If you have a bubble at the bottom of a pool or under a liner, depending on where it is, the weight of the water should take care of it. Sometimes when a liner is installed on an inground pool, customers notice that the new liner coves on the bottom of the pool vs. doing a 90 degree angle that they were used to seeing on their old liner. This is normal, it takes the liner a while to stretch into the corners (some liners may never stretch in completely depending on how they were made). Heating the pool also helps – the colder a liner is, the less stretchy it will be.

So give it some time to see how it ends up after a full season. Also note, that once a new liner is installed homeowners will start to notice all kinds of things that have always been there, but since the liner looks “new” their attention is drawn to other features that are probably old but feel new because of the new perspective!
