Need advice with pool pump and filter system

Hi,

I just bought my house last summer and it has an in-ground pool that is about 11000gal. The pump is a 1hp Centurion, and the filter is a Posi-Flo, the kind in a chrome tube about 4 feet high. The pump has lost its punch as of late, and it isn’t really pumping much water through the filter. The salesperson at Leslies laughed at my setup, so I feel its time to upgrade.However, I am very new to the whole pool pump/filter thing. I understand the differences between DE, sand, and cartridge filters. I’d like to stick with a cartridge filter as that seems to be basic to me. And I don’t really trust sales people because all they tell me is propaganda about new stuff that is out of my price range. So, can the experts here attempt to educate a rookie about pumps? Not necessarily specific brands, but basic differences between 2 speed motors, switchless motors, booster pumps, filter sizes and things like that. What would be a reasonable setup to upgrade to?

Please help.

I didn’t find the right solution from the Internet.

Thanks!

Thank you for contacting Inyo. For an 11,000 gallon pool, I’d recommend the Hayward C900 filter cartridge and the 1.65HP Pureline Prime model PL2605. The PL2605 is a variable speed pump and the most energy-efficient option.

Below are some resources that should answer any additional questions you may have.
