Above Ground Pool Lower Wall Buckling
I just had and 30 foot round installed and it has about a foot of water in it. The liner is extremely tight on one area and it is buckling the wall. You can't hardly even push the liner against the wall.
Should I drain and let the liner sit in the sun for a few days and then try again?
No, you do not want to drain it and let it sit. You may need to drain it and readjust it, but not let it sit. An empty liner will shrink when left empty, the opposite of what you want to happen.
What you probably need to do is shut the water off and and wait until the next day when the sun is high overhead and has had a good chance to warm the liner up. All vinyl needs is a little sun to soften up and stretch.
The difference is amazing. A liner in the shade becomes firm and non giving, as soon as a little sunlight is on it it softens right up and stretches.
I would just wait for the right time of day and finish filling it. At that time you should be able to get in the pool and push the wall out, the liner should give enough for you to do that.
