    Psi 29 at speed 4. Do I need to be worried?

    Hi, I haven't done any cartridge filter cleaning since I moved into my current home with pool 15 months ago.

    Today I noticed psi is 29 at speed #4. I have variable speed pump.

    But, at speed #1 - psi is 2
    at speed #2 - psi is 14
    at speed #3 - psi is 18
    at speed #4 - psi is 29.

    Should I be worried. Verified that my gauge goes to zero when the pump is not running.

    Please advise.

    My current test numbers- FC - 7, PH - 7.4, TA - 90, CH - 625, CYA - 60

    That could be normal, although not likely a need to be running at that high a speed.

    I would clean the filter in any case. I just use a garden hose with a high pressure nozzle. My filter runs 10psi most of the summer and I clean it in the spring when I open the pool.

    Especially since we just had that dust storm roll through the other day I would definitely clean the filter. Howdy neighbor!

    Record the clean value at high, and clean when the pressure climbs 25% of the clean value.
