My pool is now nine years old. I live in Toronto so this is a seasonal pool that is open (or at least uncovered) from mid-May to early-October. In the winter it is covered with a mesh safety cover. It is a salt water pool so I rarely add "chemical" chlorine, if that matters. Other than upon opening each year the pool hasn't had to be shocked as it has been kept clean and clear.
The pool has the original liner and the pattern on the vinyl liner is starting to fade a bit, presumably from UV or bleaching. And in a few spots where the Kreepy Krawly gets stuck there is a bit of pattern wear but it doesn't seem to have worn a hole.
Other than that the liner looks fine and there aren't any holes that I can see. Should I be thinking about replacing the liner in the off-season in the next year or two or should I just keep going until I see any rips or tears? And if I replace the liner is it better to do it in the fall upon closing or in the spring upon opening? I would think in the spring.
Is there anything else that needs replacing after ten years? I have replaced my Jandy Aquapure salt cells a couple of times, but haven't replaced the paper cartridge filter, but that should probably be done soon. The pump and heater are still original although parts of the heater have been replaced.
