I'm visiting my grandmother here in Florida for a few weeks. I went out to clean her pool filter a week or so ago and noticed her filter cartridge was all ripped up. I ordered a new one and when I put it in, the automatic pool vacuum doesn't move and the jets stop. It is the exact same filter, and I noticed no differences at all. She has a Pentair Warrior DE Filter model number 56408800 with 88 gpm. What can I do to fix this? When I put the old cartridge back in, everything works fine, it just doesn't clean the pool well because of all the rips in the material. I would really like to get this repaired before I go back home in a week or so.
Oh, I also tried switching the panels from the new one to the old one. I thought that the top and bottom pieces might have been different, but that didn't help either. I'm open to any suggestions. Thanks.
