The pool was given to me like this.Did you buy it like this?
thank you, i glued it this morning and will try to fill the pool tomorrow. I hope it worksI would attempt to patch it inside and out. Keep an eye on it and I would think it should be fine if set up level. Not sure how well it would work but I would also attempt to use a hole punch to punch the very end of the rip, it might keep it from ripping more. It's a trick used for cracks in metal/aluminum panel called stop drilling. I would think it would work on a liner like this also.
