Wrinkles in above ground pool liner and bubble near top
I just bought a house with an above-ground pool in April. I have several neighborhood kids that have used the pool before I purchased it. Yesterday, one of them mentioned to me that he saw the liner was wrinkling where it had not been wrinkled last year. I remember seeing these wrinkles when the pool was opened by myself and the former owner and he (the former owner) did not point out the wrinkles as a problem. Are they or is it just cosmetic?
More worrisome is the 2 foot long bubble at the top of the liner near where the liner meets whatever it is that holds the liner onto the pool. I have not noticed a leak nor have I noticed that the liner is pulled away from the ring that holds it on. I AM VERY WORRIED. What do I do? Can it be fixed? Do I need to do anything right now? It feels like air beneath the liner not water. Any suggestions? Thank you.
