Is 325 sf ft cartridge filter large enough?

[kpu1012]

Hi all,

I posted a couple of weeks ago asking for help selecting a cartridge filter. I have a 22,000 gal IG pool and the concensus was 425 sq foot filter. I informed the builder of my choice and he assured me that it would be at least 425 sq ft. Well, now that everything was installed, I went to update my profile with the actuals and he only installed a 325 sq ft filter :grrrr: .

I haven't made the final payment yet, so I am not concerned with the difference in price or that I didn't get what I paid for since I will make sure that we square up. My question is if I should live with the 325 sq ft filter or should I push him to exchange it for the larger 425 sq ft filter?

Thanks in advance.

What's in the contract?

There is a sand filter in the contract and I requested a cartridge filter at 425 sq ft as an upgrade. We have not yet settled on the up charge and that is why I am not concerned about the cost at this point.

I am confident that I can get him to swap out for a larger unit if it was really necessary - if I can get away with the 325 sq ft filter I would likely keep the one that is there now.

325 square feet is OK to use up to 122 gpm on a commercial pool, so that should give you good performance.

Just as JW said, the 325 will be fine. It should also come out to about the same cost as the sand filter.
