I'm new to this board and was hoping someone might be able to help me out. I have an American Titan Stainless Steel D.E. Filter for my inground pool. The Tension Control (I think that's what it's called), the piece that holds the top of the filter to the bottom and wraps around it, is broken and I need to get a new one. My problem is I can't tell whether I have a pre 1994 or post 1994 filter. All the websites that have the part I need have two versions of it. Does anyone have this type of filter? I was hoping someone might know where I can look it up by serial number or model number. I've done searches and can't find any information on how to tell. Can anyone recommend a website or provide any other advice?
