    I have a question before I buy a return pump. If you have a pump with 400 gph rating with a max lift height of 6’. Is the rating of 400 gph at the max lift height or at 0 lift.
    Thx in advance

    It's 400 at zero lift (immediately coming out of pump), and 0gph at 6'. The pump should have a chart that shows flow per height for values of height in between 0 and 6 feet.

    I need 450 gph I found a pump at 800 gph with a max lift of 9 feet so I should get more then enough with that one.
