So I am on my 3rd season with my pool. It is 17200 gallons run with a SWG. Everything has been going well until about 3 weeks ago where I noticed my liner above the water line was "sagging" - in addition the liner looked bumpy in some areas. It started to form directly across the skimmers (returns). First a little wrinkle formed, and then it spread. It should be noted I am heating the pool with the Hot Spot Energy Pool Heater (set at 90) The liner company is blaming it on the chemicals however I am religious with my testing (TF-100) and beyond me shocking the pool one time, the chemicals are right within range. The pool receives direct sunlight for 10 hours a day and I have an auto cover on it. Kids swim daily in it. The following is the history from this season:
I have additional pictures I can upload.
So is it that my pool is just getting to warm under the cover? Could it be a small hole I just have not yet found? When my water level is high it seems to exacerbate the problem. The liner company is standing by my chemical levels as the issue. Anyone have any thoughts?
