    inground vs. above ground pumps

    Is there a huge difference between an above ground and inground pump of the same HP rating. For instance would this pump work in my 10K gallon in ground pool? I have a 3/4 HP pump currently.
    Size: 11370 gallons
    Filter: sta-rite cartridge
    pool: In-ground vinyl
    pump: ?

    The biggest difference is that some AG pumps are not self-priming like the one you chose. So it would not work well unless the pump is below water level.

    However, there are some AG pumps, like the Pentair Dynamo, that are self-priming but there are not many others.

    There is also a significant difference between the flow rates of an AG vs IG pump even for the same HP label.
