    Filter pressure

    When I switch from pool to spa I noticed the pressure gauge on the filter tank goes up a couple
    notches. Is this normal?

    Yes. You are forcing the return water through the spa jets which adds head loss and increased pressure in the filter.

    Pressure gage, filter cartridge, and bolt for the band that holds the thing together.
