I'm In The Process Of Installin A 27' Above Ground Pool With A J-bead Liner. This Is All New To Me And A Long Learning Process (headache!). I Got The Wall Up Yesterday, Installed The Liner And Began Filling It With Water. All Looked To Be Going Well, I Had All The Wrinkles Out And The Liner Seemed To Be In The Correct Position, However, When I Returned To Check On It After Letting The Water Fill For A Couple Of Hours, One Side Of The Wall Was Bucklinf In Toward The Center Of The Pool. It Appears As The Weight Of The Water Is Pulling On The Liner And In Turn On That One Wall. No Excess Liner On The Other Side. Is This Common? Will The Pressure Of The Water When It Fills Push The Buckles Back Out Into Their Correct Position? Or Should I Drain The Pool And Start All Over. Help!
