Al,

Thanks I prepped the pool liner last night. I figured I would try a few pieces tonight to know before trying it...

The liner must have shrank and pulled the screw holes (under the skimmer plate, causing the leak.

Thinking back I may have had some signs of this last year.

I checked behind the liner and there is no oxidation or rust going on at all. The screw mounts are harder to tell on material but It appears they are built into the metal wall behind the liner.

I will get before and after pics this weekend and have them up early next week.

Thanks to everyone so far.
