Not my pool…but my sisters pool.

2nd opening this year for this brand new pool. Last year upon opening, it had the same crinkled liner (shown in picture). PB said it was due to sump well not being drained. The liner was fixed by PB by draining half the pool and putting the vacuum and filling it back up.

Fast forward to this year and same old crinkle in the liner. Only difference is that the sump well was being drained throughout the winter.

Is this due to sump well? Or due to improper fit of the liner? Or something else?

I tried to move the thread under "opening/Closing" but unable to delete this thread.
