Been battling a Leak for nearly 2 years now and Cant seem to find it.
When I first suspected a Leak I made posts about it and tried to find it. I did find a leak where the pool latter on the deep end rests against the wall. It cut a huge gash in the Liner about 1 inch up and 1/4th an in across. I patched it, tested it with food coloring to insure it was not leaking anymore. All Seemed well. However the pool still seemed to leak at the same rate. Called in a pool company who verified to me that the patches I put on are holding, but could not find any leaks what so ever. The bucket tests shows 1.4 to .5 inch in the bucket and in the pool 1 to 1.5 inches a day.
Fast forward to pool opening day. Water drained all the way down 3 to 4 inches under that huge gash I mention before. Before refilling I took off the patch (it had a-lot of dirt behind it, but it was done underwater). I cleaned the area as best I could and re-patched. I also inspected the pool around the water line and at lest 5 inches above the water line to other holes. After I filled the pool back up and did the opening procedures.
Now it seems like I'm losing the same rate as before (bucket test exactly the same). I re-inspected that patch again with food coloring and it seems like nothing is leaking. I did not put the latter back since patching it the first time. There are two latter and I just left this one out.

I tried every trick I could think of and search on the internet about. I am on my last desperate move which is
1. Fix a Leak (I read all the posts on this site about it and countless reviews). I really don't want to do it becuase once its in the pool.. exactly how do I get it out? The instructions online say after 72 hours switch it back on to filter and filter it out. I have a DE filter and would it not just bind to my filter?
2. Complete pool renovation. The J-track is an old model and my cement is sinking in areas (been like that since I bought the house). New J-track, New Liner, New decking.
3. call in American leak detectors. However I refuse to pay 1500 dollars just for them to look (that what they quoted me). If I am going to pay 1500 for somebody to just look, I might as well go with number 2.
I want to do option 2 but not this year. But this leak is driving me insane. Anybody got any ideas before I go mad looking for the problem?
