    Bought replacement pump, is it too big?

    I have an 18 foot above ground pool about 4.5' deep and my jacuzzi pump went last year after 20years of operation. So I went to the pool store and he sold me a hayward pump. Now I don't remember the specs of the pump but it creates a strong current around the pool. Is this normal behavior? I don't recall my old pump doing the same.

    Not nearly enough info to answer intelligently but I can give it a WAG.

    An 18 foot AG pool will do fine with a .5 to .75 HP pump. Anything larger is overkill.

    Sounds like...."Surfs Up!"

    You can try adding/replacing an eyeball in the return with a larger diameter hole and even aiming it down lower.

    Ok so I just found out the pump is a hayward Turbo Injection 1.5hp 2-speed. So replacing the eyeball would be the way to go? Do I have to lower the water level below the eyeball to be able to replace it?

    IMO, I'd take the pump back and go for a lower HP (0.5 to 0.75 HP as Dave said), 2 speed pump. It will save you money on operating costs and you won't have to worry about the flow creating white caps. Bad pool store advice on pump sizing.

    If your pool store only carries Hayward, this one might be a good option. Single speed, but lower HP.
