I'm pretty comfortable with chemistry and I know my way around a filter and pump, but I know nothing about pool construction or repair, so please be gentle.
I have a 33' AG Doughboy with a vinyl liner. I'm out mowing the lawn this morning and I see this piece laying on the ground next to the pool:
I take a look up under the top rail and see this:
The second picture above is with me gently pushing in on the pool wall so you can see the separation.
My questions are as follows...
1. What is the name of the white vinyl clip piece, and is there anything special I need to know about buying more?
2. Can anyone tell from the pictures what kind of setup I have, in terms of liner attachment?
3. Is there any special procedure I should use or special tricks I need to know for fixing/reattaching the new pieces?
Here are two quick shots of the top rail and the top of a post with the cover off:
The sections left and right of the one I took a picture of are both attached correctly. It's just this one section that I need to fix.
