree that buying a new pump is better than paying for a new 2 sp motor. It costs more than a new pump to replace the motor because I would have to buy some other parts to install it. I checked out the Hayward SP15922S and it is 1 Hp. The Pentair Whisperflo pump I have is 3/4 HP and it is too big for my 8190 gal pool. Would a 1 HP be ok or should I look for a 3/4 HP 2 speed pump?
