Well I found where the water was going. I had a 2 foot tear straight across right at the water level. It is about inches up on the side. Must have happened when the heavy snow dropped the slab in the deep end. I lost about 5 inches of water cause of this tear. So what I did was take another piece of tarp, smeared it with e6000 and stuffed it on. I used Tyvek tape to hold it in place even better. Not sure this will work but I guess I will know in the morning.
1. How do you protect from having a 6ml tarp get damaged from the slab dropping.
2. Is there a better way to make the repair?
I am hoping I do not have to drain and start over as I already had to fix around 10 liner holes of various sizes.
