Ok, after reading all these good posts I knew I had to have a level and packed site. It took two weekends, but we got it done. I knew I wanted to use pavers under the posts and foam board insulation under the liner. So since the pavers and foam board need to be level, I thought it would be good to site the pavers, then cut the foam board to fit in the circle. I assembled the top rails by themselves to make the ring and positioned it on the site. I placed a heavy duty tarp, then put the pavers under each "t" so that the feet would be at the front of the pavers since it seemed most people said the bottoms of the legs kick out a bit and I also didn't want the liner to pinch onto the pavers. Next I cut the foam insulation circle to fit and double taped it with gorilla tape. I placed the tarp that came with the pool on top of the foamboard and opened up the pool. NOW THE TROUBLE STARTS: firstly, when the pool was fully assembled, I couldn't get the legs to line up on the pavers. Half were on and half were on the foam board in front of the pavers. It seemed the retaining rope was stopping the legs from being plumb. Is this on purpose??? So I untied it and placed the legs on the front edge of the pavers, fluffed and positioned the liner and started filling. After 2 inches of water I saw two issues: there were wrinkles that I could not get out of the bottom easily and the liner was skewed toward two opposite (!) sides, riding up on the pavers and it was pulled away from the other two "sides" by about 6 inches. I baled out most of the water, so I can move the liner better. WHAT DO I DO NOW? I thought I would at least try to center the liner better. What are your thoughts about the legs? pavers? rope? Sorry this is long, but I thought you might need my process.
