So here is the newest problem this year.
We had a Noah's Ark kind of rain yesterday and the teenagers decided to swim in the rain. I went out to do my daily pool work and to my horror found a huge wrinkle that is about 8 feet long in the shallow end. I'm almost certain the liner floated for a bit and their feet moved it.
As some background, part of this wrinkle was already there when we bought the house last summer. I had two pool inspectors look at the pool before we purchased. The general consensus at that time was to leave that wrinkle alone. This was because the previous owners had lived there two years and said the wrinkle was already there and no one could tell us how old the liner was. The pool guys guessed it to have maybe 5-7 years before we would need a new liner. Plus the pool is a Buster Crabbe wood walled pool installed in 1980. As both pool guys said, a wood pool this age is a serious cave in risk whenever drained for liner work.
So now the wrinkle was gone from about 2 foot long to 8 feet long in a day. I'm not sure if I should just leave it alone or if I risk making a worse situation by messing with it. What is the downside to leaving a wrinkle? I have read about the plunger method to try and work it out. Is that advisable with a liner that maybe has 5-7 years of life left? Also, I doubt I will risk a cave in by draining the pool to fix this unless a long term wrinkle is a potential problem in itself.
