It is too late now but I wish I hadn't done it. I tried to fix the leak by
removing the flange or face plate and regluging the liner. Oh, what fun.
I had more trouble lining up the holes in the face plate, the holes in the
liner and the screw holed in the skimmer. Took me more than a day. It's
done now and I hope it will work. Do I have a back ache!!

And it was definitely a leak between the liner and the skimmer. You could
see where silt had slipped down.

Gotta out and replace some rocks. Can't put add more water until the caulk
cures.

Thanks for the help.
