Very slow leak...should I bother finding/fixing?

[waste]

Sorry for the delay! (my computer is acting up this week )

I don't think you have a leak

Your solid cover will accumulate water/ snow/ ice over the winter and displace pool water. Add to that the fact that water expands when it freezes and it's reasonable to expect a 4" loss in the spring. Also - if you have a hole in the solid cover, you'll be draining the pool when you pump the water off of the cover.

Enjoy your pool!
