I had a few notes & discussions about water getting behind the liner if you let the pool overflow past the track where the liner is attached to the pool.

Apparently some people are under the impression that you could let a pool overflow since the more water in the pool the less likely the liner will float. I was told not to let the pool overflow.

Any comments?

Perhaps there's not a definitive answer to this question since all the people I've talked to haven't had a situation where they had to let a liner pool overflow. With all the tropical depressions & hurricanes around lately, it's been possible to get 6-8" of rain overnight. Of course, with a power failure you might not have a choice since you can't dump water out of the pool.
