My new pool was supplied with a loud 1.5HP Tristar pump/motor combo that I believe is way overkill since I don't have a spa or waterfall feature (I only have a couple of bubblers for what it's worth). Can I change out the motor and salvage the new wet-end pump? Initially I was intrigued by the idea of water turnover in a couple hours with the oversized pump so I didn't complain much when the PB chose it. However, I did not take the sound levels into consideration and are now bugging me. I figure that for my 9.5K gal I could probably get by with a 3/4HP motor. Would that still be the case for a 2 speed motor? Which would be the recommendation if any? Thanks in advance!
