Help with sizing new filter

[TomC]

Is there a chart or table for filter/pump sizing that someone could point me to?

Thanks

I'll let Ben or Mark make a recommendation but the 18inch filter is way to small for a 1.5hp pump. Actually, that is way too much pump for a pool that size.

Thanks Watermom. He's going to get a pump/filter combo. What do you think of the combo in the link?

Thanks

OOPS. I didn't notice that it was a pump/filter combo when I looked at that link a few minutes ago. I looked too quickly and only saw the filter size.

See what Ben thinks. But, if it were me, I'd buy a bigger filter than the one in that combo. I've asked Ben to pop in to this thread and offer his opinion.

The 1.5 Hp pump is probably up-rated, meaning it is equivalent of 3/4hp full-rated pump, roughly, so not as seriously over-sized as a full-rated pump would be.

Thanks for the help guys

How to tell if pump is uprated or full rated?

Usually the flow rates tell you. Hayward above-ground pumps (and this is one) are generally up-rated, but we have folks here who are more knowledgeable about such details than me. Hayward's combos do tend to match the pump and the filter, but just barely. Ball-parking it, I'd sooner see you get that pump with the next size up filter--the 200# version (T210?) and you'd be sure the filter is adequate. I don't know why Hayward doesn't match them that way, and the 150# sand filter with the 3/4hp uprated pump. I have the 200# with the 1hp 2speed Superpump and it's adequate at full speed, but I've always wished I had gotten the 250# (the Superpump 1hp is more powerful than the pump you're considering).

Still, a Hayward combo set should have a warranty on the whole thing.
