    What pressure should I expect

    Just turned on pump, there is gauge on the cartridge filter, it doesn't work, I have one on order, what pressure should I expect in a typical system?

    There really is not a typical pressure other than 0-30 PSI.

    Every combination of pool, pump, filter, and piping can all affect what pressure you will see as your "clean" and "dirty" pressures. About the only rule you can count on is that this site recommends that you clean your filter when the pressure is 25% greater than your "clean" pressure.

    ok, that's a rule of thumb to follow if the pressure drops 25% clean change.

    No if the pressure rises 25%
    Take for example 10 psi clean backwash at 12.5 psi
