Does anyone else's vinyl liner bulge out in areas when raining? We have noticed this before, mostly in the shallow end, and it happened again today. We seem to notice it when we are wasting the pool when it's raining, so I don't know if it's just from the rain alone, or wasting + the rain. Never noticed it with wasting alone, so it definitely has to do with the rain.
Is this normal, and why does this happen? I assume it must have to do with the walls of the pool getting wet, but not sure.
The first time it happened, it seemed to go back to normal on it's own. Haven't checked this time yet if it popped back into place yet. Want to make sure there is no cause for concern.
