Sinking?

[Jamie]

My pool seems like its sinking. There are indents every so often throughout it. Like little holes. Whats happening? I have a vinyl lined pool.

I've been waiting to see a reply to this problem.
I have the same thing going on with my pool.
There aren't any leaks, just little dimples, and trails that are sunk in.
My professional installer thought possibly moles underneath.
Like you, I'm still waiting for a sensible explanation.

I too have sinking spots in my pools. I have problems with moles and crawdads in my yard. When we installed it 7 years ago they put hot lime under the sand before they put the liner in. Well that didnt help. I guess I just have to replace the liner.
