So today I noticed a thumb size indentation in the pool floor. It’s About an inch deep. I went down to feel it and surprisingly it Dosent have any hardness underneath . It actually stretches if I push on it lightly. I didn’t want to push harder because I’m afraid it will rupture. Do you guys think it’s leaking already ? Or is it just a matter of time before it does leak ? It’s a vinyl liner and the pool was installed 2 months ago. What’s going on please help
