I noticed today that have very small cut in my pool liner the size of a small child's fingernail clipping. It is above the waterline on a liner that is less than 2 years old. Given the age, I assume its not from dry rot and the kids somehow cut it it with a toy.
Given the size is so small and that its about 2" from the top (lip) of the liner, I was considering patching it from the back of the liner. The reason is I still want a clean look above the water line. If this is not recommended, please advise and I'll follow the advice. It's almost in the center of the wall in the deep end (not a corner).
