Hello everyone. We just became the owners of a passed down bestway 22x12 pool. Our friends used it last year. Cleaned the liner and stored it. They were kind enough to have their sons come and install it in our yard. But upon closer examination we see a lot of lighter spots where it looks like the liner is thinning? My husband is afraid these will open into holes flooding our yard and neighbors. The main area is where the liner was folded and you see a line of white Can I just patch these areas to be extra cautious? Or would it be best to buy a new liner or (what my husband wants ) a new pool. Really bad pics included.
