    Default Pump and filter sizing

    Hi everyone,

    Just want to make sure that I have adequate sized equipment.

    10,000 gal fiberglass. 1.5 hp pump and 36 sq ft PE filter.

    Thanks

    Thank you. Just a waste of electricity or could it cause problems.

    BTW I have a heat pump also if that matters.

    the heat pump doesn't affect your pump, much- might slightly lower your water flow, which is probably a good thing in your case.
    The pump and filter matchup is the concern- if you overdrive the filter, it won't work as well and you could get to much pressure and damage the filter if it gets to extreme.

    Thank you. I'm considering buying a new filter. 48 sq ft DE. I have a Pentair 36 now, upgrade to a Pentair 48. I've always had cloudyness problems.

    Is this a sound decision?

    Alternatively, maybe buy a 1 hp pump instead of a new filter? Pumps are cheaper and perhaps more likely to fail being the reasons.

    Is 36 sq ft of DE (my current filter) adequate for a 10,000 gal in ground?

    i can't advise you on the DE filter but I will tell you that for a 10K pool, you don't need a 1 hp pump. I have approx. 13K and I have a 1/2 hp full-rated inground pump on my AG pool and a 200 lb. sand filter and that pump is plenty big for my pool.

    Other considerations for pump size would be if you also have a spa, water feature or anything else that might need higher flow rates. If not, then I agree with everyone else that you can go with the smallest pump possible.

    I'm hoping that a new pump will help eliminate my cloudy water problems. I've tried many things.

    Thanks everyone.
