IG Floating Vinyl Liner

Thanks for the responses.

I understand to not let a pool overflow. However, there are a couple of inches above the liner attachment track before the pool overflows.

If you let the pool fill above the track but not overflow, is there a problem of water getting behind the liner through the track and causing the liner to float negating the advantage of having the extra water in the pool? In other words, do not let the water get above the track?

In my pool I would gain about 2 inches of area above the track while I have about 6.5 inches from the middle of the skimmer to track. In my latest situation the water was maybe a .25 inch below the track after the rain!

I don't think water that finds it way behind the liner via the track would cause problems, other then what the moisture might do, effecting the foam or the walls (if they are wood for example).

It's the pressure of the ground water rising up and under the wall then behind the liner that normally causes it to lift out of the track.

But to be on the safe side I'd keep it below the track. The extra few inches isn't going to make all the much difference. The pressure at the top most point of the pool's water isn't all that much.

If ground water has made it far enough to lift the liner up and out of the track, I don't' think the extra few inches above the track are going to stop it at that point.
