I am new to taking care of this 5yr old 18' round above ground pool that was installed partially on a hill in our backyard. They cut into the slope and leveled the area. The pool was neglected this summer by my spouse and I had no idea what I was getting into when I said I was going to get it back to the blue color before I closed it for the winter. If this pool is fixable, I will be the one taking care of it as my spouse lost interest in it. I proceeded to drain it last week when we had 60's-70's degree weather in GA. I had no idea that it could hurt the vinyl liner. I refilled it 2" and went to pool store where they sold me a bunch of stuff that I didn't need. I even bought a patch kit as I thought the water level had went down over the summer. I didn't think I had a leak. I even found what felt like a small rock under the liner on the bottom (opposite side of wall with hole in it now) and patched that. I don't think the rock had went through as the 2" water was still there when I got back from store with the kit and other stuff. The kit had a dye tester and it wasn't leaking so I proceeded to fill the pool back up. I filled the pool within the same day so it wasn't empty long.
I did get the pool blue again but I have found a small hole in the metal wall about 2 inches from the bottom of the pool now. I'm so frustrated that I don't know what to do. It has increased from a pin size to a BB size in the past week. There is a soft spot in the metal wall about golf ball size around this hole. The water has went down about 3 inches since last week. Our temps have went back down this week in GA so I haven't got in the pool to patch the hole in the liner. I believe that the hole is directly in same spot as the hole in metal wall as I can stop the water coming out the metal wall if I put the plastic net on opposite side of wall flush with the liner. It is 33 degrees here right now and I am not looking forward to getting into the pool to stop this leak. I bought Boxer patch kit and the Dye leak test kit. I do have a dive suit but I dislike cold temps. Can I drain this pool a little so that I'm not jumping in 4 foot of ice cold water? Please advice of how to fix my leaking pool. What is my first step? Stopping the leak in liner? How do I know if the leak was from the hole in the metal wall or just a tear in liner? I read a similar post and got some ideas as to what could have happened. I just want to fix this properly and not make anything worse.
Thank you for any suggestions,
