I recently bought a house in western Pennsylvania with a kidney-shaped pool that has a vinyl liner (27mm thick). What is the typical lifespan for these liners? Thanks!

Used to be 15-20 years, but it seems like 7–12 years is the new normal. Nevertheless, the other remarks are accurate in stating that most of the time, replacement is done primarily for aesthetic reasons. If you maintain your water appropriately balanced and are cognizant of the fragile nature of older vinyl, you can certainly still get 15+ years out of them. I have one client who has a liner that was initially a deep blue, it’s now virtually white, but still holds water and has no functional difficulties. That liner is twenty-five years old.

@Umbrielle There seem to be a few areas where the liner is fading more quickly than the surrounding region. There are probably two areas, each no bigger than a foot. Another is maybe five feet tall; they are all asymmetrical in form.
Chemicals and salt water are beneficial. Seasonal average for chlorine is 2.6.
What would cause fading in locations like that? I tried brushing, but it had no effect. Is it possible for the house’s windows to reflect something like that?

@AquaAdventurer Could it be that some kind of cleanser caused the wear? There was a Kreepy Krawly I had, and it would get caught in one spot and wear that region down.

I was told to be content with anything more than ten years.

Mine is seventeen years old. The design has faded a lot, notably on the floor of the pool. Beyond that, though, it appears to be functioning okay.

@Sadie That was when you could manufacture them with all the nice stuff, like oil, petroleum, etc., before regulations changed.
Because of current chemical rules, anybody who claims to have a liner that is more than 15 years old may really make anything in the same way today.
