Have an ABG Oval 12x18 with a 3/4HP pump and a Hayward S180T Sand Filter.
Anyway, last night, I just happened to notice that about seven bolts, from about mid-way up, where two of the pool walls meet, are peeking through the side one of the uprights. This upright is in a location where if I hadn't been lurking around it would have gone unnoticed. So, I can't say how long it has been like that. I had the liner replaced about two weeks ago so I don't know if it is a consequence of this, or some unnatural shift in the wall in that area (if that's at all possible).
When I feel the liner side of the bolts, I can feel the heads up and down the liner -- only in this location. I read the following post that said this isn't anything to worry about. But, of course, I don't want this new liner torn in that location given any stress from behind.
In my picture, from the side, the lower two bolts are actually resting up against the edge of the upright. So, I'm not sure if this is why I'm feeling the budge as it is preventing the wall from expanding out? I'm deathly afraid to pry the upright away or to pull the upright back -- if that can be done.
Requesting help as to what should be done -- if anything. Or, there really isn't anything to worry about.
