I turned off water supply to house to replace shower cartridge. Water off for three or so hours. Turned water back on and "flushed" the lines. A few days later, turned on pool filler and got low pressure and almost no pressure everywhere else in house during fillup. HELP!

    Did the pressure go back to normal if you turn off pool filler?

Pool filler is leaking somewhere. I know the cartridge replacement seems suspect, but I believe that's just a coincidence.
