I've got an inground pool that's somewhere around 16,500 gallons and currently running with a Hayward Super II, 3/4 HP pump. I'm pretty sure the motor's dead and I was looking to replace it myself. I've been told I need to move up to at least a 1 HP motor... But then the stories start changing - one guy tells me I can drop it in, same impeller and everything will be fine.. another tells me I'd need a new impeller and I'd do better just replacing the entire pump.
Can anyone set me straight?
If I try to drop a 1 HP motor in place of a 3/4 HP motor, do I need to change/upgrade/swap anything else in the process?
