I just wanted some advice. My liner has floated causing wrinkles once a season for the past three years. I have corrected different things each year (24/7 dry well pump, ground water drainage, drainage into a field tile) thinking that I have solved the problem and it keeps happening. I have narrowed it down to my water feature. This past weekend I had my water feature running for around 7 hours and my liner started to float again. I checked my dry well when it happened and it was empty. The pool looked like it maybe down an inch or two, nothing crazy though. I am not sure how it is happening. With having 16,000 gallon pool, should the weight of the water not hold down liner from the little bit of water that is getting behind it? I think there is either a leak in the water feature underground line or the water from the water feature is hitting the coping getting in between the liner and the coping. If anyone has had an issue like this in the past or think they know what is causing it could you let me cause I'm baffled. Thanks!
