    Unfortunately, that's a motor number, not a pump number.

    And GPM can vary with what size impeller, how long the pipes are, how high above the water the pump is, even how big the pipes are.

    Are you trying to figure out turnover time? Don't bother. Follow these instructions: Pool School - Determine Pump Run Time
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
