Help with sizing new filter

[TomC]

My brother has an above ground oval pool, which is 15' x 30' x 48". He currently has a 1.5 HP Hayward pump and a broken DE filter. He is buying a new sand filter and needs to know the appropriate size. He is not averse to buying a new pump too, and emailed me this combo and wanted to know if it's ok for his pool.

Any and all advice appreciated.

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.
