The previous owners replaced the vinyl liner in the fall of 2015. While cleaning along the edge today I noticed this:
I believe beyond the vinyl is steel frame. How do I fix this or should I just call the company that installed it?
From what I read here, water behind the liner is no bueno and that's what I'll have once people start splashing around.
