Beaded liner problems

[bridrob]

Is it imperative that you use a shop vac to set your liner?
I have a Johnny weissmuller 24$ round in which we just replaced the liner. It was about 82° out, and the liner went in easily. I put about 6 inches of water in with no problem and turned off the hose because it was starting to get cool. By The next morning about 8 inches of the bead had popped out In 2 areas. It was replaced, but I realized that the liner was still about 3-4 inches from the wall as you went up the sides. I did not use a shop vac.

Any suggestions? I'm hoping.that it will stretch out o er the next few days. Should I continue to fill it, and as the water rises will the air get pushed out?.

thanks
