    completely clueless about pump choices

    I need to purchase a new pump and am not sure where to start. I have a 24x54in round above ground pool with sand filter. Is 1hp good? 1.5 hp? From what i have read its borderline? 1speed or 2speed. What is the best brand? I live in NC and the swim season is long and summers are HOT. (not sure if that has anything to do with it or not but just in case) Thank you, as always

    Assuming no spa, waterfall, or other water features: you want a 3/4 HP or smaller 1 HP two speed pump. 3/4 HP two speeds are rare, so usually you are forced to get a 1 HP. That will have the lowest lifetime cost and perform well with most pools, including yours.

    There are a number of good choices. I am fond of the Pentair Dynamo.

    Re: completely clueless about pump choices

    Many members have the Power-flo Matrix as well for above ground pools ... they run on 115V, probably like your existing pump.
    And definitely look at a 2-speed version.

    BTW, what pump do you have have and why do you need to replace it?

    Re: completely clueless about pump choices

    I have a 3/4 hp 1 speed that the lid cracked on The basket cover. its 115v and it barely powered my hayward diver dave vacuum. We had a "pool guy" come last year to open up our pool and he said our pump was too small? Best i can see is its a splapool? There is no other brand indication ....

    Re: completely clueless about pump choices

    OK, so the lid cracked and you think it is under powered.

    Well I think the 1HP Power-flo Matrix 2-speed would be a good choice then.

    Re: completely clueless about pump choices

    Yea u just figured to replace it altogether rather the put more $ in to a new lid on a pump that seemed insufficient. I appreciate your help!! BTW, how do u tell what size my sand filter is?

    Usually measuring the diameter of a sand filter is what is useful.

    Re: completely clueless about pump choices

    I noticed that the power Flo matrix is listed as 110v. My current pump is 115v. We have an electrical line professionally installed with 2 gfi outlets one of which we plug our pump into. Will the new pump be compatible?

    Re: completely clueless about pump choices

    Yes. 110, 115, 120v ... All the same thing.

    Re: completely clueless about pump choices

    Great, thanks! One further thing, I am comparing both pumps recommended by the two guys who have helped me on this post. They both seem to be great choices. The pentair dynamo stated that it does not come with a cord? Will my current cord be interchangeable?

    Re: completely clueless about pump choices

    I don't see why it would not be. Although I have no experience with these. I think often it is recommend to replace cords (for example, just got a new dish washer and was told that the warranty was void if I used the old power cord and did not get a new one. No idea how the power cord could wear out or how they could enforce that)
