We replaced our liner 5 years ago and now we have quite a wrinkle problem with it. We had the company that sold us the liner come in to look at it and they have told us that it's a chemical problem that has caused the wrinkles. We had had the previous liner for 16 years with just a slight hint of wrinkles at the end of its life as well as a few leaks which is why we replaced it and I suppose it was time. However, we didn't change anything chemically that we'd been doing for the previous 16 years. Is there any thing we can do to help the situation without having to replace the liner so soon? If you folks or any of your forum can offer any suggestions it will be most appreciated.
