I have an 18ft prism intex pool. This is our 4th year with it and the second liner. It was purchased last year after the liner split open over the winter. I started filling the pool and noticed a pinhole leak. Moved some of the grass away to look at it. Put my finger on it and it became a 2 inch leak, just like that. I was thinking of patching it, but am concerned how easily it got larger. I am also concerned because this is the same area it split in the first liner. That ended up being about 3ft long. Could I make the patch a lot longer, just in case? Would I patch on the inside or is it possible to patch the outside? My concern is this is a defect in the liner. This is my 10th(?) year owning an intex and never needed to patch before. The first picture is of the 2022 leak on the old liner. Second picture is of the new leak on the new liner.
