If you've followed me you know I've just had terrible pool problems for a few years. I think I've found the underlying issue. I've been using a Sta-Rite PLM100 cartridge filter, which I didn't realize until this morning has a max 30GPM flow rating, with a 70GPM pump for three years. So chances are that PLM100 is ruined, agreed? So which way to go? Buy a whole new matched pump and filter from a reputable dealer? That seems like the most expensive. Or find a filter that can handle a 70GPM flow and somehow cobble it onto the existing sta-rite base and do some repiping? That seems like the most work. Or replace the PLM100 cartridge and get a smaller matching motor/pump? Also it never dawned on me to hire a professional installer? Maybe that would be a good investment?
