Does anyone know where I might be able to find a converstion kit for my Jacuzzi TriPlex 440 filter? I have seen reference to this kit online, and the only person who I have spoken to did not have this available anymore. I have the old style three sides filter elements, and these are not sold anymore. A conversion kit to use available filter elements, with the three necessary elements sell for over $600. I think it might be time to do something different.
