Above ground pool wall problem

[hrsdennis]

A couple of more thoughts. The ability of the liner to stretch depends a lot on the age of the liner and the temp and amount of direct sunlight when refilling. Details here would be helpful.

The wall pulling in is surely due to shrinkage. The only damage occurs when the liner pulls loose from the top and water gets in behind it. If you can see the sidewall from inside the pool you have a problem.

The fix depends on what kind of liner you have, beaded, j-hook, overlap?

Thanks for the explanation, Dennis. There's no substitute for experience.

Would tension on the TOP of the wall, due to a shrinking liner ever cause the bottom of the wall to lift out of the track?

No Ben, that would be a different issue entirely. Most of the time that is due to a faulty installation, leveling issues. Occasionally severe freezing can cause this, like the ground under a couple of posts, sitting on blocks, could rise but the rail between posts would not.
