I have wrinkles in my liner that have progressively gotten worse over the last 3 years. When I noticed the first wrinke, I inspected it thoroughly to see if there was any puncture in the liner that could have caused it. I didn't find anything. It got worse later in the summer so I had our pool co come out to inspect it. They come out with scuba tank and spent a long time inspecting and also did not find anything. Suspected ground water. Now I have wrinkes all over the pool (shallow end and deep end). I recall when we first built the pool, our builder said that chemical imbalances can cause liner wrinkles. Our fill water is extremely hard. I typically have around 40ppm alkalinity, 500+ppm hardness and keep the PH at 7.5-7.6 all summer. I'm concerned about whether or not the low alkalinity and extremely high hardness could be causing the wrinkles? I don't think it is groundwater related because we've never had this issue in the prior 15 years of owning the pool. This liner is abut 8 years old and is the thickest gauge liner that they offered.
Liner wrinkles caused by chemical imbalance?

Got any pics ?
I've seen both in person and liner floating wrinkles will usually be flap like and long, maybe several of them in a general area streaking from one side to the other.
Low PH wrinkles (not low TA or high CH) will look like a fingerprint. The ridges/flaps will be less pronounced and there will be a million of them going every which way.
Here is a recent pic of a liner that floated from storm water.
This one looks like a low PH wrinkle. The ones I saw had many times more, across every inch.

I'll take some pics tomorrow and load them up. Thx
Looks like ground water issues not chemical problems.
As noted, low pH (below 5.0) will cause thousands of tiny wrinkles.
Large wrinkles are usually ground water.

Thank you. That is my suspicion as well. If we have the pool drained and inspect the liner and find it is still good, can the liner be stretched out and re-used, or is a new liner typically needed in cases like this?
Yes. It may not entirely stretch back the way it was. It also may get new wrinkles in a different way during the refilling process if it doesn't get lined up just so, or shifts a little as it fills. Or the folds could be creased and look better but still not perfect.
Messing with a liner is truly opening a can of worms and many just live with the cosmetic defect to not risk a spendy liner replacement. All liners are only so far from replacement anyway.
Try to check and address the ground water to prevent a reoccurrence.
