This probably makes me sound like an idiot, but here goes.
I have a Pentair Clean and Clear 200 filter. When I got the house, the former owner showed me how to change/clean the filter. I remember everything...except how to remove the pvc core from the middle of the filter. I have tried everything I can think of to get it to come out. I'm afraid I am going to ruin the filter, and I'm not ready to buy a new one yet. I have cleaned the filter a couple of times with the core still in place, but I don't get it as clean as when the core is out. I have tried searching to see if I could find something on the net, but I cannot. Anyone out there that can help me?
