I currently have a Pentair WhisperFlo WF-26 in place. It is a 1 1/2 HP and I have a ton of issues with my pool since we bought the house 1 year ago. I have a water heater that keeps turning off because there is not enough flow, I have algae that keeps coming back every 2-3 months even with me running this for a good 12+ hours a day and ensuring all my chemicals are in the proper amount. I have very little suction on my skimmer and thus when I vacuum there is little suction there as well. I also have a small bit of water that come out from the pump only when it is on. As well I also keep having a top layer of gunk on the water even after the motor has ran all day long (almost like its not being grabbed up by the skimmer). All of this has lead me to believe I need to replace the pump.
I need suggestions on a replacement that will resolve ALL of the above issues.
Will replacing it with the exact same make/model be the best? Should I be looking for another higher powered one such as a 2 hp? Which is better single speed or dual speed? How about things like the intelliflo? Is there any model that would be better and actually be more energy efficient for the amount of water it moves? I am not worried about cost of the overall unit I put in I just want something 1) reliable 2) not any more expensive to run than the current unit 3) quiet as possible 4) has a better flow rate that will fix the heater issue and the skimmer issues.
Anyone with thoughts or suggestions or is it really just as simple as speccing something with the same HP and then randomly picking a model?
