We've had lots of changes in the last year. Most notably we built a new house. A few months ago I took down a pool and moved it to the new house. It's a 27' round Mighty Sun Metal pool. I did not keep the liner. I'm wondering what kind of liner I need. The old liner I think was clipped in, like a j-hook liner. I was not smart enough to take a picture before I took it out. I'm looking through the original installation instructions that came with the pool and I see this. sorry for the long link. TFP wouldn't let me attach it and then it said the file was too large to link to. Anyway, the pic appears to show an overlap liner. Do I just need the overlap liner?
