Thank you for the response and I had read about the plunger but these are pretty bad and I don't feel like we should have to fix them considering it has not been a week since the liner has been installed. They did send someone out yesterday to look at the pool after I went to their office and showed them the pictures I had taken of how bad it looked, which is a plus. While thankful they said they would "try" to fix it he said something that worried me...He said that they would have to come back when it was hot (with no chance of rain) to stretch the liner and would put some water behind the liner to loosen the wrinkles. I thought that water behind the liner was a bad, very bad, thing and can not find anything online about that being a remedy for removing liner wrinkles. I am on the fence about letting them do that but then in the same sense they will not get paid anything else until the job is done correctly and to our satisfaction. Any idea about the water behind the liner??
