Hello all. After trying to muddle through spreadsheets and opinions to create my own... I'm lost. So I'll just throw it out there.
I moved into a TX house four years ago with the following set up:
12,700 gal Inground Pool
Pentair DE Filter
Speck 433T 1 1/2 HP Pump
The filter/pump set up sits about 2' below the water level and 20' away from the near edge of the pool
The pump bearing sounds like it's been getting worse over the past year (more and different sound/noise) and a seal is leaking, not a lot but probably 2-3 gallons/day running the pump 8 hours/day.
Since it looks like a pump replacement, I've been looking to move to something more efficient but affordable. Have narrowed my choice to Pentair Whisperflo or Superflow Dual Speed 1 or 1 1/2 HP, or maybe the EcoPump EP-4 or EP-6 (I have to admit the idea of having my water moving all the time is appealing).
Is 1 1/2 HP more than I need?
What's the difference between Up Rated Efficiency and Full Rated Efficiency on the Pentair pumps (WFDS-24 vs WFDS-4)?
I'm not looking to have the Cadillac of Pool Pumps, so VS is probably not where I'm going. Am I missing something? I see mixed reviews on EcoPump, but their EP-4 looks awfully inexpensive to operate with fewer fail points than some other uber efficient pumps.
Thanks in advance.
