    Cartridge presssure????

    My filters are running at about 4-6 over starting pressure. But the return isn't that strong at all. When should I rinse filter off. Been doing it about every 2 hours and it is getting exhausting. I just feel that it is not pushing enough water through when it is 4-6 or even 2 PSI over normal starting pressure. I need that return pressure to keep the pool moving.

    What is your starting pressure?
    Is that 4-6% or PSIG?
    You should clean the filter whenever the pressure rises about 25% above the clean pressure.
    It's very common when fighting algae to have to clean those filters a lot. Every hour is not unheard of.

    P.S. It would be better if you kept all your issues in one thread.

    It makes sense that your flow would be reduces at 16 to 18 psig if your starting pressure is 12psig.

    I can tell a difference when my filter pressure goes up 3 psig.

    Do you believe it is going up because my filter is getting clogged?

    The pressure is going up because your filter is collecting debris, just as it was designed to do. We recommend cleaning the filter any time the pressure goes up 25%, which would be 3 psi in this case.
