I replaced my pool pump in 2019 with the INYOPOOLS Pentair WFE-4 1HP pump. I am also replacing the pool filter in 2020. Is this filter too big for my pool? 11,000 gallons. I live in Phoenix. Not sure what the flow rate is for the Pentair WFE-4 that I installed in 2019. PVC Piping is 2"

Hi Fred, Thank you for the detailed information that is super helpful. Yes this would be the perfect sized filter for the pool you described. The Waterway Crystal Water 325 Filter would be our suggestion for your pool and your Pentair WFE-4 pump.

I have an inground pool, with 1 HP pump motor. Is this filter too big for my pool? 25,000 gallons. I live in N. central Texas. Pool season is May until september depending on the weather. I have kept the pool open until November a few years.

Hi, Erika. This filter is NOT too big for your pool. It can be used if your pump's flow rate does not exceed 120 GPM.
