Hello all. I noticed over winter upon doing a quick check there was a sag right below the shallow end return jet. Didnt think too much of it at the time. But upon taking the cover off yesterday I noticed a star shaped set of small wrinkles in the shallow end bottom. Needless to say I was cussing up a storm. The winter here was a very wet one and spring has been the same. We have had about 8-10 inches of rain in the last month and a half alone. Any help or info on possible cause and fix is greatly appreciated.
