    Pump sizing help needed - 22k pool + 3 scuppers + 3 bubblers

    Thanks, everyone, for all the help so far. However, I need more!

    We are planning a pool (no spa) with the following specs:
    ~22k gallons
    1x24" scupper, 2x18" scuppers, about 1ft above water level
    3 bubblers
    3" suction, 2.5" returns
    ~30ft from pool to equipment, about level
    Polaris 280 with booster

    I would like to be able to run the pool, 3 scuppers, and 3 bubblers independently. I want to make sure the 3 scuppers have solid water flow so they don't just trickle. I want to bubblers to flow sufficiently as well, and often they will all be running at the same time.

    PB is suggesting a Pentair Intelliflow 3HP VS pump + Pentair 3HP booster pump + Polaris booster.

    Any issues with this setup? Any better recommendations?
    Build Complete! : 111ft pool + 8.5x5.5ft spa (12" raised), ~22k gallons, Shotcrete, Stonescapes MiniPebble (Aqua Blue), 3 scuppers, 3 bubblers, Large Tanning Ledge, Long Bench, Pentair: Intelliflow 3050 VS, 1.5HP WhisperFlow (scuppers), Quad 100 DE filter, MasterTemp 400k, IC60 SWG, Intellichem+Acid Tank, 2HP Silencer Blower, travertine decking (~680ft2), dry stack flagstone raised wall / spa spillway

    What flow rate do each of the water features require?

    Are you planning to run the water features all the time or are you ok with running them in exchange for the normal pool returns?

    I would really try to design the pool without any boosters as they will cost $$ to run. But it depends on the flow rate requirements.

    You can also ditch the Polaris booster by getting a cleaner that doesn't require a booster like ThePoolCleaner.

    According to 1 builder, the scuppers require about 75gpm total (5ft x 15gpm), and the bubblers require 75 total (3 x 25gpm). I believe the pool would require about 46gpm for 1 turnover in 8hours.

    I would probably want the ability to run the returns and the features at the same time, for those long summer days where the pool is being used and the features are on.

    So the total flow rate for the Scuppers and bubblers is 150 GPM which rules out a single pump
